Chapter SH, Problem 10.2EP

a.

To determine

To find: The best measure of central tendency that describes the given condition.

Answer to Problem 10.2EP

The best measure of central tendency that describes the given condition here is mean.

Explanation of Solution

Given information: The given condition is:

Jamal scores mostly on his math tests.

As Jamal scores mostly on his math tests so first, it is need to measure average (mean) score by Jamal on his all subjects, then after comparison between the averages scores of all subjects by Jamal we can concluded that Jamal scored averagely higher in mathematics.

Therefore, the best measure of central tendency that describes the given condition here is mean.

b.

To determine

To find: The best measure of central tendency that describes the given condition.

Answer to Problem 10.2EP

The best measure of central tendency that describes the given condition here is mode.

Explanation of Solution

Given information: The statement is:

The teacher ranging the students answer for number of minute students study per day from $15$ minutes to $200$ minutes, and the most common answer being $100$ minutes.

As the mode is the value or values that appear most often in a set of data.

And by the statement that the most common answer being $100$ minutes clears that best measure of central tendency that describes the given condition here is mode.
