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

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.

What is Diffusion and why is it a threat to validity?

The spread of treatment from the experimental group to the control group. It can mask the true effects of the experimental/treatment condition.

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


Violated Respect for persons, Beneficence, etc.

Harmed participants

Violated confidentiality

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.
