A)Amplification
B)Expansion
C)Augmentation
D)Elaboration

Accepted Answer

Elaboration refers to the process of introducing or controlling for third variables (control or test factors) by subclassifying original tables, which helps in understanding the relationship between the primary variables under study.

Question 5

Which of the following refers to a guidebook for numerically classifying each question to be coded?
A)Reference book
B)Legend
C)Codebook
D)Guidebook

Accepted Answer

A codebook is a document used for gathering and analyzing statistical data, specifically designed to help researchers understand and apply the specific codes to the data they are analyzing. It serves as a guidebook for numerically classifying each question to be coded, ensuring consistency and accuracy in data analysis.

Question 6

Which of the following are a highly inaccurate means of depicting crime change that fails to control for population growth?
A)Crime graphs
B)Crime charts
C)Crime maps
D)Crime clocks

Accepted Answer

Crime clocks are highly inaccurate for depicting changes in crime rates because they do not control for population growth. They simply represent crime occurrences in a given time frame without adjusting for the size of the population, which can lead to misleading interpretations of crime trends.

Question 7

Which of the following,when keyed to questionnaire items,enables the identification and examination of questionnaire content to ensure proper coverage,balance,and non-duplication of items?
A)Q-list
B)Variables list
C)Examination list
D)Questionnaire key

Accepted Answer

The answer of Which of the following,when keyed to questionnaire...

Question 8

Which of the following is NOT one of the steps in the data management process?
A)Collecting the information with the data-gathering instrument
B)Using a codebook
C)Transferring this information onto a codesheet
D)Excluding all data which do not conform with stated hypothesis

Accepted Answer

Excluding all data which do not conform with the stated hypothesis is not a step in the data management process. This would introduce bias and potentially invalidate the research. Data management typically involves collection, coding, and transferring data for analysis, but it should not involve discarding data based on conformity to hypotheses.

Question 9

Which of the following are presentations of quantitative data in a summary or uniform fashion?
A)Charts
B)Graphs
C)Clocks
D)Tables

Accepted Answer

The answer of Which of the following are presentations of...

Question 10

Which of the following are meaningful ways of standardizing data so that useful comparisons can be made between unequal populations?
A)Rates
B)Proportions
C)Percentages
D)All of the above

Accepted Answer

Rates, proportions, and percentages are all methods used to standardize data, allowing for meaningful comparisons across different populations by adjusting for size differences.

Question 11

Which of the following must be completed prior to the actual coding?
A)Cleaning
B)Manipulation
C)Editing
D)Expurgation

Accepted Answer

Editing is a crucial step that must be completed before the actual coding process in various contexts, such as data preparation or software development. It involves reviewing and correcting errors or inconsistencies to ensure the data or code is accurate and ready for the next steps.

Question 12

Which of the following involves double checking the data file in search of errors,many of which are inevitable despite the conscientiousness of workers?
A)Data verification
B)File accuracy search
C)Entry accuracy verification
D)None of the above

Accepted Answer

Data verification involves the process of double-checking data for errors to ensure its accuracy and integrity. This is essential in maintaining the quality of data despite the potential for human error during data entry or processing.

Question 13

Which of the following should be planned at the beginning of a project rather than at the end?
A)Finding sources
B)Data analysis
C)Research assistants
D)None of the above

Accepted Answer

The answer of Which of the following should be planned...

Question 14

Which of the following refers to graphical circles whose pieces represent proportions of some phenomenon and total 100 percent?
A)Pie charts
B)Bar graphs
C)Frequency polygons
D)All of the above

Accepted Answer

Pie charts are graphical representations where circles are divided into sectors or "slices" to illustrate numerical proportions; the sum of the slices represents 100% of the whole.

Question 15

Which of the following depicts the frequency or percentages of the midpoint of each score value are plotted and connected by a straight line that begins and ends at the baseline.
A)Pie charts
B)Bar graphs
C)Frequency polygons
D)All of the above

Accepted Answer

Frequency polygons are graphical representations where the frequencies or percentages of the midpoint of each score value are plotted and connected by straight lines. This starts and ends at the baseline, distinguishing them from pie charts and bar graphs.

Question 16

Which of the following is the assignment of numerical values to responses information)gathered by a research instrument?
A)Coding
B)Editing
C)Syncing
D)Merging

Accepted Answer

Coding is the process of assigning numerical values to responses collected through a research instrument, facilitating data analysis.

Question 17

Which of the following is the most widely used means of inputting data?
A)Voice-to-text
B)Hand-to-hand
C)Voice data entry

Which of the following tables consists of a two-variable cross tabulation and examines how one variable influences the other?
A)Bilateral table
B)Bivariate table
C)Parallel table
D)None of the above

Accepted Answer

A bivariate table, also known as a cross-tabulation or contingency table, is designed to analyze the relationship between two variables by displaying the distribution of one variable across the levels of the other variable, thus examining how one variable may influence the other.
