Question 1

A graphical device for presenting categorical data summaries based on subdivision of a circle into sectors that correspond to the relative frequency for each class is a _____.
A) histogram
B) stem-and-leaf display
C) pie chart
D) bar chart

Accepted Answer

A pie chart is specifically designed for showing relative frequencies of different categories in a circular format. It can be useful for visualizing percentages or proportions, but cannot effectively display raw values or trends over time. Histograms and bar charts are better for displaying numerical data, while stem-and-leaf displays are used for showing actual values in a compact format.

Question 2

A common graphical presentation of quantitative data is a _____.
A) histogram
B) bar chart
C) relative frequency
D) pie chart

Accepted Answer

A histogram is the most suitable graphical presentation of quantitative data as it shows the distribution of continuous numerical data into intervals or "bins". It displays the frequencies or count of data points in each bin on the y-axis and the bins on the x-axis. A bar chart is more appropriate for categorical data, relative frequency is a numerical representation of data, and a pie chart is best used for displaying percentages or proportions.

Question 3

A graphical presentation of a frequency distribution, relative frequency distribution, or percent frequency distribution of quantitative data constructed by placing the class intervals on the horizontal axis and the frequencies on the vertical axis is a _____.
A) histogram
B) bar chart
C) stem-and-leaf display
D) pie chart

Accepted Answer

A histogram is the most appropriate choice for displaying frequency distributions of quantitative data. It allows for the visualization of the shape of the distribution and the identification of the central tendency and variability of the data. Bar charts are typically used for displaying categorical data, stem-and-leaf displays are useful for showing the actual data values within each class interval, and pie charts are more appropriate for displaying relative proportions of different categories within a whole.

Question 4

To construct a bar chart using Excel's Chart Tools, choose __________ as the chart type.
A) column
B) pie
C) scatter
D) line

Accepted Answer

A column chart is used for displaying data in vertical columns, which makes it the best choice for constructing a bar chart in Excel. Each column represents a category, and the height of the column corresponds to the value of that category.

Question 5

The difference between the lower class limits of adjacent classes provides the _____.
A) number of classes
B) class limits
C) class midpoint
D) class width

Accepted Answer

The difference between the lower class limits of adjacent classes provides the class width, which is the range of values that are included in each class.

Question 6

Excel's __________ can be used to construct a frequency distribution for quantitative data.
A) COUNTIF function
B) SUM function
C) PivotTable report
D) AVERAGE function

Accepted Answer

PivotTable reports in Excel can be used to construct frequency distributions for quantitative data by summarizing and grouping the data into intervals or bins. The resulting table displays the count, sum, average, or other function of the data within each interval or bin. The COUNTIF function can also be used to count the number of occurrences of a specific value or range of values in a data set, but it does not group the data into intervals or bins. The SUM and AVERAGE functions are used to calculate the total or average of a range of values, but they do not create frequency distributions.

Question 7

To construct a pie chart using Excel's Chart Tools, choose __________ as the chart type.
A) column
B) pie
C) scatter
D) line

Accepted Answer

The pie chart type is specifically designed to display data as a pie, making it the best choice for constructing a chart that accurately shows how much each data point contributes to the whole.

Question 8

A __________ can be used to graphically present quantitative data.
A) histogram
B) pie chart
C) stem-and-leaf display
D) histogram and a stem-and-leaf display

Accepted Answer

Both a histogram and a stem-and-leaf display can be used to graphically present quantitative data, allowing for the visualization of data distributions.

Question 9

A graphical device for depicting categorical data that have been summarized in a frequency distribution, relative frequency distribution, or percent frequency distribution is a(n) _____.
A) histogram
B) stem-and-leaf display
C) ogive
D) bar chart

Accepted Answer

A bar chart is the best choice for depicting categorical data summarized in a frequency distribution because it displays the frequencies of each category as bars of equal width and height, making it easy to compare the categories. Histograms are used for continuous data, stem-and-leaf displays are used for small data sets, and ogives are used for cumulative frequency distributions.

Question 10

College students were surveyed to determine how much they planned to spend in various categories during the upcoming academic year. One category is the amount spent on school supplies. The graphs below show the amount of money spent on school supplies by women and men.  Approximately what percent of women spend more than $105 on school supplies?
A) 5%
B) 10%
C) 15%
D) 20%

Accepted Answer

The answer of College students were surveyed to determine how...

Question 11

Categorical data can be graphically represented by using a(n) _____.
A) histogram
B) frequency polygon
C) ogive
D) bar chart

Accepted Answer

A bar chart is the best choice for graphically representing categorical data as it displays the frequency or proportion of each category in a clear and easy to read format. Histograms and frequency polygons are better suited for continuous data and ogives are more useful for cumulative frequency distributions.

Question 12

Frequency distributions can be made for _____.
A) categorical data only
B) quantitative data only
C) neither categorical nor quantitative data
D) both categorical and quantitative data

Accepted Answer

Frequency distributions can be made for both categorical and quantitative data. For categorical data, the frequency distribution shows the count or percentage of observations in each category. For quantitative data, the frequency distribution shows how often each range or bin of values occurs.

Question 13

Excel's Chart Tools can be used to construct a _____.
A) bar chart
B) pie chart
C) histogram
D) All of these can be constructed using Excel's Chart Tools.

Accepted Answer

Excel's Chart Tools include many different chart types that users can construct, including bar charts, pie charts, histograms, and many more. Therefore, all of the above options are correct.

Question 14

When using Excel to create a __________, one must edit the chart to remove the gaps between rectangles.
A) scatter diagram
B) bar chart
C) histogram
D) pie chart

Accepted Answer

A histogram is a type of chart that shows the distribution of a dataset and typically does not have gaps between the rectangles (bars) representing the bins. In Excel, when creating a histogram, you might need to adjust the settings to ensure there are no gaps between the bars, as gaps are not standard for histograms and can misrepresent the data distribution.

Question 15

A(n) __________ is a graph of a cumulative distribution.
A) histogram
B) pie chart
C) stem-and-leaf display
D) ogive

Accepted Answer

An ogive is a graph of a cumulative distribution, showing the cumulative frequency or cumulative relative frequency on the y-axis and the corresponding data values on the x-axis.

Question 16

In a cumulative frequency distribution, the last class will always have a cumulative frequency equal to _____.
A) 1
B) 100%
C) the total number of elements in the data set
D) None of the answers is correct.

Accepted Answer

The cumulative frequency of the last class will always include all the elements in the data set, so it will be equal to the total number of elements in the data set.

Question 17

What is the difference between a bar graph and a histogram?
A) There is no difference between a bar graph and a histogram.
B) A histogram displays quantitative data, while a bar graph displays categorical data.
C) A histogram must have space between the bars, while a bar graph has no spaces between the bars.
D) None of the answers is correct.

Accepted Answer

A histogram is used to display numerical data that has been divided into intervals or bins, while a bar graph is used to display categorical or qualitative data. In a bar graph, the bars represent different categories or groups, whereas in a histogram, the bars represent ranges of values. Additionally, histograms typically have no space between the bars, while there may be space between the bars on a bar graph.
