Researchers for a local fitness center sent a survey to its members. One question asked, "How many times per month do you visit the gym?" One of the respondents answered, "twice a week."

editing

Before analyzing data, researchers must address item nonresponse. All of the following are possible strategies except ____. a. contact the respondent again b. eliminate the missing item from all surveys c. eliminate the case with the missing item only in analyses using the variable d. eliminate the case with the missing item(s) from all further analyses

What is true about the editing process for data? a. Editing is primarily a concern for observation-based studies. b. Editing involves the analysis of data. c. The basic purpose of editing is to make certain that raw data meets minimum quality standards. d. Editing does not involve the correction of data

The basic purpose of editing is to make certain that raw data meets minimum quality standards.

If a question on a survey is a "check all that apply" item with 7 answer choices, the best way to code it would be to ____. a. assign a "0" for answer choices not selected and a "1" to each answer choice selected b. use a single variable coded 1 through 7 c. create a numerical code for each combination of possible answers d. code the actual response

assign a "0" for answer choices not selected and a "1" to each answer choice selected

Anupam is cleaning data for a research project he is working on. One of the questions asks respondents to identify the month in which they were born. Anupam assigned numerical codes 1 through 12 for each month, with 1 being for January, 2 for February, and so on. Upon looking at the responses, he notices a few "13" responses. He knows there is not a 13th month, so this must be a ____. a. blunder b. missing code c. response error d. double-entry

blunder
