1) Write a Statistical Question

Remember, in order for a question to be a statistical question, you need to be able to gather more than 1 data sample.

Example: What hair color do the students in Ms.  Stebelton's 5th block math class have?

NOT a statistical question: What color are Ms. Stebelton's shoes?

The first question can have more than 1 answer whereas with the second question it only has 1 answer. The first question addresses more than one person/group/thing and the second question only addresses a single person. 

Write your own question:

_______________________________________________________________________________________________________________________________________________________________________________________________________________________

2) Gather Data

1) Walk around the class and ask each of your classmates your statistical question, making sure to record their answers!

2) Once you have your data, set up a frequency table and decide if you will use intervals or single numbers.

Analyze the Data

Analyze the data: calculate the mean (if possible), median (or median interval), and range.

 If you are unable to calculate the mean, please explain why: ______________________________

Mean_________         Median__________    Range__________

Graph the Data

Graph the data as a dot plot, histogram, or box plot, depending on the type of data you collected. Do this using one of the suggested websites or you may create your own on construction paper (It's up to you!). Label the graph with a title, and then label the x- and y-axes.
