Question 1

The book that contains a list of all the variable names and the code numbers associated with each possible response to each question is called the "data set."

Accepted Answer

The book that contains a list of all variable names and their respective codes is called a "codebook." The "data set" is the actual collection of data obtained from the survey or study.

Question 2

Research must adopt a decision rule for determining how many and which item omissions invalidate a survey or a particular question.

Accepted Answer

Yes, research must adopt a decision rule for determining how many and which item omissions invalidate a survey or a particular question. This decision rule is usually based on the extent to which missing data affects the accuracy and validity of the study findings.

Question 3

Refusal to participate may be due to something as simple as the potential respondent is too busy.

Accepted Answer

This statement is true. Refusal to participate can indeed be due to a variety of reasons, including being too busy or having other commitments.

Question 4

"A total of 74% of the respondents used a credit card in the past month," can be described as a descriptive measure of central tendency for metric data.

Accepted Answer

A percentage is not a measure of central tendency; it is a descriptive statistic that summarizes the proportion of a sample with a particular characteristic. Measures of central tendency include mean, median, and mode.

Question 5

In the case of web-based surveys, the code book is vital as it is the researcher's only map to decipher the numbers found in the data file and to match them to the answers to the questions on the questionnaire.

Accepted Answer

The statement is correct. The codebook provides information on how the data variables were coded and how they correspond to the questions asked in the questionnaire. It is essential for the researcher to have a clear understanding of the coding system to accurately interpret the results of the survey.

Question 6

A good definition for a completed interview is one that has all primary questions were answered.

Accepted Answer

A completed interview is one where all primary questions have been answered.

Question 7

A research study determined that a company's expenditure in training was related to sales force performance. This is an example of relationship analysis.

Accepted Answer

Relationship analysis involves examining the associations between variables or factors, and determining whether they are related or not. In this example, the company's expenditure in training is one variable, while the sales force performance is another variable, and the research study found that there is a relationship or association between the two variables. Therefore, this is an example of relationship analysis.

Question 8

Nonresponse is composed of refusal and item omission; break-offs are a separate issue.

Accepted Answer

The answer of Nonresponse is composed of refusal and item...

Question 9

Data entry refers to the creation of a computer file that holds the raw data taken from all the completed questionnaires.

Accepted Answer

Data entry refers to the process of entering data into a computer file, and in this case, it specifically refers to the creation of a file from completed questionnaires.

Question 10

When a researcher identifies a categorical variable and compares the groups represented by that variable by analyzing their differences with the second variable, it is referred to as bimodal analysis.

Accepted Answer

Bimodal analysis refers to analyzing data with two distinct peaks or modes, usually in a histogram. It is not related to the comparison of groups represented by a categorical variable with a second variable.

Question 11

An item omission refers to the failure to include an important question on a survey questionnaire which may seriously threaten the achievement of the research objectives.

Accepted Answer

The answer of An item omission refers to the failure...

Question 12

Data entry requires the researcher to first undertake an operation called data coding.

Accepted Answer

Data coding involves assigning numerical codes or labels to raw data to make it easier to analyze and input into a database. This is an important step in the data entry process.

Question 13

Regression analysis is the most complex and provides the greatest value to the client.

Accepted Answer

The answer of Regression analysis is the most complex and...

Question 14

The complementary processes of data coding and data entry result in data analysis.

Accepted Answer

Data coding involves assigning labels or codes to the data for categorization and organization, while data entry involves inputting the data into a computer or database. Data analysis involves interpreting and drawing conclusions from the data. While coding and entry may be necessary steps in preparing the data for analysis, they themselves do not directly result in data analysis.

Question 15

The level of measurement dictates the proper data analysis.

Accepted Answer

The level of measurement determines which statistical tests or methods are appropriate for analyzing the data. For example, nominal data (categorical data with no numerical value) can be analyzed using frequency analysis or chi-square tests, while interval or ratio data (numerical data) can be analyzed using measures of central tendency, correlation analysis, or regression analysis.

Question 16

A completed interview is always defined as an interview in which 100 percent of the questions have been answered.

Accepted Answer

A completed interview may not require 100% of questions to be answered, as some questions may be optional or not applicable.

Question 17

Nonresponse has been labeled the marketing research industry's biggest problem.

Accepted Answer

Nonresponse, which refers to the failure of some people to participate in a survey or study, is a significant challenge in marketing research, as it can lead to biased results and decreased representativeness of the sample.

Question 18

In most data analysis situations with in XL Data Analyst, the code book information will be input to the data file so that analysis program can access it and apply it to whatever analysis is being performed.

Accepted Answer

Inputting code book information to the data file allows the analysis program to access and apply it to the analysis being performed.

Question 19

Multiple submissions is the only data collection error that is not unique to online surveys.

Accepted Answer

Multiple submissions can occur in both online and offline surveys, but it is not the only data collection error that can occur in both. Other errors, such as misinterpretation of questions or data entry mistakes, can also happen in both online and offline settings.

Question 20

Some industry observers believe that nonresponse is caused by fears of invasion of privacy, skepticism of consumers regarding the benefits of participating in research, and the use of research as a guise for telemarketing.

Accepted Answer

These are some of the common reasons cited by industry observers for nonresponse rates in research.
