QNT 2020 MIDTERM QUESTIONS WITH VERIFIED
ANSWERS
When constructing bins for a frequency distribution of quantitative data, which of the
following principles should generally be followed? - Answers - Bins should be mutually
exclusive.
The bins should be exhaustive.
Bins should be the same width.
When constructing a histogram what values/labels go on the horizontal (x) axis and the
vertical (y) axis. - Answers - Quantitative bin limits on the horizontal axis; frequency or
relative frequency on the vertical axis.
Histograms can be used to - Answers - observe the spread or the variability of the data.
determine the shape of the data.
True or false: Distributions of business data are typically (but not always) left skewed -
Answers - False
When determining the approximate width of the bins for a frequency distribution of
quantitative data, the difference of what two values is divided by the number of bins?
Multiple choice question. - Answers - The maximum value and minimum value.
How does one customize an Excel graph? - Answers - Click on the created graph and
use Chart Elements menu to customize.
After creating the basic chart, choose to customize from the Format and Design ribbon
at the top.
One of the primary goals of constructing a frequency distribution for quantitative data is
to summarize the data - Answers - by showing frequency of values that lie within a class
or bin.
The rectangles of a histogram - Answers - represent the class width and frequency, or
relative frequency, of the respective class
represent grouped data
are drawn with no space, or gaps, between them.
Identify ways you can customize a graph on Excel. - Answers - Format axis scales to be
more readable.
Add data values to the graph.
Add a data table underneath the graph.
