The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset is.
The given data in the problem is;
Two months ago,
The mean daily rainfall in a local city was 9. 4 cm.
The mean absolute deviation was 3. 5 cm
Last month
The mean daily rainfall in that city was 11. 5 cm
The mean absolute deviation was 1. 6 cm.
We can see that there was less variation last month than the month before since the mean absolute deviation is a measure of variance.
Hence Last month the amount of rain that fell each day varied about the same as the month before is the right statement about the rainfall, Option c is correct.
