Creating dot plots

The topic  appears under the 6th Grade Math Mission. This exercise practices the creation of dot plots from raw information.

Types of Problems
There are two types of problems in this exercise:


 * 1) Create the dot plot from the list of raw data: This problem provides a list of raw information and a number line. The student is asked to use the number line to create a dot plot of the given information.Cdp1.png
 * 2) Label the axis: This problem provides a completed dot plot and an explanation of how it was created. The student is asked to select the correct way to label one of the axes.Cdp2.png

Strategies
The prerequisite knowledge for this problem is basic statistical displays and ability to label information in charts and graphs.
 * 1) The manipulative is not great, it sometimes makes dots half appear when a certain value is overshot.
 * 2) When creating a plot it can be easier to choose the smallest value on the number line, count the times that occurs, and proceed in a logical order.
 * 3) The vertical axis in a dot plot is always a count of how many times something occurs, where as the horizontal axis is the value of some variable.
