Research Methods in I/O Psychology

Steps in the research process

Types of research designs

Statistical concepts

Outline

• Requires a precise vocabulary.

• Has rules for collecting and organizing data.

• Based on a system of logic for decisions (called inferences) about the meaning of observations.

• Requires verification of these inferences.

Scientific Method

Step #1 of Research Process: Formulation of a problem

• Inductive Reasoning

• Deductive Reasoning

• Intuition/Common Sense Research

• Applied business problems

• Previous research

Step #2 of Research Process: Generation of hypotheses

• Variables– The elements that are measured in

research investigations

– Operational definitions

– Examples of variables in I/O research


• Hypotheses– Statements used in research methods

concerning the supposed relationships between or among variables

– Statements that guide what research methods are used

– Examples of hypotheses


• Theory or Model– The organization of certain beliefs into a

representation of the factors that affect behavior.

– A source of hypotheses or the result of tested hypotheses

– Example of a theory

Step #3 of Research Process: Choosing a Research Design

• Overview of Research Designs– Case study

– Correlational

– Experimental : Field and Laboratory

– Meta-analysis

• Practical Considerations of Research Designs for I/O Psychology

Step #4 of Research Process: Collection of Data

• Sampling– Methods for selecting participants in a

study.

– Population vs sample

– Sample Size: Statistical and practical significance


• Sampling– Types of sampling

• Random

• Systematic

• Stratified

• Convenience


• Measurement of Variables– Types of Measures

• Self-report

• Observation

• Objective outcomes


• Measurement of Variables– Types of response formats

• Likert-type

• Semantic Differential

• Fixed alternative

• Open-ended

Step #6 of Research Process: Analyses of Data

• Qualitative vs. quantitative analyses

• Descriptive vs. inferential statistics

• Using computers to analyze data

• Understanding analyses conducted in published research

Step #7 of Research Process: Interpretation of Research Results

• Determining whether the hypothesis was supported

• Assessing alternative interpretations for the data

• Serendipity

• Research is a cumulative process

Research Designs: Case Studies

A one-time-only assessment of behavior or the application of an intervention to only a single group, department, or organization.

Research Designs: Case Studies

• Limitations- Cannot draw any firm conclusions- Usually lacks systematic measurement- Cannot address cause and effect

• Advantages- Generate future hypotheses- High in realism- Can examine topics difficult to study with other designs.

Research Designs: Correlational Studies

Examines the relationship among or between variables as they naturally occur.

Questions Addressed:- Does a relationship exist?- How strong is the relationship?- What direction is the relationship?

Research Designs: Correlational Studies

• Advantages:- Relatively easy to conduct research- Can examine topics difficult to research with other methods

• Disadvantages:- Cannot address cause and effect

Research Designs: Experimental Studies

A research design characterized by a high degree of control over the research setting to allow for the determination of cause-and-effect relationship among variables.


Three conditions must be present:- a variable must be manipulated- random assignment of participants to experimental groups.- control of extraneous and confounding variables.


The terminology of experiments:- Independent Variable (IV)

- Dependent Variables (DV)

- Internal Validity

- External Validity


• Laboratory settings– Offer the greatest level of control

– Cause-and-effect interpretations

• Field settings– Natural settings

– Quasi-experiments


• Advantages– Helps to explain human behavior at

work through cause-and-effect inferences.

– Controls for alternative explanations for research findings.


• Disadvantages– Cost

– Demand Characteristics

– Hawthorne Effect

– External Validity Issues

• Participants

• ecological validity

Research Designs: Meta-Analysis

A technique that allows for several different research studies to be combined and summarized.

Research Designs: Meta-Analysis

• Advantages– Provides a better estimate of the “true” relationship between

variables than the results of a single study.

• Disadvantages– Garbage in garbage out– File drawer effect

Descriptive Analyses• Frequency Distribution• Measures of Central Tendency

– Mode– Median– Mean

• Measures of Variance– Range– Standard Deviation

Distributions of Data

Inferential Analyses

• Inferential statistics are used for analyzing data to test hypotheses.

• Statistical significance refers to the probability of a particular result occurring by chance, used to determine the meaning of research outcomes.

• p < .05 means that the probability that the finding are due to chance alone is less than 5 in 100.


Reject NullHypothesis

Retain NullHypothesis

Null Hypothesisis True

Type IError

CorrectDecision

Null Hypothesisis False

CorrectDecision

Type IIError


• Analyses for Experimental Designs– t-tests– Analysis of Variance (ANOVA)

• One-way ANOVA• Factorial ANOVA• Main Effect• Interaction

– Multivariate Analysis of Variance (MANOVA)

Inferential Analyses• Analyses for Correlational Designs

– Pearson Product-Moment Correlation Coefficient• represented by r• can range from -1 to +1• the sign of the r indicates whether the variables are

positively or negatively related• the absolute value of r indicates the strength of the

relationship. The closer to |1 |, the stronger the relationship. An absolute value of 1 indicates a perfect relationship and a value of 0 indicates no relationship

• Correlation does not imply causality

Other Statistical Analyses• Multiple Regression - assesses the relationship

between multiple predictors and a single criterion.• Factor Analysis - methods of reducing a large number

of variables to a smaller number of variables, or “factors”.

• Structural Equation Modeling - a statistical technique that “simultaneously” examines the relationships among many variables.

Ethical Considerations for Research in I/O Psychology

• Confidentiality

• Informed Consent

• “Overselling” Research Results

• APA’s Ethical Principles in the Conduct of Research
