ATTITUDE
Your attitude, not your aptitude, will determine your altitude.
ZIG ZAGLAR
WHAT IS AN ATTITUDE?
An attitude is a mental state involving
beliefs, feelings, values and dispositions
to act in a certain way. It can further be
understood as a learned predisposition
to respond consistently in a positive or
negative manner towards different
aspects of the world”
REASONS FOR MEASURING ATTITUDES
Attitudes lead to behavior More feasible to ask questions on
attitudes than to observe and interpret behavior
Large capacity for diagnosis and explanation
ATTITUDE RESEARCH
Attitudes directly affect decisions and these in turn, directly affect behavior.
AttitudeAction/
Behavior
MAJOR COMPONENTS OF AN ATTITUDE
COGNITIVE
AFFECTIVE
BEHAVIORAL
COMPONENTS OF ATTITUDE
COGNITIVE ATTITUDE INCLUDES:
Memories.
Evaluations.
Beliefs about the properties of the
object.
COMPONENTS OF ATTITUDE
AFFECTIVE ATTITUDE INCLUDES:
• Feelings.
• Intuitions.
• Values and Emotions towards the
object .
COMPONENTS OF ATTITUDE
BEHAVIORAL ATTITUDE INCLUDES:
• Behavioral Intentions towards an
object.
COMPONENTS OF ATTITUDE
EXAMPLE: If a person says that he likes LAYS CHIPS
because they are tasty & crispy and always eats them, the statement comprises all these three components of an attitude.
RELATIONSHIP BETWEEN ATTITUDE & BEHAVIOR
The attitude-behavior relation is not straightforward but they can be linked. Behavior can influence attitude.
EXAMPLE A product or service usage will be maximum
if the person develops a positive attitude towards it. The converse is also true Attitudes of consumers towards products that they have never tried will be neutral When attitudes are developed based on actual trial and experience of a product, attitudes predict behavior effectively
RELATIONSHIP BETWEEN ATTITUDE & BEHAVIOR
• Business researchers treat attitudes as hypothetical constructs due to their complexity & the fact that they are inferred from the measurement data not actually observe.
• Attitude provides researchers insights about behavior.
CHANGING ATTITUDES
• Marketers attempt to change existing attitudes to attract people and increase market value. For this, they resort to three major tactics:
Altering existing beliefs about a product. Changing attitudes by changing the
importance of beliefs. adding new beliefs
MEASUREMENT & SCALING OF AN ATTITUDE
Measurement Standardized process of assigning
numbers or other symbols to certain characteristics of objects of interests according to pre-specified rules
Characteristics for Standardization One-to-one correspondence between the
symbol and the characteristic in the object that is being measured
Rules for assignment should be invariant over time and the objects being measured
MEASUREMENT & SCALING OF AN ATTITUDE
Scaling Process of creating a range
on which objects are located according to the amount of the measured characteristic that the object possesses.
Type of Measurement Scale
Types of Attitude Scale
Rules for Assigning Number
Typical Application
Statistics / Statistical Tests
Nominal Dichotomous “yes” or “no” scales.
Objects are either identical or different
Classification (by sex, geographic are, social class)
Percentages, mode / chi -square
Ordinal or Rank Order
Comparative, Rank order, Itemized Category, Paired Comparison
Objects are greater or smaller
Rankings (preference, class standing)
Percentile, median, rank-order correlation / Friedman ANOVA
Interval Likert, Thurstone, Stapel, Associative Semantic-Differential
Intervals between adjacent ranks are equal
Index numbers, temperature scales, attitude measures
Mean, standard deviation, product moment correlations / t-tests, ANOVA, regression, factor analysis
Ratio Certain scales with special instructions
There is a meaningful zero, so comparison of absolute magnitudes is possible
Sales, incomes, units produced, costs, age
Geometric and harmonic mean, coefficient of variation
Types of Scales & Their Properties
MEASUREMENT SCALES: NOMINAL
Numbers identify and classify objects No ordering or spacing are implied Only possible arithmetic operation is a
count of each category Examples:
Players in a football team Colors of traffic light Gender
MEASUREMENT SCALES: ORDINAL
Objects are ranked in order Numbers indicate the relative
position of objects but not the magnitude of difference
Arithmetic operations are limited to statistics such as median or mode
Examples: Result of 100 meter dash Ranking of largest fast food companies
MEASUREMENT SCALES: INTERVAL
Object is measured on a continuum Arbitrary zero point Differences between objects can be
compared Entire range of statistical operations
can be employed (mean, correlation, ANOVA, regression)
Examples: Temperature Attitudes
MEASUREMENT SCALES: RATIO
Interval scale with fixed zero point
Ratio of scale values can be computed
Examples: Weight, length Age Store sales Market shares
ATTITUDE RATING SCALES
Present a respondent with a continuum of numbered categories that represent the range of possible attitude adjustments
Single item or multiple item scales
ATTITUDE SCALES
Attitude scales exist for each measurement type
The rating scale (interval data) is the most common type of attitude scale
CONTINUOUS SCALES
Respondents rate objects by placing a mark at appropriate position on a line running from one extreme of the criterion variable to the other.
Easy to construct
How would you rate Sears as a department store?Version 1:Probably the worst --------------------------------------------
Probably the best
Version 2:Probably the worst --------------------------------------------
Probably the best 0 2 4 6 8 10
SINGLE ITEM SCALES Only have one item to measure a construct Itemized-category scale is most widely
used by marketing researchers Other single item scales
Comparative Rank-order Pictorial Constant sum
ITEMIZED CATEGORY SCALES
Scales in which the respondent selects from a limited number of categories
What is your overall satisfaction with McDonalds Hamburgers?
Very satisfied Quite Satisfied Somewhat satisfied Not at all satisfied
RANK ORDER SCALES
Scale in which the respondent compares one item with another or a group of items against each other and ranks them
Brand AFlavor BSize A
Brand AFlavor BSize A
Brand BFlavor CSize C
Brand BFlavor CSize C
Brand BFlavor ASize A
Brand BFlavor ASize A
CONSTANT SUM SCALES
Respondents allocate a fixed number of rating points among several objects to reflect relative preference
Divide 100 points among the following attributes of a PC
Clock Speed: 30Hard drive size: 20RAM size: 10Price: 40
PICTORIAL SCALES
Various categories of the scale are depicted pictorially Format must be comprehensible to respond and allow
accurate response
Example: The taste of Honey Munch Cereal is:
DESIGNING SINGLE ITEM SCALES
Number of Scale Categories 2 to 15
Strength of the Anchors colorful vs. very colorful vs. extremely colorful
Labeling of the Categories no labels vs. some labels vs. all labels
Balance of a Scale balanced vs. unbalanced
MUTIPLE ITEM SCALES
Developed to measure a sample of beliefs toward the attitude objects and combine the set of answers into an average score
Multiple item Scales Likert Semantic Differential Stapel Associative Scaling
LIKERT SCALES
Requires respondent to indicate degree of agreement or disagreement with a variety of statements related to the attitude object
Typically used for intangible constructs. Each item (statement) measures some aspect of the common construct.
Scores on individual items are summed to give total score for respondents
LIKERT SCALES
Satisfaction survey for a bank:Strongly
Strongly Disagree Disagree Neutral Agree Agree
1. The bank offers courteous service
2. The bank has convenient locations
3. The bank has convenient hours 4. The bank offers low interest
rate loans
Together, the 4 items constitute the scale
This is a single item
ANALYSIS OF BANK SURVEY
Assign numbers to categories 1 2 3 4 5
Strongly Strongly Disagree Disagree Neutral Agree Agree
2. Compute results:a) for each item compute mean across respondents (e.g. the average score for all respondents for item 1 is 3.5)b) for all items compute mean for each respondent (e.g. the average satisfaction score for respondents 1 is 3.0)
SEMANTIC DIFFERENTIAL SCALE
Respondents rate each attribute object on a number of five or seven-point rating scales bounded by polar adjectives or phrases
With bipolar scale, the midpoint is a neutral point Used for image analysis, profile analysis
SEMANTIC DIFFERENTIAL SCALE
The semantic differential is a seven-point rating scale with end points associated with bipolar labels that have semantic
meaning.
SEARS IS:Powerful --:--:--:--:-X-:--:--: WeakUnreliable --:--:--:--:--:-X-:--: ReliableModern --:--:--:--:--:--:-X-: Old-fashioned
The negative adjective or phrase sometimes appears at the left side of the scale and sometimes at the right.
This controls the tendency of some respondents, particularly those with very positive or very negative attitudes, to mark the right- or left-hand sides without reading the labels.
Individual items on a semantic differential scale may be scored on either a -3 to +3 or a 1 to 7 scale.
Characteristics of Semantic Differential
Pairs of objects or phrases must be meaningful in market being studied and often correspond to product/service attributes
Avoid "halo" effect by placing negative pole on either side
Category increments are treated as interval scales so group mean values can be computed for each object on each scale
May also be analyzed as a summated rating scale
Characteristics of Semantic Differential (Contd.)
Profile Analysis Application of semantic differential scale Plot mean ratings of each object on each scale for visual
comparison Overall comparison of brands hard to grasp with many
brands and attributes Not all attributes are independent
Multiple-item Scales (Contd.) The Stapel scale is a unipolar rating scale with ten
categories numbered from -5 to +5, without a neutral point (zero).
This scale is usually presented vertically.
SEARS
+5 +5+4 +4+3 +3+2 +2X+1 +1
HIGH QUALITY POOR SERVICE-1 -1-2 -2-3 -3-4X -4-5 -5
The data obtained by using a Stapel scale can be analyzed in thesame way as semantic differential data.
Balanced & Unbalanced Scales

GRAPHIC RATING SCALE
Respondents select a point on a graphic continuum anchored at the extremes
CUMULATIVE SCALES
The cumulative scale or Guttman scale measures to what degree a person has a positive or negative attitude to something. It makes use of a series of statements that are growing or descending in how positive or negative a person is towards the subject. If for instance on a scale with seven statements the respondent agrees with the fifth statement, it implies that he or she also agrees with the first four statements, but not with statement number six and seven.
CUMULATIVE SCALES
PAIRED-COMPARISON SCALES
- Paired comparison scales ask a respondent to pick one of two objects from a set based upon a given criterion
Example - Which brand do you prefer? ___ Coca-Cola ___ Pepsi ___ Pakola ___ Pepsi___ Coca-Cola ___ Seven-Up___ Pakola ___ Seven-Up
Q-SORT METHODOLOGY
In the Q-sort method, the judge or evaluator is given a set of statements or items previously developed or fixed upon. This set of statements constitutes the entire vocabulary the judge is permitted to employ. A language, however, is more than a vocabulary; it requires a grammar as well. In order to complete the requirements for comparability of descriptions, we must ensure that this vocabulary is used, at least formally, in identical ways.
Q-SORT METHODOLOGY
Example: Personality & Psychology Assessment
Tests
FORCED CHOICE RATING SCALES
A forced-choice rating scale will bias results by eliminating the undecideds and/or those with no opinion. Some researchers will purposely leave out the response choice of "undecided," "no opinion," "uncertain," or "don't know." This approach may be reasonable when the researcher has good reason to believe that virtually all subjects have an opinion and you do not want them to "cop out" by indicating they are uncertain. What happens if many subjects are indeed undecided and we do not allow them the option of no opinion? Most will probably select a rating from the middle of the scale, e.g., "average" or "fair." This will cause two biases: (a) it will appear that more subjects have opinions than actually do (b) the mean and median will be shifted toward the middle of the scale. (The "undecided" category is not part of the scale.)
Steps in multiple-item scale development
Determine clearly what you are going to measure
Generate as many items as possible
Ask experts in the field to evaluate the initial pool of items
Determine the type of attitudinal scale to be used
Include some items that will help in the validation of the scale
Administer the items to an initial sample
Evaluate and refine the items
Finally, optimize the scale length
Potential Sources of Error on Measurement
1) Other relatively stable characteristics of the individual that influence the test score, such as intelligence, social desirability, and education.
2) Short-term or transient personal factors, such as health, emotions,and fatigue.
3) Situational factors, such as the presence of other people, noise, and distractions.
4) Sampling of items included in the scale: addition, deletion, or changes in the scale items.
5) Lack of clarity of the scale, including the instructions or the items themselves.
6) Mechanical factors, such as poor printing, overcrowding items in the questionnaire, and poor design.
7) Administration of the scale, such as differences among interviewers.
8) Analysis factors, such as differences in scoring and statistical analysis.
COMMON ERRORS THAT OCCUR WHILE MEASURING ATTITUDE
Central tendency error refers to a type of rating error in which a rater consistently rates all employees in the middle of the scale, regardless of their actual levels of performance.
EXAMPLE: In performance appraisals or recruitment interviews, tendency of managers and interviewers to rate all or most of the employees or interviewees as average.
COMMON ERRORS THAT OCCUR WHILE MEASURING ATTITUDE
Linenacy error : A systematic error where pieces of data are consistently overly positive. This is usually due to the researchers tendency to be too positive or tolerant or shortcomings in the research.
EXAMPLE: A manager or interviewer rates an employee or the candidate too positively, causing a performance appraisal or interview bias.
COMMON ERRORS THAT OCCUR WHILE MEASURING ATTITUDE
Halo effect The halo effect is a term used to describe how a
manager can be influenced by a single or outstanding employee characteristic, clouding his judgment on the employee's other traits. The halo effect can impair judgment to such a degree that hiring decisions are negatively affected and the company suffers. The employee pool can end up being one-dimensional rather than comprised of people with multiple layers of talent and ability.
Accuracy of Attitude Measurements
Validity An attitude measure has validity if it
measures what it is supposed to measure
Face Validity The extent to which the content of a
measurement scale appears to tap all relevant facets of the construct
Construct Validity A scale evaluation criterion that relates to
the underlying question "what is the nature of the underlying variable or construct measured by the scale?"
Accuracy of Attitude Measurements (Contd.)
Convergent Validity A form of construct validity that represents the
association between the measured construct and measures of other constructs with which the construct is related on theoretical grounds
Discriminant Validity A form of construct validity that represents the
extent to which the measured construct is not associated with which the construct is related on theoretical grounds
Accuracy of Attitude Measurements (Contd.)
Reliability The consistency with which the measure produces
the same results with the same or comparable population
Sensitivity Extent to which ratings provided by a scale are able
to discriminate between the respondents who differ with respect to the construct being measured
Relevancy Relevance = reliability * validity
Reliable? Valid?
Generalizable?
Scales in Cross-national Research
Responses Can Be Affected by Low literacy and educational levels Culture in a country Semantic differential scale is closest to
pan cultural scale Adapting response formats, particularly
their calibration, for specific countries and cultures
THATS AN ATTITUDE!
My attitude is that if you push me towards something that you think is a weakness, then I will turn that perceived weakness into a strength.
