UCF QMB3200 Midterm Study Questions
and Answers Verified by Experts
Cumulative Relative Frequency Distribution A tabular summary of quantitative data
showing the fraction or proportion of data values that are less than or equal to the upper class
limit of each class.
Cumulative Percent Frequency Distribution A tabular summary of quantitative data
showing the percentage of data values that are less than or equal to the upper class limit of each
class.
Stem-and-leaf Display a graphical display used to show simultaneously the rank order and
shape of a distribution of data
Crosstabulation A tabular summary of data for two variables. The classes for one variable
are represented by the rows; the classes for the other variable are represented by the columns.
Simpson's Paradox Conclusions drawn from two or more separate crosstabulations that
can be reversed when the data are aggregated into a single crosstabulation.
,Scatter Diagram A graphical display of the relationship between two quantitative
variables. One variable is shown on the horizontal axis and the other variable is shown on the
vertical axis.
Trendline a line that provides an approximation of the relationship between two variables
Side-by-side Bar Chart a graphical display for depicting multiple bar charts on the same
display
Stacked Bar Chart A bar chart in which each bar is broken into rectangular segments of a
different color showing the relative frequency of each class in a manner similar to a pie chart.
Mean a measure of central location computed by summing the data values and dividing by
the number of observations.
Excel: Mean =AVERAGE()
Median A measure of central location provided by the value in the middle when the data
are arranged in ascending order.
, Excel: median =MEDIAN()
Mode A measure of location, defined as the value that occurs with greatest frequency.
Excel: mode =MODE.SNGL()
Weighted Mean the mean obtained by assigning each observation a weight that reflects its
importance
Geometric Mean A measure of location that is calculated by finding the nth root of the
product of n values.
Excel: geometric mean =GEOMEAN()
Percentile A value that provides information about how the data are spread over the
interval from the smallest to the largest value.
