100% Correct!!
frequency distribution - (ANSWER)A tabular summary of data showing the number (frequency) of
observations in each of several distinctive (nonoverlapping) categories or classes.
relative frequency - (ANSWER)A ratio that compares the frequency of each category to the total.
frequency of the class / n where n = total count of all classes
relative percentage - (ANSWER)percentage of time the value occurs in the sample or population
relative frequency x 100
charting - (ANSWER)a means to represent frequencies visually
column chart - (ANSWER)Data graphed as a series of vertical bars
x-axis: class
y-axis: frequency of class
bar chart - (ANSWER)Data graphed as a series of horizontal bars
x-axis: frequency of class
y-axis: class
pie chart - (ANSWER)a chart that shows the relationship of a part to a whole
best suited for the distributions focused on the proportions
3 step method to group numerical data into classes - (ANSWER)1. determine the number of classes to be
evaluated
2. determine the width of each class

100% Correct!!
3. determine the limits of each class
Number of classes - (ANSWER)(usu b/w 5 and 20)
less than 25 > 5 to 6
25 to 50 > 7 to 14
More than 50 > 15-20
Width of class - (ANSWER)approx width =
(largest data value - smallest data value) / # of classes
qualitative data - (ANSWER)frequency distributions
relative frequency distributions
percent frequency distributions
Graphical: bar, column, pie charts
quantitative data - (ANSWER)frequency distributions
relative frequency distributions
percent frequency distributions
Graphical: histograms
positive relationship - (ANSWER)an association between two variables in which they increase or
decrease together
negative relationship - (ANSWER)an association between two variables in which one increases while the
other decreases
