... standard deviation, a measure of the spread of the data, will not change. When each value in a data set is transformed by multiplication by a particular constant, both the mean and the standard deviation will change. In this activity, students explore these transformations and draw conclusions about ...

... Example Here is another example. Suppose that I roll a fair die with faces numbered from 1 to 6. If the number shown is n, I then toss a fair coin n times and count the number of heads. What is the expected value of the number of heads? Let N be the random number shown on the die, and X the number ...

The variance is the second central moment. The skewness and kurtosis are essentially the third and fourth central ...
