To find the mean deviation for the data values 5, 3, 7, 8, 4, 9, follow these steps: First, calculate the mean (average) which is 6. Then, find the absolute deviation for each value from the mean and average those deviations. The mean deviation is 1.83.

FAQs & Answers

  1. What is mean deviation in statistics? Mean deviation is the average of the absolute deviations of each data point from the mean of the dataset.
  2. How do you calculate mean deviation? To calculate mean deviation, find the mean of the dataset, compute the absolute deviations from the mean, and then average those deviations.
  3. Why is mean deviation important? Mean deviation provides a measure of dispersion in a dataset, indicating how spread out the values are around the mean.
  4. What is the difference between mean deviation and standard deviation? While both measure dispersion, mean deviation uses absolute values while standard deviation squares the deviations, making them sensitive to outliers.
