is it possible to have a standard deviation of 435,000 for some days set? explain why or why not.
Homework Answers
Solution: Standard deviation is the deviation of the set of data from its mean. It is possible to have a standard deviation of 435,000 because it explains the average deviation of the set of numbers from its mean. For example: if we are interested in finding the standard deviation of the top wealthiest people of the world, we expect to see large number's and there is every possibility of seeing a huge standard deviation in such case.
