Question Help * Explain the difference between a bar graph and a pie chart Choose the correct answer below A. In a bar graph, a slice of a rectangle is shaded for each class of the qualitative variable with its width corresponding to the class frequency or class relative ○ B. In a bar graph, a bar or rectangle is drawn above each class of the qualitative variable corresponding to the class frequency or class relative frequency. In a pie ° C. In a bar graph, each bar or rectangle corresponds to the relative frequency of a class of the qualitative variable. In a pie chart, a slice is drawn above each class of OD. In a bar graph, a bar or rectangle is drawn for each class of the qualitative variable with its width corresponding to the class frequency or class relative frequency. frequency. In a pie chart, each slice of the pie corresponds to the frequency of a class of the qualitative variable chart, each slice of the pie corresponds to the relative frequency of a class of the qualitative variable. the qualitative variable corresponding to the class frequency or class relative frequency. In a pie chart, each class is represented by a pie (or circle) that is proportional to its relative frequency.

Answer 1

A bar graph is a visualization form in which different bars are drawn for different classes. The size of the rectangle corresponds to the class frequency.

A pie chart is a visualization form in which each slice of the pie represents the relative frequency of the class.

Thus, the correct answer is option B.

Fact check: option A and option D both say that the width of the bar graph represents the frequency which is incorrect. Option C says that the bar in a bar graph represents the relative frequency, which is incorrect. Thus, option B is the correct answer.
