To find the mean deviation, first, calculate the mean of the numbers, which is 10. Then, find the absolute deviations from the mean ({|6-10|, |7-10|, |10-10|, |12-10|, |13-10|, |4-10|, |12-10|, |16-10|}). The mean deviation is the average of these values: 3.75.

FAQs & Answers

  1. What is mean deviation in statistics? Mean deviation is the average of the absolute differences between each data point and the mean of the data set, showing how spread out the data is.
  2. How do you calculate the mean deviation? To calculate mean deviation, first find the mean of the data set, then compute the absolute deviations of each value from the mean, and finally find the average of those absolute deviations.
  3. What is the difference between mean deviation and standard deviation? Mean deviation uses absolute values of deviations from the mean, while standard deviation uses squared deviations, making standard deviation more sensitive to outliers.
