2. CS
3. LS
4. S
What are the 3 types of studies?
1. C
2. C
3. E
Lets Get Started..
Decide what you want to know about
Then….
FORUMLATE A HYPOTHESIS
A CLEARLY DEFINED STATEMENT OF
EXPECTED RESULTS.
EDUCATED GUESS…
TEST HYPOTHESIS
Determine the best method to use to test your hypothesis and then develop your procedures.
Determine if you need an experimental group and one or more control groups.
EXPERIMENTAL METHOD
You’ll need two different groups..
Experimental group-receives the independent variable
Control group- does not receive the independent variable
If………..(independent variable)
Then……….(dependent variable)
EXAMPLE
STRICT PARENTS RAISE CHILDREN WHO RARELY GET IN TROUBLE.
Agree / Disagree
The independent variable is the “if” part of the experiment
The dependent variable is the “then” part of the experiment-what you are
measuring.
MY HYPOTHESIS
Your hypothesis… parents and how they raise children…
WRITE ONE NOW…
IF..
THEN..
Placebo
Sometime a placebo is used in experiments
What's that??
Why?? Attempt to control other variables
Placebo
The POWER of SUGGESTION…
Hypochondriacs…
EXPERIMENTAL GROUP
EXPOSED TO THE
______________
WHAT YOU ARE TESTING
Control Group
______ EXPOSED TO THE
INDEPENDENT VARIABLE
SCENERIO
AT 3:00 A.M. IN NYC, KITTY GENOVESE WASATTACKED ON THESTREET IN FRONTOF HER APARTMENT. IT TOOK THE MAN OVER 30 MINUTES

MORE ACCURATE, OBJECTIVE DATA
PSYCHOLOGICAL TEST OFTEN COMBINED WITH THE INTERVIEW
PROVIDE SUBJECTIVE ANDOBJECTIVE PERSPECTIVE.
CASE STUDY METHOD
LONGITUDINAL METHOD
CROSS-SECTIONAL
LESS EXPENSIVE AND TIME-
CONSUMING THAN THE LONGITUDINAL METHOD.
NOT APPROPRIATE FOR STUDIES ONDEVELOPMENT OVER TIME.
CAN YOU TRUST THOSE POLLS
What do you think???
From what you now know about the standards of research studies, find out as much as you can about any study or poll that you read about in a newspaper or magazine.
