Dot Plots Worksheets
A dot plot is a primitive form of a typical graph. It represents each piece of data with individual dots. They are very helpful for representing data that consist of only one variable. In some cases, they are much more useful than a bar or line graph when you are trying to make a point about smaller values within data sets. Conversely, they do not lend themselves well to more strenuous data samples. These are very efficient graphic representations that offer accurate comparisons between different simple comparisons. By having the data right in front of you, the reader or observer can get a succinct impression of the contrast you are creating. If you are trying to conserve ink in your printer or color in your markers, they can often be the solution to your predicament. They are often helpful to establish a relationship between two variables in a single dimension as well. We will use the worksheets below to bring you up to speed with this form of graphical representation.

- Breakfast Lesson- Many people take a wide array of time to consume their entire breakfast. The amount of time differs based on if they are morning or night people. We took a quick poll on fifteen different students to find the amount of time(in minutes) that they took to eat breakfast and found the following data: 5, 8, 6, 13, 7, 10, 13, 7, 12, 8, 9, 11, 8, 10, 9, 13, 7, 5, 13. Create a dot plot to display the amount of time it takes these students to eat their breakfast.
- Guided Lesson - Jessica is charge of 20 office buildings. Each building has a different number of workers that reside in each building. The data below shows the occupancy of each building.
- Guided Lesson Explanation - Our first step is to get the data arranged in ascending order. Now we to organize this data into a frequency table to determine the frequency of the data points. Since the data seems to differ by 10s, we will create a frequency table by 10s starting at the lowest level of tens (20s) to the upper most level of data (90s).
- Practice Worksheet - Juan is collecting fish in traps for an experiment. The table below shows the number of fish caught in the traps. Make a dot plot to show the results.
