Question 6

$$\text { A Pareto chart does $\underline { not }$ have which of the following properties? }$$

A) frequencies arranged from highest to lowest
B) frequencies displayed by the heights of vertical bars
C) classes of data are categorical
D) quantitative variable on the horizontal axis

Accepted Answer

A Pareto chart is characterized by frequencies arranged from highest to lowest (A), frequencies displayed by the heights of vertical bars (B), and classes of data being categorical (C). The horizontal axis of a Pareto chart represents categories, not a quantitative variable, making D the correct choice as it does not describe a property of a Pareto chart.

Question 8

An automobile dealer wants to construct a pie graph to represent types of cars sold in July. He sold 72 cars, 16 of which were convertibles. How many degrees should be
Used for the convertibles section ? 
A) $80 ^ { \circ }$
B) $100 ^ { \circ }$
C) $60 ^ { \circ }$
D) $50 ^ { \circ }$

Accepted Answer

The degree measure for the convertibles section is found by calculating the proportion of convertibles sold relative to the total number of cars, then multiplying by 360 degrees (the total degrees in a circle). So, $ \frac{16}{72} \times 360 = 80 ^ { \circ }$.

Question 10

A Pareto chart is useful for showing percentages of the total at different times.

Accepted Answer

A Pareto chart is primarily used to identify and prioritize problems or defects by showing their frequency or impact in descending order, not for showing percentages of the total at different times.

Question 11

A weatherman records the amount of rain that fell in Portland, Oregon each day for a year. What type of graph should he use to show how rainfall changes during the year?
A) time series graph
B) pictograph

D) pie graph

Accepted Answer

A time series graph is appropriate for displaying data points at successive time intervals, making it ideal for showing how rainfall changes over the course of a year.

Question 12

Question 13

$$\text { A pie graph is $\underline { not }$  useful in showing which of the following characteristics of a data set? }$$

A) categories that make up the largest proportions of the total
B) frequency changes over time
C) relative frequencies for each category in the distribution
D) categories that make up the smallest proportions of the total

Accepted Answer

Pie charts are effective for displaying the proportions of categories at a single point in time, but they do not show changes over time. For tracking changes over time, line graphs or bar charts are more appropriate.
