Question 1

Bar graphs:

Accepted Answer

A) Depict frequency distributions, using bars to show the number or percentage of cases for each category of a variable. 
B) Are best used with ratio level variables. 
C) Contain bars that touch each other. 
D) Have varying distances horizontally between each bar. A

Question 2

The vertical line on a graph:

Accepted Answer

A) Is called the x-axis. 
B) Never displays the number or percentages of cases for each value of a variable. 
C) Might display different levels of a second variable, thus showing whether changing levels of categories on the variable on the horizontal axis move in a consistent fashion with changing levels of the second variable. 
D) Is always a variable. C

Question 3

The horizontal line on a graph is called the y-axis, or ordinate.

Accepted Answer

A) True 
 B)False  False

Question 4

Pie charts:

Accepted Answer

A) Portray frequency distribution data in terms of percentages represented by slices of a pie or sections of a circle. 
B) Show bigger slices of pie for categories with the higher percentages of cases. 
C) Work best when the number of categories being portrayed is not extensive. 
D) All of these

Question 5

Histograms:

Accepted Answer

A) Work best with nominal level variables. 
B) Look like bar graphs with bars that touch each other. 
C) Never can be used with values that are collapsed into grouped categories. 
D) Always have bars of equal width.

Question 6

Graphs and charts come in a variety of formats; which format is best to use will depend on the purpose of the graph or chart.

Accepted Answer

A) True 
 B)False

Question 7

Line graphs are useful when our purpose is to show trends over time.

Accepted Answer

A) True 
 B)False

Question 8

The horizontal line on a graph is called the x-axis or abscissa, and typically displays the values of a variable.

Accepted Answer

A) True 
 B)False

Question 9

Histograms can be used to depict frequencies with ordinal, interval or ratio level variables.

Accepted Answer

A) True 
 B)False

Question 10

The x-axis on a graph is:

Accepted Answer

A) The vertical line. 
B) The horizontal line. 
C) The point of origin. 
D) The point of no return.

Question 11

Frequency polygons:

Accepted Answer

A) Use bars, just like bar graphs. 
B) Typically involve interval- or ratio-level variables. 
C) Typically involve nominal-level variables. 
D) Never can be used with values that are collapsed into grouped categories.

Question 12

Line graphs can be misleading by:

Accepted Answer

A) Changing the spacing between categories on the vertical or horizontal axis so as to convey a more dramatic pattern or perhaps a less dramatic pattern. 
B) Spreading out the distance between intervals on the vertical axis, and squeezing the intervals on the horizontal axis closer together. 
C) Squeezing the intervals on the vertical axis closer together while spreading out the intervals on the horizontal axis. 
D) All of these. 
E) None of the these; line graphs are never misleading.

Question 13

Graphs that typically involve interval-or ratio-level variables are:

Accepted Answer

A) Frequency polygons. 
B) Histograms. 
C) Pie charts 
D) Bar graphs.

Question 14

When constructing line graphs, you should:

Accepted Answer

A) Lengthen or shorten the spaces between the categories on the vertical line to convey the pattern that will best support your argument. 
B) Lengthen or shorten the spaces between the categories on the horizontal line to convey the pattern that will best support your argument. 
C) Lengthen or shorten the spaces between the categories on both the vertical line and the horizontal line to convey the pattern that will best support your argument. 
D) Avoid changing the spacing to make it fit your argument.

Question 15

The point at which the horizontal and vertical lines meet on a graph is called the point of origin.

Accepted Answer

A) True 
 B)False
