Answer:
The mean for the data plot is 5. The absolute deviation for the data point at 7 is 2.
Explanation:
For your reference,
Mean (the average) - the sum of all data values divided by the number of the data values.
Deviation - the difference between a data value in a set and the mean of the set.
Absolute value - the distance (a positive quantity) of any value on a number line from zero.
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Here , we have Mean for data plot as 5 . We need to find absolute deviation for data point at 7 .
∴ Absolute Deviation = | Data point - Mean| ⇒ | 7 - 5 | = 2
