Carter got the following scores: 90,82,88,78,93
What is the mean absolute deviation?
A- 4.96
B- 12.00
C- 86.20
D- 88.00
my answer is B.
it's D. 88.00
were they right?
no.
the answers switch up, use your brain and tell the answers in words not letters
did I get it right
alright hopefully these are right if thy are not imma gonna fail
Sooo what is it...... 🥲😅😅😅😅✨👀✨
To find the mean absolute deviation, you need to follow these steps:
1. Find the mean: Add up all the scores and divide the sum by the total number of scores.
(90 + 82 + 88 + 78 + 93) / 5 = 431 / 5 = 86.2
2. Subtract the mean from each score to find the deviations:
|90 - 86.2| = 3.8
|82 - 86.2| = 4.2
|88 - 86.2| = 1.8
|78 - 86.2| = 8.2
|93 - 86.2| = 6.8
3. Find the average of the absolute deviations:
(3.8 + 4.2 + 1.8 + 8.2 + 6.8) / 5 = 24.8 / 5 = 4.96
The mean absolute deviation is 4.96, which matches with option A.
