# Find the Mean

Find the Mean
To find the mean of a given set of data, you need to add up all data and divide by the number of pieces of the data.

Example:

1). Marsha earned \$15, \$20, \$10, \$12, \$20, \$16, \$80, \$18, and \$25 babysitting. What is the mean amount she earned?

Step1: Add up all the money she earned:

\$15+\$20+\$10+\$12+\$20+\$16+\$80+\$18+\$25= \$216.00

Step 2: Divide \$216.00 by the number of pieces of data

216/9= \$24

# Math Limerick

Question: Why is this a mathematical limerick?

( (12 + 144 + 20 + 3 Sqrt[4]) / 7 ) + 5*11 = 92 + 0 .

A dozen, a gross, and a score,
plus three times the square root of four, divided by seven, plus five times eleven, is nine squared and not a bit more.

---Jon Saxton (math textbook author)

Presentation Suggestions:
Challenge students to invent their own math limerick!

The Math Behind the Fact:
It is fun to mix mathematics with poetry.
