Mean Deviation Calculation: First find the mean of the set (3, 10, 10, 4, 7, 10, 5). Mean = (3 + 10 + 10 + 4 + 7 + 10 + 5) / 7 = 7. Then, find the absolute deviations from the mean and average them: (|3-7| + |10-7| + |10-7| + |4-7| + |7-7| + |10-7| + |5-7|) / 7 = 3.57 (approx). Mean Deviation = 3.57.

FAQs & Answers

  1. What is mean deviation in statistics? Mean deviation is a measure of dispersion that calculates the average of the absolute differences between each data point and the mean of the data set.
  2. How do you calculate mean deviation? To calculate mean deviation, first find the mean of the data set, then find the absolute differences between each data point and the mean, and finally, average those absolute differences.
  3. What is the difference between mean deviation and standard deviation? Mean deviation uses absolute differences from the mean, while standard deviation uses squared differences. Standard deviation is more sensitive to outliers.
