Name the four (4) scales of measurement

Nominal, Ordinal, Interval, Ratio

200

A ___________ is an interaction among three or more IVs.

higher-order interaction

200

A between-subjects design where there is one IV with three levels and subjects are randomly assigned to one of the three conditions. Be specific.

Multiple Independent Groups Design

200

Participants agree to participate in a study after receiving information about the nature, risks, benefits, and purpose of the study. This is called:

Informed Consent

300

In this type of sampling, the researcher uses participants to find other participants. 1.)What is it?

2.) What is a potential threat to validity with this sampling method?

Snowball sampling. Selection threat, because participants are likely to find people similar to themselves( i.e. friends and family)

Dr.Warren is conducting a factorial ANOVA. She has the following Factor Notation: 4X2X3. How many IVs does she have? How many total groups are there?

3 IVs, 24 groups total

300

Why is matching used?

To control for the effect of extraneous variables.

Name and describe three (3) types of reliability.
1.)Interrater reliability is the degree to which observers agree in their measurement ?of the behavior. 2.) Test-retest reliability means the degree to which a person's scores are consistent across two or more administrations of a measurement procedure. 3.) Inter-item reliability measures the degree to which different parts of an instrument (questionnaire or test) that are designed to measure the same variable achieve consistent results.

What is a post hoc test and why is it used?

ANOVA test tells you whether you have an overall difference between your groups, but it does not tell you which specific groups differed - post Hoc tests do. Post Hoc tests indicate which group means are statistically significantly different from one another.

1.) IV- Treatment condition/group DV- PTSD test scores. 2.) Interval/Ratio 3.) Independent T-test

 Dr. Brantley would like to assess the effect of meditation (weekly vs daily) and exercise (1x week, 3x week, 5x week) on depression scores among a sample of 300 young adults.

She random assignments participants to the above conditions. 

1.) What type of design is she using? 2.) What type of data analysis would she use to answer the research question?
 


1.) Factorial Design 2.) Factorial Anova
