To find the mean absolute deviation (MAD), we need to find the average of the likes given to each photo.
Adding up the number of likes: 10 + 13 + 15 + 15 + 17 + 29 = 99.
To find the average, we divide the total sum by the number of numbers: 99/6 = 16.5.
Now, we find the difference between each number of likes and the average:
|10 - 16.5| = 6.5
|13 - 16.5| = 3.5
|15 - 16.5| = 1.5
|15 - 16.5| = 1.5
|17 - 16.5| = 0.5
|29 - 16.5| = 12.5
Rounding each difference to the tenths place, we get:
6.5, 3.5, 1.5, 1.5, 0.5, 12.5.
Therefore, each photo is about 6.5, 3.5, 1.5, 1.5, 0.5, and 12.5 likes away from the average (MAD).
Bethany has a photo website where she places photos she has taken. Below is how many likes each of her current photos were given:
10, 13,15,15,17,29
About how many likes away is each photo from the average (round to the tenths place)? Hint: This is your MAD.
