Your child beckons you for help with math homework. You’ve assisted in every other subject, but the thought of numbers makes you cringe. Since your own school days, you have done little more math than required to balance the checkbook. You look at the page and it doesn’t look like any math book you’ve ever seen. Panic sets in, but then you calm down. It’s in color, looks like things you really use in everyday life, and it’s actually interesting. You wish you had some notes written on the palm of your hand. Fear not! If the last time you opened a math book was before the new millennium, here are a few notes that might bring you up to date-a math "cheat sheet" of sorts. Data and Statistics for Elementary and Middle School Students A set of data can be any group of numbers, but it is usually a group of numbers with something in common. A typical set of data might be the test grades for a class of students or the temperatures for your city for the last 15 days The median of a set of data is the number that falls exactly in the middle when the numbers are rewritten from least to greatest, left to right. If the temperatures in your city at noon each day for the last 15 days were 86°, 87°, 89°, 71°, 87°, 88°, 91°, 87°, 93°, 96°, 95°, 96°, 94°, 99°, 97°, find the median temperature.
