Which of the following mean absolute deviations belong to the database with the least variation negative 0.5 10.2 1.01 0.01

The mean absolute deviation is a measure of the average distance between each data point and the mean of the dataset. In this case, a smaller mean absolute deviation would indicate less variation in the dataset.

Of the given values, the mean absolute deviation of 0.01 is the smallest, so this value likely belongs to the dataset with the least variation.
