Chapter 1.3, Problem 104E

(a).

To determine

To Find: Given formula whether used to measure center or spread.

Answer to Problem 104E

  $\frac{Q_1+Q_3}{2}$ used to measure spread of data.

Explanation of Solution

Given:

Formula:

  $\frac{Q_1+Q_3}{2}$

Given quartiles describe about spread of a data by breaking down the data set into quarters, just like the median breaks it in half order.

So, $\frac{Q_1+Q_3}{2}$ is used to measure spread of data.

Conclusion:

Thus, $\frac{Q_1+Q_3}{2}$ used to measure spread of data.

(b).

To determine

To Find: Given formula is used to measure resistant or not.

Answer to Problem 104E

  $\frac{Max-Min}{2}$ is used to measure resistant.

Explanation of Solution

Given:

Formula,

  $\frac{Max-Min}{2}$

Given quartiles describe about spread of a data by breaking down the data set into quarters, just like the median breaks it in half order.

Thus, given formula used for resistant.

Conclusion:

Thus, $\frac{Max-Min}{2}$ is used to measure resistant.
