Minute to Win it Data

Mean:  The Average.  Add up all of the digits to get a grand total and then divided that answer by the total number of pieces of data.

Median:  The Middle.  Line up the values in order from least to greatest.  The middle value is the median.  If there are two in the middle, add them together and divide by 2.

Mode:  The Most.  The value that shows up the most often.  You can have more than one mode if more than one value shows up the most.

Range:  The Span.  Subtract the smallest value from the largest value.  You should have one answer not "from x to y."

Homework:  Determine the mean, median, mode and range for each data set from your math class.  Expect decimals in most means!

Class data:

Red class.  (please note that there is one less piece of data in the second two activities)

White class.

Blue class.

Green class.

Good luck, use a calc, and have fun!  Pictures coming soon!
