Question 1: Survey construction

Attached is a copy of a past Childcare survey that SUSB sent to all students, faculty, and staff.  Pretend that the committee came to you with this survey as a draft and asked you for your feedback.  Provide 5 specific suggestions for them to improve their survey.  If you don't think I'll understand why your suggestion would be useful, include a 1-2 sentence explanation. Label these suggestions A, B, C, D, and E so I can easily see your suggestions.  The survey would be given online so don't comment on the spacing. 

Question 2: Levels of Variables

In the childcare study state the level of variable (binary, nominal, ordinal, interval, and ratio) for the listed survey questions.  Provide a one sentence justification for each. 

The survey does not use a Likert scale.  What would be the level of variable for a Likert scale.

Question 3: Qualitative study

The Childcare survey is mostly quantitative. Write a paragraph describing how you might qualitatively gather data to do a "preliminary exploration of possible childcare options." You do not have to use a survey like this one as part of your method.

Question 4: Factorial Studies

If you have a study that is a 2x3x2 factorial

A) How many independent variables are there?

B) How many levels for each independent variable?

C) How many conditions are there?

D) How many potential main effects are there to examine?

E) What is the level of variable (binary, nominal, ordinal, interval, ratio) that is represented by the first 2 in the 2x3x2 factorial?

Bonus question: Construct a 2x2 factorial table that has no significant main effects but has a significant interaction.

Question 5: Between/within studies

A) Define the terms between-participants study and within-participants study.

B) State an advantage of between-participant study.

C) State an advantage of a within-participant study.

D) Why is random assignment to conditions not appropriate for a within-participant study?

E) For the 2x3x2 factorial study in the previous question, do we know which variables are between and which variables are within?

Question 6: Quasi-experiment

A) This question uses the attached Pasto and Baker (2001) study.  In 1-2 sentences describe why the Pasto and Baker study is a quasi-experiment.

B) Recently President-Elect Trump mentioned that he would in the first year deport 2-3 million illegal immigrants, with the implication that this is a large number for deportation.  Only having this information mimics a poor quasi-experimental design.  What is another piece of information that is needed to know if 2 to 3 million is a high number?

B) Evaluate the internal validity of the Pasto and Baker study.

Bonus question: Make a specific, practical suggestion that would improve the internal validity of the Pasto and Baker study. (1-3 sentences)

Question 7: Experiment

The Pasto and Baker (2011) study is a quasi-experimental design.  In a paragraph describe how you could do a true experiment that is a conceptual replication of this study.  Remember as this is a conceptual replication, the study could look very different; it just needs to test the same hypothesis.

Question 8: Central Tendency

A) Which of the three measures of central tendency (mean, median, mode) can you use with nominal data?

B) Which measure of central tendency is most affected by outliers?

C) Can a measure of central tendency ever be below 0?  If yes, provide a small dataset (e.g., n=3) that has the mean less than 0. 

D) If you were a server at a restaurant and you wanted to find the central tendency of the percentage tip (e.g., 20%) you received, which measure of central tendency would you use?  Defend your answer in 1-2 sentences.
