You are conducting a study of students doing work-study jobs on your campus. Among the questions on the survey on the instrument are:
A. How many hours are you scheduled to work each week? Answer to the nearest hour.
B. How applicable is this work experience to your future employment goals?
Respond using the following scale: 1 = not at all, 2 = somewhat, 3 =very
Be sure to label the question you are working on:
a. Suppose you take random samples from the following groups: freshman, sophomores, juniors, and seniors. What type of sampling technique was used?
b. Describe the individuals of the study.
c. What is the variable for question A? What type of variable is it (quantitative or qualitative)? What is the level of measurement?
d. What is the variable for question B? What type of variable is it (quantitative or qualitative)? What is the level of measurement?
e. Is the proportion of responses “3=very” to question B a statistic or a parameter?
f. Suppose only 40% of the students you selected for the sample respond. What is the nonresponse rate? Do you think the nonresponse rate might introduce bias into the study? Explain.
g. Would it be appropriate to generalize the results of your study to all work-study students in the nation? Explain.
