100
In what section(s) are the participants described in detail?
Methods, and briefly in abstract
100
What is Internal Validity?
When researchers want to find a relationship among their IV and DV such that the manipulation of the IV causes the change in the DV
100
In order to be considered an experimental design a study must include what components? Explain the components as well.
IV- manipulated variable DV- measured variable Random assignment- participants have equal chance of being in each condition
100
Write a stem item/question for a nominal scale of measurement.
Answers will vary.
100
Draw a positively skewed distribution.
Peak to the far left and tail on the right
200
Correct the following citation according to APA guidelines. Fox, J., Ralston, R., Cooper, C., Jones, K. (2015). "Sexualized Avatars Lead to Women's Self-objectification and Acceptance of Rape Myths." Pyschology of Women Quarterly, 39(3), 349-362.

What is External validity
When researchers want to apply their findings to other populations
200
Name and explain two ways to ensure your study is ethical.
Answers will vary.
200
Write a stem for the following response... 1-Strongly agree 2-agree 3-neither agree or disagree 4-disagree 5-strongly disagree
Answers will vary

A bell curve is what type of distribution? What measure of central tendency and variability should you report for this type of distribution?
Normal Mean and standard deviation
300
Where should you write about the participants in your study and what information about them should be included?
"Methods" section in the subsection labeled "Participants." Include demographic information (age, race, gender), how participants were obtained, and relevant information about participants.
300
What is Alternate/Equivalent forms reliability?
Participants complete two different measures that are testing the same concept and they score similarly for both
300
Xanadu wants to study how different types of music effect people's mood. In order to study this experimentally what would be the IV and the DV?
IV- Music DV-Mood
300
Jennifer asks her participants to rank their favorite beverage from 1-5 with 1 being the high. Soda, Juice, Water, Beer, Wine What scale of measurement is this?
Ordinal (ranking)
300
Why do we use descriptive statistics?
Quantitatively (numerically) summarize the sample
400
How is the results section unique from most other sections in a primary research article (introduction, method, discussion, etc.).
The most technical section of the article. Provides the results of analyses (and statistics) used to test the hypothesis. No citations.
400
What is construct validity?
The items in your measure are getting at the concept of what you're trying to measure
400
In Xanadu's experiment she manipulates the type of music her participants listen to and measures their mood. Come up with 5 levels of the IV for this experiment.
Answers may vary. Rock, Blues, Jazz, Classical, & no music.
400
If each question on an exam is worth 5 points what is the scale of measurement?
Ratio (True zero)
400
Explain standard devation
Describes the degree to which scores differ from the mean
500
List the components of a method section
Participants Measures Procedure
500
Explain split-half reliability. What does this assess about the study?
Correlation between even and responses (NOT 1st HALF 2nd HALF). Assesses the internal consistency of the scale.
500
In Xanadu's experiment where type of music is manipulated and mood is measured, how would you operationally define the IV?
Answers will vary. For example, listen to assigned genre of music for 10 minutes using headphones.
500
Why is it important to identify the scale of measurement?
In order to choose the most appropriate analysis
500
What measure of central tendency should be used for skewed distributions? Why?
Median To control for outliers
