QuestionFind the range, mean, variance, and standard deviation for this data set: $2, 9, 15, 3, 15, 9, 14, 6, 3, 9$.

Studdy Solution
The standard deviation of the data set is approximately4.3.
$$Standard\, deviation = \sqrt{.45} \approx4.3$$So, the range is13, the mean is.5, the variance is.45, and the standard deviation is approximately4.3.
