Factorial Design
Researchers repeat published studies to confirm the results in the process known as_________
Replication
A _____ research design examines changes over time in one group of participants.
Longitudinal
An interaction occurs when____
The combined effect of two factors (and at least one condition from each) having an effect on the dependent variable.
The effect of one factor depends on the level of the second factor.
________is a statistical estimate of the size or magnitude of a treatment effect.
Effect Size
Sampling effects our ability to generalize our results from the sample to the population. This is also known as______ validity
External
_____ analysis is a technique used to analyze the content of media sources like films and news articles.

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
A design where there is one IV with two levels and subjects are randomly assigned to one of the two conditions. Be specific.
Two Independent Groups Design
Name 3 characteristics of a good hypothesis

Name and Describe three threats to validity
History threat occurs when an event outside
the experiment threatens internal validity by changing the dependent variable.
Maturation threat is produced when physical
or psychological changes in the subject threaten internal validity by changing the DV.
Selection threat occurs when individual differences are not balanced across treatment conditions by the assignment procedure.
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.
Emily would like to conduct a Factorial Anova In SPSS but is unsure how to do so. Briefly explain to her. She needs to click.Analyze->__________, then _________->
Analyze-> General linear model-> Univariate.
Data are empirical when they are_____, _____, and _____
observable or experienced, and verifiable through investigation.
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.
Dr. Williams would like to assess the effects of meditation (Daily, 3x weekly, or none) and exercise (1x weekly, 3x weekly, or 5x weekly) on depression scores among a sample of 300 young adults.
She randomly assigns participants to the above conditions.
1.) What is the factor notation? 2.) What type of data analysis would she use to answer the research question?
1.) 3 x 3
2.) Factorial Anova
You receive the following results from a t-test: Test value=4
t=25.87
df=450
sig=.031
Report this in apa style.(I.e t and p value) Is this test significant?
t(449)=25.87, p< .05. Yes, it is significant
