									             Chapter Two: Research Methods – Notes Summary
Lesson One

Why is replication of research important in psychology?



Create a “word problem” and select both the Independent variable and dependent variable in your
example.

 Example:




      IV:

      DV:


What is a good way to remember the difference between IV and DV?



                 Population:                                   Sample Population:




Why is random selection important in research?




Why is it important to have both an experimental and a control group?




How can confounding variables decrease the effectiveness of your research?
Lesson Two:

                                  Types of Experimentation:

   Types of                Description / Examples              Positives           Negatives
Experimentation



Naturalistic
Observation




Surveys/Tests




Controlled
Experiment




Case Study




What is the difference between:

      Reliability –


      Validity -

Why are none of the above types of experimentation the same as a controlled experiment?
Lesson Three:

                          Ways to Eliminate Confounding Variables:

       Way to Eliminate                                     BIG IDEA
     Confounding Variables:

Single-Blind Procedure


Double-Blind Procedure


Placebo


Counterbalancing


Do you think the placebo effect happens to people on a regular basis? List and describe several
examples:

1.


2.


3.


Lesson Four:

                     Studies that lead to APA Ethical Guideline Practices:

       Research Study                   Why it Would be Considered Unethical Today

Harlow’s Attachment Study



Stanford Prison
Experiment


Milgram’s Obedience
Research
APA’s Rules for Animal Research:

1.



2.



3.


APA’s Rules for Human Research:

1.



2.



3.



4.


Why do you think it is important for the APA to have rules regarding animal and human research?




What is your view on animal research?




What is the job of the Institutional Review Board?
Lesson Five:

What is the difference between:

        Quantitative Research –


        Qualitative Research –

                                           Types of Scales:

 Type of Scale:                                        Description:



Nominal



Ordinal



Interval



Ratio:


                                  Ways to View Descriptive Statistics:

   Way to View                                      What it Looks Like:
   Descriptive
    Statistics:


Frequency
Distribution


Histogram



Frequency
Polygon
                         Measures of Central Tendency and Variability:

Measure of                                             Description:
Central
Tendency:


Mode


Median


Mean


Range


Standard Deviation Chart:




If the above chart was a representation of a test that was taken in class, what assumptions could
you make?




Why is the phrase “correlation does not imply causation” important to follow when doing statistical
research?




Which of the following shows a stronger rate of correlation: (-.34, -.44, .44, .97, -.97) – Why?
