“There are three types of lies. Lies, damn lies, and Statistics” Graphing “There are three types of lies. Lies, damn lies, and Statistics” -Benjamin Disraeli

Skittles!!! Do all skittles bags have an even number of colors? Are there more red skittles than any other color, etc.

Data Tables are a neat and organized way to collect data Graphs allow you to easily show the data in a way that people can draw conclusions easily. Statistics are mathematical tests that can tell us useful things about data Example: the mean, median, mode Standard Deviation: the mean of the mean

Skittle Colors Trial RED PURPLE YELLOW GREEN ORANGE Other

How to calculate Mean: add up all the numbers from a column and divide by how many numbers there are Median: Line up all the numbers in order and then pick the one in the center Mode: The most repeated number Standard deviation: the mean of the mean

Our Activity Step 1: Divide your candy by color and create a Table Step 2: Build a graph to compare the amount of each candy (GRAPH 1) Step 3: Talk to your neighbor table; Create a comparative graph using their data and yours (GRAPH 2) Step 4: As a Whole class; Create a graph to compare all the colors in the WHOLE bag (GRAPH 3)

Our Activity Continued: Step 5: Calculate the Mean, Median and Mode for you data; based on your LAST graph (the Circle one) Step 6: Write a Conclusion paragraph describing your findings
