45) When a researcher wants to show classes or groups of data in proportion to the whole data set, the most appropriate graphical representation would be: Group of answer choices A pie chart. A bar chart. A line graph. Information graphics.

46)

When exploring the relationships between variables, there are certain basic guidelines to follow. This include:

Group of answer choices

The relationship between two nominal/ordinal variables can be assessed with a clustered bar chart or cross-tabulation and a pie chart.

The relationship between a nominal/ordinal variable and a continuous variable can be assessed with a box plot and a dichotomous variable.

The relationship between two continuous variables can be assessed with a scatter plot, and the relationship between a nominal/ordinal variable and continuous variable can be assessed with a box plot.

The relationship between two continuous variables can be assessed with a scatter plot and a pie chart.

47)

In practice, market researchers are usually faced with more than one variable. The relationships between these variables must also be determined. The most appropriate technique would be:

Group of answer choices

Cross-tabulation.

Research designs

Data alteration.

Qualitative research.

48)

To graphically assess the differences between a continuous and a nominal variable, a box plot is used. The horizontal line in the box plot generally indicates:

Group of answer choices

The mode.

The arithmetic mean.

The average

The median

49)

When the probability of making Type 1 errors decreases, the risk increases of not rejecting a null hypothesis while it is actually false. This step in the hypothesis testing relates to which of the following?

Group of answer choices

Specify the level of significance required.

Formulate the null and alternative hypotheses.

Select the appropriate statistical test.

Determine the value of the test statistic.

50)

In hypothesis testing, what is the step where a test can be used to calculate the test size of the gathered data?

Group of answer choices

Formulate the null and alternative hypothesis.

Specify the level of significance required.

Determine the value of the test statistic.

Select the appropriate statistical test.
