mode: 3

median: 3

___________________________

mean:

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 2 = 8

5 x 1 = 5

6 x 1 = 6

1 + 4 + 9 + 8 + 5 + 6 = 33 ÷ 10 = 3.3

_____________________________

mean: 3.3

____________________________

Interquartile Range: 4 - 2 = 2

___________________________

Range: 6 - 1 = 5

____________________________

Mean Absolute Deviation:

3.3 - 1 = 2.3

3.3 - 2 = 1.3

3.3 - 2 = 1.3

3.3 - 3 = 0.3

3.3 - 3 = 0.3

3.3 - 3 = 0.3

3.3 - 4 = 0.7

3.3 - 4 = 0.7

3.3 - 5 = 1.7

3.3 - 6 = 2.7

____________________________

1.3 · 2 = 2.6

0.3 · 3 = 0.9

0.7 · 2 = 1.4

____________________________

2.3 + 2.6 + 0.9 + 1.4 + 1.7 + 2.7 = 11.6/10 = 1.16

____________________________________

So your mean absolute deviation would be 1.16 :)!

Answer:

the answer is 1.16 shirts

Step-by-step explanation:

the mean absolute deviation is found by finding the average of the difference between each data point and the mean of the data.

1st...find the mean of the data by adding all the numbers according to the data plotted and dividing the by the numbers listed; which in this case is 10

1 +2+ 2+ 3+ 3+ 3+ 4+ 4+ 5+ 6 = 3.3

mean is 3.3

then find the difference between the mean and each data point

Data Point =                       1      2     2      3     3       3      4      4     5      6

Difference from mean = 2.3    1.3   1.3  0.3  0.3   0.3   0.7    0.7   1.7   2.7

Find the average of these differences by adding the (differences from Mean) by 10

<u>2.3  + 1.3  + 1.3  + 0.3  + 0.3  + 0.3  + 0.7  + 0.7 +  1.7 + 2.7</u>

                                             10

the mean absolute deviations is 1.16 shirts

X + y = -10
-3x -y = 2
We'll try with x as a small number and y with a big number to try and balance it out.
-3 - 7 = 10
9 - 7 = 2
X = -3
Y = -7
Hope this helps! :)

1. Rename the mixed numbers with common denominators
2. Add the mixed numbers together to get 15 4/6
3. Subtract the sum from 26 to get 10 1/2
4. Since the only term left on the left is k so k=10 1/2
