For what is the ‘variable view’ in SPSS’s data editor used?
Defining characteristics of variables
Entering data
Viewing output from data analysis
Recoding variables
What does the operation "Recode into different variables" do to the data?
Redistributes a range of values into a new set of categories within an existing variable
Redistributes a range of values into a new set of categories and creates a new variable
Calculates a new variable, such as a total score
Reverses the position of the independent and dependent variable on a graph
In SPSS, what is the "data view"?
A dialog box that allows you to choose a statistical test
A table summarizing the frequencies of data for one variable
A screen in which variables can be defined and labeled
A spreadsheet into which data can be entered
In SPSS, when would you expect to see "values" identified?
When a variable is interval/ratio
When a variable is nominal
When the variable is the dependent variable
When the variable is extraneous
When selecting the measurement type for variables, "scale" refers to what type of data?
Nominal
Ordinal
Interval/Ratio
Scale
When setting up your data in SPSS, how is setup different for between vs. within subjects designs?
In within, the IV is one variable, and the DV is one variable
In between, the variable is each level of the IV and includes the DV score
There is no difference in setup
In between, the IV is one variable and the DV is another variable
What is a one-sample t-test used for?
Comparing means from two related samples
Comparing means from two separate samples
Comparing means from a sample and a population

What type of t-test compares the means for two groups?
Independent Samples
Paired Samples
Dependent Samples
One Sample
Which best describes a t-test?
It is a type of descriptive statistics
It can be used as long as the data is not normally distributed
It is used to determine if there are significant differences between groups

Statistical significance is represented by what letter?
(a)
If my significance value is .015, how would I report the value in my results sentence?
p < .05
p < .01
p < .001
p = .015
If my significance value is .074, how would I report the value in my results sentence?
p < .05
p < .01
p < .001
p = .074
Effect size implies what?
Statistical Significance
How much difference there is between levels of variables
Practical Significance

The variables can be nominal, ordinal, or interval/ratio
The variables will be categorical
There will always be extraneous variables
Dr. B. and Dr. J. are presenting data about proficiency grading at the STP conference in October. They're hoping to demonstrate that students were more likely to pass than using the previous model. In their analysis, what is the IV?
Grading schema
Pass rate
Student grades
Semester
When looking at a mixed ANOVA output, which of the following box titles do we need to pay attention to?
Test of between subjects contrasts
Test of between studies effects
Test of within subjects contrasts
Test of interaction effects
Which of the following is true regarding interaction effects?
If the lines cross, we can automatically assume there is a significant interaction
Interaction effects are more important than main effects
Interaction effects imply that multiple IVs work together to impact the DV
Interaction effects are always found in the output with the between subjects effect
