Given : Doctor A’s data set on glasses
1 answer:
The mean absolute deviation for the doctors are;
Doctor A: 11.8
Doctor B: 12
A data set's mean absolute deviation (MAD) is the average distance between each data value and the mean.
A data set's fluctuation can be described using mean absolute deviation. The mean absolute deviation tells us how "spread out" the values in a data collection are.
<h3>How do we calculate the absolute mean deviation for Doctor A’s data set on glasses?</h3>x |x - Mean|
643 0.9
634 9.9
670 26.1
658 14.1
636 7.9
624 19.9
641 2.9
655 11.1
649 5.1
629 <u>14.9</u>
112.8
From the above information, the mean = 643.9
Thus, the mean absolute deviation = 112.80/10
MAD = 11.28
<h3>How do we calculate the absolute mean deviation for Doctor B’s data set on glasses?</h3>
x |x - Mean|
651 14.4
625 11.6
622 14.6
624 12.6
631 5.6
621 15.6
653 16.4
647 10.4
646 9.4
646 <u>9.4</u>
120
The mean absolute deviation = 120/10
= 12
