Histograms and frequency distributions summarize data. The data in
the question are the individual observations that are not summarized.

When data is collected using a quantitative, ratio variable, what is
true about a frequency distribution that summarizes the data?
A.
Upper and lower class limits must be
calculated.
B.
A pie chart can be used to summarize
the data.
C.
Number of classes is equal to the number of variable's
values.
D.
The "5 to the k rule" can be
applied.
Choices B and C refer to frequency distributions for qualitative
variables. For quantitative, ratio variables, the number of classes, the
class interval, and class limits must be computed.

When data is collected using a qualitative, nominal variable, what is
true about a frequency distribution that summarizes the data?
A.
The upper and lower class limits must be
calculated.
B.
A pie chart can be used to summarize
the data.
C.
The number of classes is equal to the number of variable's
values plus 2.
D.
The "5 to the k rule" can be
applied.
A pie chart is used to show the relative frequency for a qualitative,
nominal variable. Choices A and D apply to quantitative variables.

When data is collected using a qualitative, nominal variable (in other
words, male or female), what is true about a frequency distribution
that summarizes the data?
A.
The upper and lower class limits must be
calculated.
B.
Class midpoints can be
computed.
C.
The number of classes corresponds to the number of a
variable's values.
D.
The "2 to the k rule" can be
applied.
Gender is a nominal, qualitative variable that has two values.
Therefore, the frequency distribution will only have two classes: male
and female.

A student was interested in the cigarette smoking habits of college
students and collected data from an unbiased random sample of
students. The data is summarized in the following table:
Why is the table NOT a frequency distribution?
