Practice Standard Deviation in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The standard deviation measures the average distance of data values from the mean, giving a typical spread around the center.
The typical distance from the average. Low SD = clustered. High SD = spread out.
Example 1
mediumFind the population standard deviation of \{2, 4, 4, 4, 5, 5, 7, 9\}.
Example 2
hardFind the sample standard deviation of \{10, 12, 23, 23, 16, 23, 21, 16\}.
Example 3
mediumFind the population standard deviation of \{6, 2, 3, 1\}.
Example 4
mediumCompare the population standard deviations of A = \{4, 4, 4, 4\} and B = \{2, 4, 4, 6\}.
