Deck 5: Graphs and Charts

Question 1

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

Answer 1

True

Question 2

The x-axis on a graph is:

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

Answer 2

The horizontal line.

Question 3

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

Answer 3

True

Question 4

When constructing line graphs, you should:

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 5

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

Question 6

The vertical line on a graph:

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.

Question 7

Pie charts:

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 8

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

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

Question 9

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

Question 10

Bar graphs:

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.

Question 11

Histograms:

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 12

Frequency polygons:

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 13

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.

Question 14

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

Question 15

Line graphs can be misleading by:

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.
