To find the mean deviation from the mean for the data set 6, 7, 10, 12, 13, 4, 12, 16, first calculate the mean: (6+7+10+12+13+4+12+16)/8 = 10. Next, find the absolute deviation of each data point from the mean, sum them up, and divide by the number of data points: (|6-10| + |7-10| + |10-10| + |12-10| + |13-10| + |4-10| + |12-10| + |16-10|)/8 = (4+3+0+2+3+6+2+6)/8 = 26/8 = 3.25.

FAQs & Answers

  1. What is mean deviation used for? Mean deviation measures the average deviation of data points from the mean, helping to understand data variability.
  2. How do you find the mean of a data set? The mean is calculated by adding all data points together and dividing by the number of points.
  3. What is the difference between mean deviation and standard deviation? Mean deviation uses absolute values, while standard deviation considers squared differences from the mean.
  4. Can mean deviation be negative? No, since it is based on absolute differences, mean deviation is always zero or a positive value.
