Compute the mean, median, and mode for any set of data.

What happens to the mean, median, and mode if you add 0.7 to each element of the data? What happens to these values if you subtract 0.5 from each element of the data?

If the mean, median, and mode of the data set abcd are 16, 11 and 4, what are the mean, median, and mode of the data set a + xb + xc + xd + x, where x is any real number?

Extension
Describe what happens to the mean, median, and mode of a data set when you multiply each data point by a number k.
