Question 4

In a gender study related to income, the null hypothesis is:

Question 6

Which of the following tells a marketing researcher the most about the level of agreement among the respondents in the sample when they answered a specific question?

Answer 6

standard deviation

Question 7

After inputing the data for 99 respondents on a Likert scale item (with response options going from 1 to 7), a researcher calculates one of the measures of central tendency. This measure is found to be 5. The researcher then inputs the value for the 100th respondent, which is 6. The measure of central tendency (calculated for all 100 respondents) stays the same. The measure is most probably a (pick the most appropriate response):

Answer 7

Mode or median

In the formula for calculating the standard deviation, the value of the denominator inside the square roots is:

Answer 8

(n-1)

Variance is:

Answer 9

the average squared deviations about the mean of a distribution of values.

Answer 10

Chi-square test
Paired sample t-test
ANOVA

All of the above *

When male students are compared to female students on the average number of hours they study each weekday, this is an example of:

Answer 11

Independent samples

Question 12

The difference between a particular response and the distribution mean is called a(n):

Answer 12

deviation.

Question 13

Perceptual mapping is a process that is used to:

In one-way ANOVA, which of the following requirements must be met?

Answer 16

The dependent variable must be metric while the independent variable must be categorical

Question 17

In a one-way ANOVA, the term “one-way” is used because:

Answer 17

only one independent variable is used in the analysis.

Question 18

T-tests are:

Answer 18
