Question

Find the mean absolute deviation. Round to the tenth

Answer 1

1) 1.8 round to tenths

Explanation:

To find the mean absolute deviation we follow these steps:

1. Find the mean value by adding all data values and dividing by number of data values
2. Find the absolute value of the difference between each data value and the mean: | data value – mean. |
3. Divide the sum of the absolute values of the differences by the number of data values

1) 4,5,10,8,4,8,7,6

step 1

4+5+10+8+4+8+7+6 / 8 = 6.5

Mean (μ): 6.5

step 2

|4-6.5| + |5-6.5| + |10-6.5| + |8-6.5| + |4-6.5| + |8-6.5| +|7-6.5| + |6-6.5| = 14

step 3

14 / 8 = 1.75

Repeat these steps for other parts.
