Exam 13: Data Processing, Data Analysis, and Statistical Testing

The first step in the data analysis process is coding.

Which of the following is not a measure of dispersion?

Error checking routines and marginal reports are part of which of the following processes?

The purpose of the first edit, or field edit, is to identify problems when there is still time to recontact the respondent and determine the appropriate answer to questions that were not asked.

Cross tabulations look at differences in mean values.

Checking to determine whether the proper screener questions were invoked would be part of which step in the data analysis procedure?

Charting the answers to open-ended questions is standard.

Open-ended questions are often necessary even in surveys whose major objective is to produce quantitative data. Given the open-ended responses below, how would you summarize them for analytical purposes? QUESTION: How do you think the taste of Pepsi compares with Coca Cola? Responses: The taste of Pepsi was 1) Better 2) Sweeter 3) Too sweet 4) Not as refreshing 5) More refreshing 6) Sweeter is better 7) Bolder taste 8) They taste about the same 9) I don't know 10) I don't have any idea 11) I don't drink soft drinks 12) Soft drinks are not good for you 13) Sweeter is better 14) Not a refreshing as Coca Cola 15) Coca Cola has always been my favorite brand

Which type of analysis cannot be computed with nominal data?

Categorical data is typically analyzed with percentages rather than means.

____________ is the process of grouping and assigning numeric codes to the various responses to a question.

Assigning numeric codes to various responses is called tabulating.

Checking to ensure that skip patterns were followed occurs during the data editing stage.

The median is always equal to the mean.

With one-way frequency tables, the base size for a question would not take into consideration:

Open-ended questions are tabulated on a point system.

The idea behind this type of statistical analysis is to look at the responses to one question in relation to the responses to one or more other questions.

The median can be computed for all types of data except nominal data.

Means are not included in a cross tabulation.

This measure of central tendency can be computed only from interval or ratio data.
