Question 1

Which of the following is not a measure of dispersion?

Accepted Answer

Mean is a measure of central tendency, not a measure of dispersion. The other options are all measures of dispersion.

Question 2

Checking to determine whether the proper screener questions were invoked would be part of which step in the data analysis procedure?

Accepted Answer

Validation involves checking all aspects of the data cleaning process, including ensuring that proper screener questions were asked and filtered appropriately. This step is critical for ensuring the accuracy and validity of the data. The other options (coding, machine cleaning, data entry, and checks and balances) do not specifically address the role of screener questions in data analysis.

Question 3

Finding the value that occurs most frequently determines the__________.

Accepted Answer

The mode is the value that occurs most frequently in a set of data, so finding the mode determines the most common value. The standard deviation measures the spread or variability of the data, the variance is the squared standard deviation, the mean is the average of the data, and the median is the middle value when the data is arranged in order. Therefore, the correct answer is B) mode.

Question 4

Which of the following is not a measure of dispersion?

Accepted Answer

Median is a measure of central tendency, not a measure of dispersion.

Question 5

The last step in the data analysis procedure is:

Accepted Answer

The answer of The last step in the data analysis...

Question 6

The process of ascertaining that interviews were actually conducted is known as:

Accepted Answer

Validation is the process of confirming that interviews were actually conducted. It involves establishing the truth or validity of the data collected during interviews. This is typically done by cross-checking the interviews with other sources of information or by using statistical techniques to assess the reliability of the data. The other options (coding, machine cleaning, data entry, and checks and balances) are all related to different aspects of data management but do not specifically address the issue of interview validation.

Question 7

Validation of data is an attempt to check the accuracy of the work done by _______

Accepted Answer

The answer of Validation of data is an attempt to...

Question 8

Which of the following is the most flexible type of graph?

Accepted Answer

The answer of Which of the following is the most...

Question 9

Which type of data entry ensures that data is entered properly?

Accepted Answer

Intelligent data entry uses algorithms and validation checks to ensure accuracy in data entry, reducing the risk of errors. Scanning and coding can also aid in data entry, but may not guarantee thorough accuracy. Marginal data entry is not a recognized method.

Question 10

If we conclude that the average weekly amount of soft drink consumption by males and females is about the same,but that the standard deviation among males is greater than that for females,what would this mean?

Accepted Answer

This means that while on average males and females drink the same amount of soft drinks, there is more variation in the amount of soft drinks consumed by males. It does not necessarily mean that males drink more than females, just that there is more diversity in their consumption patterns.

Question 11

Which of the following does validation typically address?

Accepted Answer

The answer of Which of the following does validation typically...

Question 12

Which type of analysis cannot be computed with nominal data?

Accepted Answer

Nominal data does not have a mathematical value, so it does not make sense to calculate the mean.

All the other options (B, C, and D) are possible to compute with nominal data. The mode is the value that appears most frequently in the data, frequency is the number of occurrences of each value, and percentage represents each value's proportion in the sample.

Question 13

This analytical procedure shows the responses to one question relative to the responses of another question.

Accepted Answer

Cross tabulation is the analytical procedure that shows the responses to one question relative to the responses of another question by constructing a table with the row and column variables representing each survey question. It allows for the comparison of the distribution of responses between two variables, providing insights into the relationship between them. One-way frequencies, t-tests, and z-tests do not allow for such a comparison.

Question 14

The quality control aspect of the data analysis procedure refers to:

Accepted Answer

Quality control in data analysis refers to the validation and editing of data to ensure accuracy and completeness. Validating the data involves checking it for errors, such as missing data, outliers, or inconsistencies in responses. Editing refers to the process of correcting these errors. Both steps are critical in ensuring that the data used for analysis is reliable and accurate. Statistical analysis, properly training interviewers, and coding of questionnaires are all important aspects of the research process, but they do not fall under the quality control aspect of data analysis.

Question 15

With one-way frequency tables,the base size for a question would not take into consideration:

Accepted Answer

One-way frequency tables only present information on one variable or question, so they do not consider population size or total respondents. They only show the number of people who answered a particular question, but not the number of people asked that question. Therefore, the base size for a question with a one-way frequency table would not take into consideration population size.

Question 16

This type of chart is the simplest form of chart and is useful for presenting a measurement taken at several points over time.

Accepted Answer

A line chart is specifically designed to present a measurement taken at several points over time. It is easier to see the trend and changes over time with a line chart as compared to a bar chart or pie chart. Therefore, a line chart is the best choice for presenting such data.

Question 17

Out of the following,which would typically have the largest base size?

Accepted Answer

Base size refers to the total number of individuals in the population or sample from which data is being collected. Since total respondents are the individuals who actually responded to the survey or research, they would typically have the largest base size compared to the other options given.

Question 18

This measure of central tendency can be computed only from interval or ratio data.

Accepted Answer

The mean can only be computed from interval or ratio data because it requires the use of numerical values and computations that involve addition and division. The mode and median, on the other hand, can also be computed from ordinal data. Therefore, the correct answer is C.

Question 19

The process of converting information into a form that can be read by a computer is known as _______.

Accepted Answer

Data entry is the process of converting information into a form that can be read by a computer.

Question 20

If an interviewer did not properly follow skip patterns specified in a questionnaire,the ______________ step in data analysis would reveal the problem.

Accepted Answer

Validation is the step in data analysis where the data is checked for accuracy and completeness, ensuring that the skip patterns were followed correctly.
