Complete this APA statement for this one-way ANOVA output in SPSS:
F( , )=___, p_____
We do (retain/reject) the null hypothesis.
F(2,27)= 4.46, p<.05. We reject the null hypothesis.

Proportion of variance accounted for is indicated by this symbol.
Hint: Be specific!
What is R2.

Whether or not the audience has an effect on individuals depends on levels of the ______ factor. This is called a _______ effect.
What is self esteem?
What is an interaction effect?

Overall, these groups had higher scores for each variable?

One possible reason for why birds migrate and others maintain year round residency in a single location is intelligence. Specifically, birds with small brains, relative to their body size, are simply not smart enough to find food during the winter and must migrate to warmer climates where food is easily available (Sol et al., 2005). Birds with bigger brains, on the other had, are more creative and can find food even when the weather turns harsh. Use this kind of test to compare brain sizes across three samples of birds: Non-Migrating, Short-Distance Migrants, and Long-Distance Migrants.
What is a one-way ANOVA?

Sales figures show a positive relationship between temperature and ice cream consumption; as temperature increases, ice cream consumption also increases. You find that when temperature increases, both ice cream consumption and crime rates tend to increase. Use this kind of analysis to determine the true relationship between ice cream consumption and crime rate.
What is correlation?
200
True or False: According to this Bonferroni comparisions output, all group means ( Under 40; 40-59; and 60 and over) are significantly different from each other at the .05 level.
What is true?

For Result B we find: 
What is an interaction effect?
No main effects.
200
When reviewing this fictitious graph for effects we find this group had the most pounds lost and this group had the least
What is the Exercise Yes and Diet Yes group?
What is the Exercise Yes and Diet No group?

A pharmaceutical company has developed a drug that is expected to reduce hunger. To test the drug, two samples of rats are selected with n=20 in each sample. The rats in the first sample receive the drug every day and those in the second sample are given the placebo. The dependent variable is the amount of food eaten by each rat over a 1-month period.
BOTH of these hypothesis tests could help us determine significant differences between these two groups.
What are:
t-test for independent samples &
one-way ANOVA?

Participants in a study on delayed discounting in were asked how much they would take today instead of waiting for a specific delay period to receive $1,000. Each participant responds at 1 month and 6 months.
Use this kind of hypothesis test to determine whether there are significant differences among the different delay periods.
What is a repeated measures t-test?

Based on this SPSS output for a t-test for independent means, you would use this t obtained value. Fill in the blanks here: t( )= ______, p_____
What is -3.656?
t(169.70)= -3.656, p<.001

For Result C, we find:
What is a main effect of task difficulty?
What is a main effect of arousal?
There is no interaction.
300
True or False: There is a main effect of the Exercise condition and the Diet condition.
What is false?
300
1) Use this kind of test to determine homogeneity of variance for two independent samples?
2) Researchers ideally want to (retain/reject) the null hypothesis for this kind of hypothesis test.
You must get both parts correct to score on this question.

The distribution of scores on the SAT is approximately normal with a mean of µ=500 and a population standard deviation is σ=10, what score would someone need to end up in the top 40%?

This degrees of freedom is reported for all three hypotheses investigated in this two-way ANOVA:
What is 92? (dfError or dfWithin also accepted)

When looking at Result F, we find that even though there are no main effects of these two variables ____, our results are qualified by an interaction showing a reversal of trends.
What is Task Difficulty?
What is Manipulated Arousal?

Explain these results: 
Those with a low self esteem tend to attribute failures to themselves more than their failures.
However the trend reverses in those with high self-esteem, who tend to attribute successes to themselves more than their failures.
While there are likely no significant main effects of the Success condition (IV1) or Self-Esteem condition (IV2) on Self-attribution (DV), it is important to report the informative interaction.

A developmental psychologist is examining the development of language skills from age 2 to 4. Three different groups of children are obtained, one for each age, with n=16 children in each group. Each child is given a language-skills assessment test. This kind of test would be used to determine mean differences between age groups.
What is a one-way ANOVA?
400
After obtaining a significant result for an omnibus ANOVA for three different groups, you will follow up with this kind of analysis to determine the significant mean differences.
Hint: Just provide the general term.
***Also, know what an omnibus ANOVA is!!!

A store manager says, "how old people are doesn't matter, it's how long they spend in the store." If she said that after seeing the results of one of these, she was most likely looking at this scenario.
What is none of the above?

Explain the results of the graph below. Include any main effects, interactions and care that should be taken when reporting.
(Say something like-->) There is a main effect of Condition and a main effect of Group. However, it should be noted that the scores of Group 1 are drastically increased when in Condition B, compared to Condition A.

A researcher is planning a study comparing Facebook users with non-Facebook users at the middle school, high school and college levels. The results are presented in a matrix of 6 groups. The researcher should use this kind of test to evaluate the mean differences.
Hint: Be VERY specific.

Use this kind of test to determine the effect of Number of Churches (X1) and Population Size (X2) on Number of Crimes (Y).
Hint: The IVs are continuous variables, not nominal.
