Question 1

Responses can be logically inconsistent.

Accepted Answer

Responses can be logically inconsistent if they contradict each other or do not make sense when analyzed together.

Question 2

If possible,standard codes should be used for missing data.

Accepted Answer

Using standard codes for missing data can make it easier to identify and handle missing values during data analysis.

Question 3

When setting up the code book for a questionnaire,you would allow 2 columns to code the response to the question
"Do you have a valid passport? 1.yes 2.no"

Accepted Answer

This question has a binary response (yes or no), so only one column is needed to code the response, with 1 representing "yes" and 2 representing "no".

Question 4

Missing value codes should be distinct from the codes assigned to the legitimate responses.

Accepted Answer

This is important so that missing values are not confused with actual responses and do not cause errors in data analysis.

Question 5

All extreme values result from errors and point to problems with the data.

Accepted Answer

While extreme values can sometimes result from errors, they can also be valid data points that indicate unusual or significant information. Therefore, not all extreme values necessarily indicate problems with the data.

Question 6

The initial step in questionnaire checking involves a check of all questionnaires for completeness and interviewing quality.

Accepted Answer

The initial step in questionnaire checking is to check all questionnaires for completeness and interviewing quality.

Question 7

If quotas or cell group sizes have not been met,additional interviews should be conducted in the underrepresented cells before the data are edited.

Accepted Answer

This is because it is important to have a representative sample that accurately reflects the population being studied. If certain cells are underrepresented, the data may be biased and not accurately represent the population. By conducting additional interviews in those cells, the sample will become more representative and the data will be more reliable.

Question 8

A codebook contains coding instructions and the necessary information about variables in the data set.It guides the coders in their work and helps the researcher to properly identify and locate the variables.

Accepted Answer

The statement is true.

Question 9

The following codes should be included for each respondent: project code,interviewer code,date and time codes,category codes,and validation code.

Accepted Answer

The answer of The following codes should be included for...

Question 10

When entering respondent data into a spreadsheet,each column contains the data for one respondent.

Accepted Answer

Each row typically contains the data for one respondent, while each column contains a specific variable or question in the survey.

Question 11

At the editing stage,the researcher makes a preliminary check for consistency.

Accepted Answer

At the editing stage, one of the tasks is to check for consistency in formatting, style, language, and other elements to ensure that the research paper is coherent and logical in its presentation.

Question 12

The data preparation process begins after the fieldwork is done.

Accepted Answer

Data preparation is a preliminary step in the research process, involving the cleaning and organizing of data before analysis, and can begin as soon as initial data is collected, not necessarily after all fieldwork is done.

Question 13

Scanning of questionnaires has allowed Princess Cruises to increase the accuracy of their survey results.

Accepted Answer

Scanning of questionnaires allows for computerized processing of data, which reduces the likelihood of human error and increases accuracy.

Question 14

Unsatisfactory respondents may differ from satisfactory respondents in systematic ways and the decision to designate a respondent as unsatisfactory may be subjective.Both of these factors bias the results.

Accepted Answer

Unsatisfactory respondents may have characteristics or behaviors that are different from satisfactory respondents, which can lead to biased results. Additionally, the decision to classify a respondent as unsatisfactory may be influenced by subjective opinions or interpretations, further contributing to potential bias in the data.

Question 15

Data cleaning includes consistency checks and treatment of missing responses.The checks at this stage are less extensive than the checks made during editing.

Accepted Answer

The answer of Data cleaning includes consistency checks and treatment...

Question 16

Given the time and cost constraints,as well as the fact that experienced keypunch operators are quite accurate,it is sufficient to verify only 15-25 percent of the data entered by keypunching.

Accepted Answer

It is not sufficient to verify only 15-25 percent of the data entered by keypunching. Even experienced keypunch operators can make errors and a higher verification percentage is recommended to ensure data accuracy.

Question 17

Missing responses represent values of a variable that are unknown,either because respondents provided ambiguous answers or their answers were not properly recorded.

Accepted Answer

Missing responses are values that are not recorded, either because the respondent did not provide an answer or the answer was not properly recorded.

Question 18

The selection of data transcription method is guided by the type of interviewing method used and the availability of equipment.

Accepted Answer

The selection of data transcription method is indeed guided by the type of interviewing method used and the availability of equipment.

Question 19

Computer packages like SPSS,SAS,EXCEL,and MINITAB can be programmed to identify out-of-range values for each variable and print related code information to make it easy to check each variable systematically for out-of-range values.

Accepted Answer

True, computer packages like SPSS, SAS, Excel, and Minitab can be programmed to identify out-of-range values for each variable and print related code information to make it easy to check each variable systematically for out-of-range values.

Question 20

The data-preparation process is guided by the preliminary plan of data that was formulated in the research design phase.

Accepted Answer

The preliminary plan of data guides the data-preparation process, which means that it is true that the data-preparation process is guided by the plan formulated in the research design phase.
