Question 1

Calculate the range of the following raw responses: 2, 3, 3, 4, 5, 5, 6, 6, 6, 7, and 8.

Accepted Answer

The range is calculated by subtracting the smallest value in the set from the largest value. Here, the smallest value is 2 and the largest is 8, so the range is 8 - 2 = 6.

Question 2

When information is obtained from internal data warehouses, it must be checked for availability, consistency, correct format, and so on.

Accepted Answer

It is important to perform data quality checks on information obtained from internal data warehouses to ensure its accuracy and integrity. This includes verifying its availability, consistency, format, and other factors that may impact its usefulness for decision making or analysis.

Question 3

If an optical scanning approach is used to enter data, assigning a coded value to each response is absolutely necessary to avoid problems in the data entry phase.

Accepted Answer

Optical scanning for data entry often involves recognizing marks or characters directly without the need for manually assigning coded values to each response, as the scanning software can automatically interpret and digitize the information.

Question 4

Which of the following measures requires that the responses be first arranged in a hierarchical pattern?

Accepted Answer

The median is the measure of central tendency that requires the responses to be arranged in a hierarchical pattern, where the values are listed in order from smallest to largest. The median is the middle value in the list or the average of the two middle values if there is an even number of responses. The other measures (average, mean, mode, and standard deviation) do not require hierarchical arrangement of responses.

Question 5

Some data col­lection methods require activities in all stages, while other methods involve only limited data preparation.

Accepted Answer

Some data collection methods, such as surveys or experiments, require activities in all stages, including planning, data preparation, data collection, analysis, and reporting. Other methods, such as observation or document analysis, may involve limited data preparation and focus more on the data collection stage.

Question 6

In the process of editing responses to open-ended questions, researchers typically fill out the incomplete answers based on their best judgment.

Accepted Answer

Researchers should not fill out incomplete answers based on their judgment; they should either code the response as incomplete or follow up with the respondent for clarification, to maintain the integrity of the data.

Question 7

The most recommended approach to dealing with missing data is to use the mean of the entire sample that answered the question as a replacement value.

Accepted Answer

Using the mean of the entire sample as a replacement value is not always the most recommended approach for dealing with missing data. Other methods, such as imputation or multiple imputation, may be more appropriate depending on the nature and extent of the missing data.

Question 8

The objective of the coding process is to expand the number of individual responses to a larger set of specific, yet related categories of answers that can be assigned numerical codes.

Accepted Answer

The objective of the coding process is to organize and categorize text or responses into smaller, manageable groups with similar meanings that can be easily analyzed, not to expand the number of individual responses.

Question 9

Developing consolidated categories is a subjective decision.

Accepted Answer

Developing consolidated categories involves grouping and categorizing information based on similarities, which can be subjective and open to interpretation. Different people may have different criteria for creating categories and may group items differently, making it a subjective decision.

Question 10

Which of the following measures is an indicator of how similar or dissimilar the numbers are in a set of responses?

Accepted Answer

Standard deviation measures the amount of variation or spread in a set of data. A larger standard deviation indicates more variability or dissimilarity among the numbers in the set, while a smaller standard deviation indicates less variability or similarity. Therefore, E is the best choice as an indicator of how similar or dissimilar the numbers are in a set of responses.

Question 11

A coded value can be rejected if it is too large or too small for a particular scaled item on a questionnaire.

Accepted Answer

This is true. Coded values need to fit within the range of possible responses for a particular question on a questionnaire. If a coded value is too large or too small, it may be rejected as an invalid response.

Question 12

Missing data may occur when a respondent simply does not see a question, or is in a hurry to complete the survey and simply skips a question.

Accepted Answer

This is a common reason for missing data in surveys.

Question 13

Data is validated using the curbstoning process.

Accepted Answer

Curbstoning is a fraudulent activity where an individual poses as a private seller but is actually selling cars as a business without proper licenses and registrations. It has nothing to do with data validation.

Question 14

Scanning technology cannot be used to enter data.

Accepted Answer

Scanning technology, such as barcode scanners or optical character recognition (OCR) scanners, can be used to enter data into a system.

Question 15

Codes must be assigned to facilitate quantitative data analysis only after responses are reviewed and themes and common words and patterns are identified.

Accepted Answer

Codes should only be assigned after a thorough review of the data to identify common themes, words, and patterns. This helps to ensure that the codes accurately represent the data and facilitate accurate quantitative data analysis.

Question 16

With traditional data collection methods, the data preparation process starts before the interviews, questionnaires, or observation forms have been completed and returned to the field supervisor or researcher.

Accepted Answer

Data preparation typically begins after data collection is completed, as it involves organizing, cleaning, and processing the collected data for analysis.

Question 17

The simple process of counting the number of observations (cases) that are classified into certain categories is known as _____.

Accepted Answer

Tabulation is the process of counting the number of observations that are classified into certain categories. Editing refers to ensuring the accuracy and completeness of data. Screening refers to the process of removing irrelevant information. Validation refers to checking the accuracy of data entered into the system. Data entry refers to the process of entering data into a system.

Question 18

Calculate the mode of the following raw responses: 2, 3, 3, 4, 5, 5, 6, 6, 6, 7, and 8.

Accepted Answer

The mode is the value that appears most frequently in the set of data. In this case, the number 6 appears three times, which is more than any other number in the set. Therefore, the mode is 6.

Question 19

Cross-tabulation is most often used with nominal or ordinal scaled data.

Accepted Answer

Cross-tabulation is generally used with nominal or ordinal scaled data.

Question 20

A one-way frequency table shows the number of respondents who answered each possible response to a question given the available alternatives.

Accepted Answer

A one-way frequency table does indeed show the number of respondents who gave each possible response to a question from a set of alternatives.
