Question

use the appropriate formulas and methods to answer the following questions. do not use technology as an aid, unless otherwise stated. below are iq scores from 30 randomly selected adults. { 60, 70, 79, 79, 81, 82, 83, 84, 91, 94, 95, 96, 99, 101, 101, 104, 104, 106, 107, 107, 108, 110, 111, 112, 114, 115, 118, 124, 124, 124 }. first, give the mean of the data set. next, give the median of the data set. now give the mode of the data set. if there is more than one, write them in order, separated by commas. finally, give the midrange of the data set.

Explanation:

Step1: Recall mid - range formula

The mid - range is calculated as $\frac{\text{Minimum value}+\text{Maximum value}}{2}$.

Step2: Identify minimum and maximum values

In the data set $\{60,70,79,79,81,82,83,84,91,94,95,96,99,101,101,104,104,106,107,107,108,110,111,112,114,115,118,124,124,124\}$, the minimum value is $60$ and the maximum value is $124$.

Step3: Calculate mid - range

$\frac{60 + 124}{2}=\frac{184}{2}=92$.

Answer:

$92$
