Answer:
1) 1.8 round to tenths
Step-by-step explanation:
To find the mean absolute deviation we follow these steps:
- Find the mean value by adding all data values and dividing by number of data values
- Find the absolute value of the difference between each data value and the mean: | data value – mean. |
- 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.
