Create or find a unique data set with 5 different values (these are your "original data values").  Be sure to state what the data values represent (e.g. number of emails per day, time spent commuting, hours watching tv,...)

Initial Post:

• Calculate and state the mean, median, range and standard deviation of your data set
• Clearly and fully answer the following questions

1. If you increase the highest original data value by 5 and decrease the lowest original data value by 1, what measure changes; the mean, median, both, or neither?  Why?
2. If you add 10 to each original data value, what measure changes; the standard deviation, range, both, or neither?  Why?
3. If you multiply each original data value by 3, what measure changes; the standard deviation, range, both, or neither?  Why?
