Question 1

An ogive is a graph that shows cumulative relative frequency.

Accepted Answer

A) True 
 B)False  True

Question 2

When the Histogram tool in Excel is used to construct a frequency distribution and histogram,the default histogram is in the proper format and will require only that you add appropriate labels.

Accepted Answer

A) True 
 B)False  False

Question 3

Why should a histogram contain no gaps between the bars but a bar chart may have gaps?

Accepted Answer

A histogram is used to convey the distribution of a quantitative variable.The horizontal axis represents the range of possible values for the variable of interest.The bars are joined together to form the distribution.A bar chart is used to illustrate a qualitative variable.By using gaps between the bars,the differences between the categories are more easily seen.

Question 4

At a manufacturing plant workers are divided into 4 different teams that rotate shifts.The number of units produced by each team is recorded.The best type of chart to display the data is a:

Accepted Answer

A) pie chart. 
B) histogram. 
C) ogive. 
D) line chart. 
A) pie chart. 
B) histogram. 
C) ogive. 
D) line chart.

Accepted Answer

A) Nominal level data 
B) Quantitative data 
C) Time-series data 
D) Ordinal data 
A) Nominal level data 
B) Quantitative data 
C) Time-series data 
D) Ordinal data

Question 6

A stem and leaf diagram is an alternative to using:

Accepted Answer

A) a pie chart. 
B) a bar chart. 
C) a histogram. 
D) an ogive. 
A) a pie chart. 
B) a bar chart. 
C) a histogram. 
D) an ogive.

Question 7

It is often a good idea to convert frequency distributions to relative frequency distributions when you wish to compare two distributions with different amounts of data.

Accepted Answer

A) True 
 B)False

Question 8

Recently a study of fans attending the New York Mets baseball games was conducted and 500 fans were surveyed.In forming a frequency distribution of the number of miles fans traveled from home to the stadium,it was found that 247 fans traveled between 0 and 5 miles.Based on this information what was the relative frequency for this class?

Accepted Answer

A) 0.247 
B) 0.30 
C) 0.494 
D) Can't be determined without more information. 
A) 0.247 
B) 0.30 
C) 0.494 
D) Can't be determined without more information.

Accepted Answer

A frequency histogram can be used to con

Question 10

A stem and leaf diagram is most similar to a bar chart.

Accepted Answer

A) True 
 B)False

Question 11

The Wilson company monitors customer complaints and organizes these complaints into six distinct categories.Over the past year,the company has received 534 complaints.One possible graphical method for representing these data would be a histogram.

Accepted Answer

A) True 
 B)False

Question 12

Recently a survey was conducted in which customers of a large insurance company were asked to indicate the number of speeding tickets they had received in the past three years.The data in this case would most likely be analyzed using a frequency distribution with the data grouped into classes such as 0-2,3-5,6-8,etc.

Accepted Answer

A) True 
 B)False

Question 13

A bar chart is the same as a histogram.

Accepted Answer

A) True 
 B)False

Question 16

If you have constructed a joint frequency distribution manually and now wish to convert it to a joint relative distribution,the proper method is to divide each cell frequency by the cell's row total.

Accepted Answer

A) True 
 B)False

A) Quantitative data 
B) Categorical data 
C) Nominal level data 
D) Ordinal data

Question 19
