For Further Thought (cont.)
In an actual experiment, we could obtain observed
frequencies (or empirical frequencies), which
would most likely differ somewhat from the expected
frequencies. But 64 repetitions of the experiment
should be enough to provide fair consistency between

the mode may not exist. On the other hand, for
nonnumeric data, it may be that
none of the three measures exists, or that only the mode exists.
2. Because even a single change in the data may cause the mean to change, while
the median and mode may not be affected at all, the mean is the most “sensi
3. In a symmetric distribution, the mean, median, and mode (if a single mode
exists) will all be equal. In a nonsymmetric distribution, the mean is often
unduly affected by relatively few extreme values and, therefore, may not be a
good representative measure of central tendency. For example, distributions of
salaries, family incomes, or home prices often include a few values that are
much higher than the bulk of the items. In such cases, the median is a more use
ful measure.
4. The mode is the only measure covered here that must always be equal to one of
the data items of the distribution. In fact, more of the data items are equal to
the mode than to any other number. A fashion shop planning to stock only
one hat size for next season would want to know the mode (the most com
mon) of all hat sizes among their potential customers. Likewise, a designer of
family automobiles would be interested in the most common family size. In
examples like these, designing for the mean or the median might not be right
for anyone.
For Further Thought
For Group or Individual Investigation
Simpson’s Paradox
In baseball statistics, a player’s “batting average” gives the
average number of hits per time at bat. For example, a
player who has gotten 84 hits in 250 times at bat has a
batting average of 250 = .336. This “average” can be
interpreted as the empirical probability of that player’s
getting a hit the next time at bat.
The following are actual comparisons of hits and
atbats for two major league players in the 1995, 1996,
and 1997 seasons. The numbers illustrate a puzzling
statistical occurrence known as Simpson’s paradox.
The example below, involving Dave Justice and Derek
Jeter, was referred to in the “Conspiracy Theory”
episode of the television series NUMB3RS. (Source:
www.wikipedia.org)
1. Fill in the twelve blanks in the table, giving batting
averages to three decimal places.
2. Which player had a better average in 1995?
3. Which player had a better average in 1996?
4. Which player had a better average in 1997?
5. Which player had a better average in 1995, 1996,
and 1997 combined?
6. Did the results above surprise you? How can it be
that one player’s batting average leads another’s for
each of three years, and yet trails the other’s for the
combined years?

a given item, x, occurred f times, then the relative frequency of
x is . Example 1 illustrates these ideas.
EXAMPLE 1 Constructing Frequency and Relative Frequency Distributions
The 25 members of a psychology class were polled as to the number of siblings in
their individual families. Construct a frequency distribution and a relative frequency
distribution for their responses, which are shown here.
2, 3, 1, 3, 3, 5, 2, 3, 3, 1, 1, 4, 2, 4, 2, 5, 4, 3, 6, 5, 1, 6, 2, 2, 2
SOLUTION
The data range from a low of 1 to a high of 6. The frequencies (obtained by inspec
tion) and relative frequencies are shown in Table 2.

The numerical data of Table 2 can more easily be interpreted with the aid of a
histogram. A series of rectangles, whose lengths represent the frequencies, are
placed next to one another as shown in Figure 1. On each axis, horizontal and ver
tical, a label and the numerical scale should be shown.
The information shown in the histogram in Figure 1 can also be conveyed by a
frequency polygon, as in Figure 2. Simply plot a single point at the appropriate height
or each frequency, connect the points with a series of connected line segments, and
mplete the polygon with segments that trail down to the axis beyond 1 and 6.
