Exam 11: Analyzing and Interpreting Data for Decisions

The mode is the measure of central tendency used with nominal data.

It is not possible to compute the response that separates the top half of response frequencies from the bottom half for nominal data.

For nominal data, the measure(s) of central tendency and dispersion that can be computed is(are)

In terms of frequency distributions and percentages, if respondents are asked to "check all that apply" then the percentages reported in the tables

It is standard operating procedure for marketing research firms using phone or personal interviewers to push for ""do not know"" or ""no opinion"" responses.

Which of the following is (are) a useful measure(s) of central tendency and dispersion when the data are ratio?

The standard deviation tells us the range of answers that includes roughly ____ percent of the sampled respondents.

It is possible to compute the response that separates the top half of response frequencies from the bottom half for nominal data.

It is not possible to set up three-way cross-tabulations.

The average of the responses computed by summing all responses and dividing by the number of responses is the mean.

It is customary to have the banner headings consist of independent variables.

Standard deviation can be used for both nominal and interval data analysis.

Data analysis is a value-adding activity.

The most important outcome of the data analysis process is

Each row of data in a table represents a "data bit."

Attempting to cross every survey question with all the variables should be resisted in data analysis situations.

The standard deviation represents the degree of spread of responses among the response categories.

The standard deviation tells us the range of answers that includes approximately 90% of the sampled respondents.

In terms of frequency distributions and percentages,

Which of the following is (are) a useful measure(s) of central tendency and dispersion when the data are interval?
