Question 1

Although it is preferred,there does not have to be a variable label,or a unique,short,single-word description for that variable placed in the first row on the Data worksheet.

Accepted Answer

It is preferred to have a variable label, or a unique, short, single-word description for that variable placed in the first row on the Data worksheet.

Question 2

One of the reasons your authors created the XL Data Analyst is because practically everyone is familiar with Excel.

Accepted Answer

The statement is correct that one of the reasons behind creating the XL Data Analyst is because almost everyone is familiar with Excel. This can result in easier adoption and understanding of the tool.

Question 3

Practically all statistical analysis programs treat a "blank" as "missing data."

Accepted Answer

Most statistical analysis software treats blank values as missing data. This is because blank values indicate a lack of data for a particular variable or observation, which can affect the accuracy of statistical analyses.

Question 4

Adding a variable in the middle of a data set means that a new column will be created in the Data worksheet,and the Data-Define Variable link will become misaligned.

Accepted Answer

Adding a variable in the middle of a data set means that the subsequent variables will shift to the right, and a new column will be created in the location of the inserted variable. This will cause the Data-Define Variable link to become misaligned.

Question 5

The use of value codes and value labels depends on the nature of the variable.

Accepted Answer

Value codes and value labels are used to represent the values of a variable in a more understandable format. The use of value codes and labels is dependent on the nature of the variable, such as its data type and the purpose it serves. Therefore, the statement is true.

Question 6

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 matrix register."

Accepted Answer

The book that contains a list of all the variable names and the code numbers associated with each possible response to each question is actually called the "codebook" or the "data dictionary." The "data matrix register" is not a commonly used term in the field of data analysis.

Question 7

A variable description is limited to one word.

Accepted Answer

A variable description can range from one word to a few words, depending on the level of detail needed to accurately describe the variable.

Question 8

To return to the original data set after using a selected subset for analysis,simply use the Utilities-Unfilter Data operation.

Accepted Answer

The "Unfilter Data" operation will remove any filtering or subsets that were applied to the original data set, restoring it to its original state.

Question 9

The Data worksheet is linked to the Data Variables worksheet by: Copy-Paste Special-Paste Link.

Accepted Answer

The question accurately describes how to link two worksheets in Excel using the Paste Link option which creates a dynamic connection between the cells.

Question 10

A completed questionnaire is not left up to the judgment of the researcher; completed means that all questions have been completed.

Accepted Answer

A completed questionnaire is typically defined as one where all required questions have been answered, but it may still be subject to the researcher's judgment regarding the quality and relevance of the responses.

Question 11

Break-offs,item omissions,and problem respondents are uncommon in the industry.

Accepted Answer

Break-offs, item omissions, and problem respondents are common issues in survey research, particularly in larger-scale studies. These issues can impact the data quality and accuracy of the results, so researchers must take steps to minimize their occurrence and address them appropriately when they do occur.

Question 12

Creating a computer file that holds the raw data from all the completed surveys is called data entry.

Accepted Answer

This statement is true. Data entry involves inputting raw data into a computer file, such as the data collected from completed surveys.

Question 13

There are two named worksheets in an XL Data Analyst that are critical: the Data worksheet and the Define Variables worksheet.

Accepted Answer

The Data worksheet contains the actual data and the Define Variables worksheet lists the variables in the data and their definitions. Both of these worksheets are important for data analysis.

Question 14

A variable description is a phrase or sentence that identifies the variable in more detail and refers to the question on the questionnaire.

Accepted Answer

This is true. A variable description provides additional information about a variable, such as its scale, units of measurement, or what it represents, and typically refers back to the question or item that it is measuring on the survey or questionnaire.

Question 15

The XL Data Analyst produces tables that can be copied and pasted into word processor applications such as Microsoft Word without the need for extensive reformatting into professionally appearing tables.

Accepted Answer

The statement is true. XL Data Analyst produces tables that are formatted in a professional and neat way, making it easy for users to copy and paste them into word processor applications such as Microsoft Word without the need for extensive reformatting.

Question 16

The way you set up your code book in XL Data Analyst is through the Define Variables worksheet.

Accepted Answer

This statement is true. The Define Variables worksheet in XL Data Analyst is used to set up the code book for your dataset. It allows you to define the variable names, data types, measurement levels, and value labels.
