Dr.Warren is conducting a factorial ANOVA. She has the following Factor Notation: 2X3X3. How many IVs does she have? How many total groups are there?

3 IVS 18 groups total

300

To control for the effect of extraneous variables.

**Daily Double**

Name two types of reliability.

Inter-rater, inter-item, test-retest reliability

400
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.

400

What is the minimum number of participants needed in each group of a between subjects design to detect a strong treatment effect?

10-30 participants per group

400

Data are empirical when they are_____, _____, and  _____


observable or experienced, and verifiable through investigation.


400

Why do we write literature reviews?

1.) Develop an understanding current state of research on a topic 2.) Gain understanding of methods used 3.) Identify key findings

500
H1: Participants in the therapy treatment condition will have less depression than those in the control condition. 1.) What is the IV and DV. 2.) What scale of measurement is the DV on? 3.) What statistical analysis should be conducted?
1.) IV- Treatment condition/group DV- Depression score. 2.) Interval 3.) Independent T-test

Emily would like to conduct a Factorial Anova In SPSS, but is unsure how to do so. Brief explain to her. She needs to click.Analyze->__________, then _________->

Analyze-> General linear model-> Univariate.

500

You receive the following results from a t-test: Test value=4 

t=5.87

df=600 

sig=.021

Report this in apa style.(I.e t and p value) Is this test significant?

t(600)= 5.87, p< .05. Yes, it is significant

Name three (3) reason why Zimbardo's Stanford prison experiment was unethical


Violated Respect for persons, Beneficence, etc.

Harmed participants

Violated confidentiality

500
Define and describe the balancing technique for controlling physical extraneous variables.
Balancing controls extraneous physical variables by equally distributing their effects across treatment conditions. For example, running half of the subjects ?in each condition in the morning and half in ?the evening.
