How do you find the standard deviation of a data set of numbers? I know the median, and the upper and lower quartile numbers. I am making a box plot and need to know how to graph that on a box plot as well. For example let us say the numbers are 1,2,3,4,5,6,7,8,9. How would you find the standard deviation?
Suppose a normally distributed set of data has a mean of 172 and a standard deviation of 15. Use the 68-95-99.7 rule to determine the percent of scores in the data set expected to be between the scores 142 and 187. Give your answer in decimal form and keep all decimal places throughout your calculations and in your final answer.
