Question 1

Which of the following statistical techniques is appropriate for analyzing data if there are several measurements of each element and each variable is analyzed in isolation?
A) univariate techniques
B) multivariate techniques
C) random techniques
D) parallel techniques
E) non-uniform techniques

Accepted Answer

Univariate techniques are appropriate for analyzing data in which each variable is analyzed in isolation, regardless of the number of measurements for each element.

Question 2

According to the text, a survey discloses that 31 percent of the respondents preferred the client's brand, while 30.8 percent preferred the closest competing brand. In such a case, it is perfectly fine to announce that the client's brand is the dominant brand. Such a situation would be ________.
A) acceptable based on the facts of the survey
B) acceptable if only the client was told this
C) impossible to weigh in with a moral judgment based on these details
D) unacceptable if only the client was told this
E) unacceptable because it is misleading. The brands have virtual parity.

Accepted Answer

The difference between 31 percent and 30.8 percent is very small, indicating that the two brands are nearly equal in preference among respondents. Claiming one brand as the dominant based on such a slim margin is misleading, as it suggests a significant lead over the competitor, which is not the case.

Question 4

Which of the following statistical techniques are concerned with the simultaneous relationships among two or more phenomena?
A) univariate techniques
B) multivariate techniques
C) random techniques
D) parallel techniques
E) uniform techniques

Accepted Answer

Multivariate techniques are concerned with the simultaneous relationships among two or more phenomena. Univariate techniques only analyze one variable at a time, whereas random, parallel, and uniform techniques are not statistical techniques commonly used in data analysis.

Question 6

Statistical techniques appropriate for analyzing data when there is a single measurement of each element in the sample are called ________.
A) univariate techniques
B) multivariate techniques
C) random techniques
D) parallel techniques
E) uniform techniques

Accepted Answer

Univariate techniques are specifically designed for analyzing data with only one variable or measurement per observation. These techniques include measures of central tendency, dispersion, and inference based on probability distributions. Multivariate techniques are more appropriate for analyzing data with multiple variables per observation. Random techniques and parallel techniques are not specific types of statistical techniques, and uniform techniques do not relate to the analysis of data.

Question 7

________ are statistical techniques suitable for analyzing data when there are two or more measurements on each element and the variables are analyzed simultaneously.
A) Univariate techniques
B) Multivariate techniques
C) Random techniques
D) Parallel techniques
E) Uniform techniques

Accepted Answer

Multivariate techniques are specifically designed to analyze data with two or more measurements on each element and allow for the simultaneous analysis of multiple variables. Univariate techniques, on the other hand, are suitable for analyzing data with only one measurement per element. Random, parallel, and uniform techniques are not relevant in this context.
