Chapter 5, Problem 10E

a)

To determine

To explain the shape of the distribution.

Answer to Problem 10E

Symmetric.

Explanation of Solution

Given:

  

Calculation:

The shape of the distribution is symmetric.

b)

To determine

To find rang of the strength scores.

Answer to Problem 10E

The range is 4.

Explanation of Solution

Given:

  

Calculation:

We know, range is the difference between highest and lowest values.

  $Range=5-1=4$

c)

To determine

To explain the hidden facts.

Answer to Problem 10E

We don’t know the number of results produced by each procedure done.

Explanation of Solution

Given:

  

Calculation:

From histogram, we don’t know the number of results produced by each procedure done. Therefore, it shows fairly low variations from the mean. This fact is hidden in Histogram.

d)

To determine

To explain which method had higher median score.

Answer to Problem 10E

Biceps.

Explanation of Solution

Given:

  

Using boxplot, the higher median shows for the biceps transfer method as compare to Deltoid transfer method.

e)

To determine

To explain whether Biceps transfer method is always best.

Answer to Problem 10E

No.

Explanation of Solution

Given:

  

The lower IQR and highest outliers of Deltoid can be best for sometimes. Hence, Deltoid is not always best method.

f)

To determine

To explain which method produces most consistent results.

Answer to Problem 10E

Deltoid.

Explanation of Solution

Given:

  

The lower IQRof Deltoid deal as consistent results as compare to Biceps.
