Cara collected data from 10 students about what their favorite number was between 1 and 10.
the students responses were: 1, 2, 2, 4, 5, 6, 6, 8, 8, 8
what is the absolute deviation?
a) 2.2
b) 5
c) 22
d) 50

Option A - 2.2

Step-by-step explanation:

Given : Data of 10 students

The students responses were: 1, 2, 2, 4, 5, 6, 6, 8, 8, 8

To find : The absolute deviation

Solution :

Step 1: We calculate the mean.

Step 2: Then we calculate how far away each data point is from the mean using positive distances these are known as absolute deviations.

Data pointDistance from mean

 1                        |5-1| =4

 2                       |5-2| =3

 2                       |5-2| =3

 4                       |5-4| =1

 5                       |5-5| =0

 6                       |5-6| =1

 6                       |5-6| =1

 8                       |5-8| =3

 8                       |5-8| =3

 8                       |5-8| =3

Step 3: Add the deviations together.

Step 4: Finally Divide the sum by the number of data points to get mean of absolute deviation.

Therefore,Option A is correct the mean absolute deviation is 2.2.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
