Chapter 3, Problem 1CRP
a.
To determine
Identify the measures of variation that indicate spread about the
a.
Expert Solution
Answer to Problem 1CRP
The measures of variation that indicate spread about the mean is standard deviation and variance.
Explanation of Solution
The measures of variation describe the spread of the data. The standard deviation and variance is used to describe the spread of the data around the mean. The standard deviation is based on the difference between each data value and the mean of the data. Moreover, the average spread of the data around the mean is provided by the standard deviation. Hence, the measures of variation indicated spread about the mean is standard deviation and variance.

To determine
Identify the graphic display that shows the
b.
Expert Solution
Answer to Problem 1CRP
The graphic display that shows the median and data spread about the median is box-and-whisker plot.
Explanation of Solution
The spread of the data around the median is identified using box-and-whisker plot. Moreover, the box-and-whisker is created using the

What will the resulting clusters be when using the k-Means method with k = 2. In your own words, explain why this result is
indeed expected, i.e. why this clustering minimises the ESS map.

PS
9 Two films are shown on screen A and screen B at a cinema each evening. The numbers
of people viewing the films on 12 consecutive evenings are shown in the back-to-back
stem-and-leaf diagram.

74 1645678
92 71689
Key: 116|4 represents 61 viewers for A and 64 viewers for B
A second stem-and-leaf diagram (with rows of the same width as the previous diagram)
is drawn showing the total number of people viewing films at the cinema on each of
these 12 evenings. Find the least and greatest possible number of rows that this second
diagram could have.
TIP
On the evening when 30 people viewed films on screen A, there could have been as few
as 37 or as many as 79 people viewing films on screen B.
