b. choosing an appropriate statistical test
c. specifying the significance level for the test
d. determining the probability of the test statistic under the null hypothesis
e. all of the above are steps in the typical hypothesis testing procedure
Which of the following is TRUE?
a. An advantage of scales is that a great deal of information can be secured from the
respondent in a short period of time.
b. Item nonresponse is the group of respondents who refuse to participate in the survey
being conducted.
c. Once a good set of questions has been developed, it is of little consequence as to the

A researcher determined the size sample necessary to estimate two population means Y
and Z. The indicated sizes were 200 to estimate Y and 300 to estimate Z with the
specified degrees of confidence and precision. The researcher decided therefore to use a
sample of size 250. Assuming the estimates of the population standard deviation were
correct if
a. the estimate of Y is more precise than desired while that for Z is less precise than
desired.
b. the estimate of Y is less precise than desired while that for Z is more precise than
desired.
c. Y is estimated with exactly the specified degree of precision while Z is estimated less
precisely than desired.
d. Z is estimated with exactly the specified degree of precision while Y is estimated less
precisely than desired.
e. Both Y and Z are estimated with the exact specified degree of precision.
The advantages of stratified over simple random sampling include
a. stratified sampling ensures adequate representation from each stratum of interest.
b. stratified sampling can produce more precise sample statistics.
c. stratified sampling allows for the comparison of variables between strata.
d. b and c.
e. all of the above.

weight of adult males. Calculate the index of predictive association.

b. 0.44

Which of the following about nominal data is TRUE?
a. Possible operations with nominal scales are few, but due to the fact that the properties
of "greater than" or "less than" apply, the addition of numbers is permissible.
b. The median is an appropriate measure of central tendency with nominal data.
c. A nominal scale is associated with the concept of order.
d. Computing the median is an unacceptable statistical operation when one is dealing
with nominal data.
e. They are all false.
The BEST way to handle missing items when analyzing the data is to:
a. leave the item blank and report the number blank as a separate category
b. eliminate the case with the missing item in analyses using the variable
c. substitute values for the missing item
d. a and b
e. there is no single best way for handling missing items but rather their treatment
depends on the purpose of the study, the incidence of missing items, and the methods
that will be used to analyze the data
Which of the following is FALSE?
a. The field edit is primarily designed to detect the most glaring errors and omissions.
b. The only purpose of the field edit is to check the questionnaires or observational
forms for completeness.
c. The purpose of analysis is to generate meaning from the collected data.
d. Editing involves the inspection and correction, if necessary, of each questionnaire or
observation form.
e. The central office edit depends less on follow-up and more on deciding explicitly
what to do with the data.

d. large; binominally
e. none of the above
Which of the following is FALSE?
