Question 1

Which type of variable is coded using a 0 for one response and a 1 for the other?
A) Nonmetric
B) Ordinal
C) Interval
D) Dummy
E) Ratio

Accepted Answer

This type of variable is commonly known as a dummy variable or binary variable. It is used to represent a categorical variable with two levels, and is coded as 0 for one level and 1 for the other. An example of this may be gender, where male could be coded as 0 and female as 1.

Question 2

What type of data results from the employment status question?
A) Dichotomous
B) Nominal
C) Ordinal
D) Interval
E) Ratio

Accepted Answer

The employment status question would result in nominal data because the categories are unordered and do not have a numerical value. The options for employment status may include choices such as "employed", "unemployed", "retired", "student", "homemaker", etc. None of these options have a numerical value, so they would be considered nominal data.

Question 3

_____ involves assigning numbers or other symbols to answers so that the responses can be grouped into a limited number of categories.
A) Editing
B) Data entry
C) Coding
D) Measurement
E) Operationalization

Accepted Answer

The process described involves assigning codes to responses, making "coding" the correct answer.

Question 4

In the example,which of the following characteristics of coding rules did the researcher fail to address adequately?
A) Appropriate categories
B) Exhaustive options
C) Mutual exclusivity
D) Single dimension
E) Closed-ended

Accepted Answer

The researcher failed to address mutual exclusivity adequately, as some of the options could have overlapped and led to confusion in the coding process.

Question 5

Allison is editing a data record and finds that a response of 7 has been entered for a question that requests a response between 1 and 5.What should Allison do?
A) Enter a response between 1 and 5
B) Enter a response of unknown
C) Enter a mode for the question
D) Enter a 3 as a neutral response
E) None of the above

Accepted Answer

The answer of Allison is editing a data record and...

Question 6

What type of data results from the vacation question?
A) Interval
B) Nominal
C) Ordinal
D) Ratio

Accepted Answer

The vacation question asks for a category or label, such as "beach vacation" or "mountain vacation," which is a characteristic of nominal data. Nominal data does not have any inherent order or quantitative significance.

Question 7

Which of the following code descriptions is most appropriate for the employment status question?
A) 1 = not employed, 2 = employed part-time, 3 = employed full-time, 4 = full-time student, 5 = other, 9 = missing
B) 1 = checked, 0 = not checked
C) 1 = not employed, full-time student, 2 = employed full-time, 3 = employed part-time, full-time student, 4 = not employed, other, 5 = other
D) All of the above are correct
E) None of the above are correct

Accepted Answer

This code description provides clear categories for different employment statuses, including full-time and part-time employment, full-time student status, and an option for other or missing information. The codes are easy to understand and use consistent numbering for each category.

Question 8

In the example,the use of the response option "other" is used to meet the requirement that categories be _____.
A) appropriate
B) exhaustive
C) mutually exclusive
D) of a single dimension
E) numeric

Accepted Answer

The use of "other" as a response option ensures that the categories are exhaustive, meaning that all possible options are included. The other response option allows for any additional categories that may not fit within the predetermined options.

Question 9

Which number below is frequently used to code missing responses?
A) 0
B) 9
C) 11
D) 100
E) Missing responses are not coded

Accepted Answer

The number 9 is often used to code missing responses in datasets, especially when dealing with numerical data where 0 might be a valid response and higher numbers like 100 or symbols are not practical.

Question 10

Which term below refers to an analytical process for measuring the semantic content of a communication?
A) ANOVA
B) Regression
C) Content analysis
D) Factor analysis
E) Reliability analysis

Accepted Answer

Content analysis is a research method used to analyze and measure the semantic content in a communication by systematically coding and categorizing the text, images, or other media used in the communication. ANOVA, regression, factor analysis, and reliability analysis are statistical methods used to analyze data and relationships between variables, but are not specific to measuring semantic content.

Question 11

The process of ensuring the accuracy of data and their conversion from raw form into classified forms appropriate for analysis is called _____.
A) coding
B) data entry
C) data preparation
D) data measurement
E) quality control

Accepted Answer

Data preparation involves the process of ensuring accuracy, completeness, and consistency of data, as well as transforming raw data into a format that is suitable for analysis. Options A, B, D, and E are all aspects of the broader data preparation process.

Question 12

Which of the following guidelines must be followed in the development and use of coding rules?
A) Categories within a single variable must be appropriate
B) Categories within a single variable must be exhaustive
C) Categories within a single variable must be mutually exclusive
D) Categories must be derived from one classification principles
E) All of the above

Accepted Answer

All of the given guidelines must be followed in the development and use of coding rules to ensure accuracy and consistency in data coding. Categories within a single variable must be appropriate, exhaustive, and mutually exclusive to avoid overlapping or missing data. Moreover, all categories must be derived from one classification principle to ensure uniformity in data coding.

Question 13

For the vacation survey,how many variables would be represented in the codebook with this question?
A) 1
B) 2
C) 3
D) 4
E) 6

Accepted Answer

The question likely involves multiple parts or options that need to be coded separately in the codebook, such as destination, duration, budget, type of accommodation, activities, and companions, totaling 6 distinct variables.

Question 14

Which of the following code descriptions is most appropriate for coding responses to the vacation survey?
A) 1 = beach, 2 = spa, 3 = adventure, 4 = big city, 5 = foreign travel, 6 = cruise
B) 1 = beach only, 2 = beach and spa, 3 = beach, spa, and adventure, 4 = beach, spa, adventure, and big city, 5 = beach, spa, adventure, big city, and foreign travel, 6 = all of the above
C) 1 = one item checked, 2 = two items checked, 3 = three items checked, 4 = four items checked, 5 = five items checked, 6 = six items checked
D) 1 = yes, 0 = no for each variable
E) None of the above

Accepted Answer

Option D is the most appropriate because it allows for a binary coding system (1 = yes, 0 = no) for each vacation preference, enabling a clear and flexible way to record responses for any combination of vacation types.

Question 15

Closed questions are favored over open-ended questions by researchers for all of the following reasons EXCEPT _____.
A) ease of coding
B) ease of recording
C) ease of analysis
D) insight provided
E) efficiency

Accepted Answer

Closed questions provide limited insight as compared to open-ended questions, which allows for more detailed answers and potentially unexpected responses. Therefore, closed questions are not favored over open-ended questions for insight provided.

Question 16

A codebook generally contains all of the following information except _____.
A) variable number
B) record number
C) code description
D) instructions for coding
E) variable name

Accepted Answer

A codebook typically includes information about variables being studied, such as variable number, variable name, code description, and instructions for coding. However, record number does not typically appear in a codebook. Record number refers to the unique identifier for each individual or case in a dataset and is typically included in the dataset itself, not the codebook.

Question 17

In the example,employment levels and student status are both included as response options.This indicates that the requirement for categories to be _____ may be in violation.
A) appropriate
B) exhaustive
C) mutually exclusive
D) of a single dimension
E) numeric
