Find the Mean and MAD of the data set: 7, 6, 17, 8, 7, 9

Mean: 9

MAD: 46

Step-by-step explanation:

I will show u how to work out the mean

and the mad so u know

MEAN:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

MAD:

1) To find the mean absolute deviation of the data, start by finding the mean of the data set.

2 )Find the sum of the data values, and divide the sum by the number of data values.

3) Find the absolute value of the difference between each data value and the mean: |data value – mean.

MARK THIS AS THE BRAINLIEST PLEASE

Mean:9

MAD:2.7

Step-by-step explanation:

Mean:7+6+17+8+7+9=54/6=9

MAD: 9-6.3=2.7

(6.3 is the mean absolute deviation)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

what is the question?
