FINAL JEOPARDY

• ANSWER This is why we need ANOVA with more than
  two groups (AKA why we cant just run multiple
  t-tests to make all of the comparisons between
  groups).
• QUESTION What is because it controls for rising
  a, a inflation, or increases familywise error
  rate?

3
One-way ANOVA100

• ANSWER For ANOVA, these will always be the null
  and alternative hypotheses respectively.
• QUESTION What is H0 all of the means are equal
  (or µ1 µ2 µ3 µk) HA all of the means are
  not equal?

4
One-way ANOVA200

• ANSWER This is the conclusion that you would
  draw and what your next step would be.
• QUESTION What is conclude that there are
  differences among the groups (reject H0) and look
  at multiple comparisons table to see which groups
  are significantly different from one another.

5
One-way ANOVA300

• ANSWER This would be my next step if got this
  SPSS output for a one-way ANOVA.
• QUESTION What is STOP and conclude that there
  are no differences among the groups (AKA retain
  H0)?

6
One-way ANOVA400

• ANSWER This is the prerequisite that must be met
  before looking at the results of following table.
• QUESTION What is the F test in the ANOVA table
  has to be significant (p lt .05).

7
One-way ANOVA500

• ANSWER Assuming F is significant, there would be
  significant differences between the following
  groups.
• QUESTION What is students who study an average
  of 1-3 hours/week and those who study 3-6 hrs/wk
  and 1-3 and 3-6 hrs/wk?

8
Correlation Regression 100

• ANSWER This is Pearsons r.
• QUESTION What is r .04 (.035)?

9
Correlation Regression 200

• ANSWER You look at the correlation between
  average hrs/wk students spend in the library and
  average hrs/wk in the gym, and r -.52. This
  would be your interpretation.
• QUESTION What is this is a moderately strong
  negative correlation, as amount of time spent in
  library goes up, rec goes down and vice versa?

10
Correlation Regression 300

• ANSWER You think that satisfaction with Miamis
  IT services will predict satisfaction with the
  library resources available on campus. In a
  regression, this would be your IV and DV
  respectively.
• QUESTION What is IV IT services and DV
  Library resources?

11
Correlation Regression 400

• ANSWER You do a regression predicting
  perceptions that Miami courses are rigorous from
  satisfaction with library resources. The slope,
  intercept and regression equation would be the
  following.
• QUESTION What is slope .46, intercept 3.86,
  equation is Y .46X 3.86?

12
Correlation Regression 500

• ANSWER You do a regression predicting
  perceptions that Miami courses are rigorous from
  satisfaction with library resources and obtain
  the following equation Y .46X 3.86. This is
  how you would interpret the slope.
• QUESTION What is for every one-unit increase
  decrease in satisfaction with library
  resources, there will be a 0.46 increase
  decrease in the perception that Miami courses
  are rigorous.

13
Plots and Graphs100

• ANSWER In two-way ANOVA, a plot where the lines
  on the graph are not parallel indicates this.
• QUESTION What is an interaction?

14
Plots and Graphs200

• ANSWER The effects shown in this plot.
• QUESTION What is a main effect of both gender
  and class rank with NO interaction?

15
Plots and Graphs300

• ANSWER These are the effects shown in this plot.
• QUESTION What is two main effects and an
  interaction?

16
Plots and Graphs400

• ANSWER The types of effects you see in this
  plot.
• QUESTION What is a main effect of Greek
  involvement only?

17
Plots and Graphs500

• ANSWER The type of relation depicted here (Hint
  think correlation)
• QUESTION What is a negative correlation or
  relation?

18
Factorial ANOVA100

• ANSWER This is the effect of just one of your
  factors collapsing across and ignoring the levels
  of the other factor.
• QUESTION What is a main effect?

19
Factorial ANOVA200

• ANSWER When the effect of one of your factors is
  different across the levels of another factor,
  this type of relationship is said to exist.
• QUESTION What is an interaction?

20
Factorial ANOVA300

• ANSWER You one a two-way ANOVA and get the
  following results. These are the effects that are
  significant.
• QUESTION What is both main effects but NOT the
  interaction?

21
Factorial ANOVA400

• ANSWER You perform a 2(gender) 4(class rank)
  ANOVA. These are the variable(s) that require
  post hoc tests.
• QUESTION What is class rank?

22
Factorial ANOVA500

• ANSWER When the interaction is not significant
  (p gt .05) your interpretation should focus on
  this.
• QUESTION What are the significant main effects.

23
Hodgepodge100

• ANSWER This is the purpose of post hoc tests
  (e.g., Fishers LSD, Tukeys HSD).
• QUESTION What is they enable us to identify
  specific differences between 3 or more groups
  without raising a?

24
Hodgepodge200

• ANSWER In two-way ANOVA, the circumstance under
  which you run post hoc tests for a factor.
• QUESTION What is when the factor consists of
  more than 2 groups or levels)?

25
Hodgepodge300

• ANSWER This is what it means to say have a 3 2
  design.
• QUESTION What is we have two factors with three
  groups or levels of the first factor and 2 groups
  or levels of the second factor?

26
Hodgepodge400

• ANSWER A researcher using math SAT scores
  (pre-admittance) to predict students subsequent
  grades in college math classes. This is my IV and
  DV.
• QUESTION What is my IVSAT scores and my DV
  grades in college math classes.

27
Hodgepodge500

• ANSWER If X is the IV (satisfaction with Miami
  libraries) and Y is the DV (rated rigor of Miami
  courses), this would be the predicted value of y
  when X 4.23 Y .46X 3.86.
• QUESTION What is Y .46(4.23) 3.86 5.81?
