## Texas Go Math Grade 4 Lesson 17.3 Answer Key Dot Plots

Essential Question

How do you make a dot plot with whole numbers and fractional data?
A dot plot is a graphical display of data using dots.
Example: Minutes To Eat Breakfast.
A survey of “How long does it take you to eat breakfast?” has these results:
Minutes: 0    1    2    3    4    5    6    7    8     9   10    11    12
People:   6    2    3    5    2    5    0    0    2     3    7      4      1
This means that 6 people take 0 minutes to eat breakfast (they probably had no breakfast!), 2 people say they only spend one 1-minute having breakfast, etc. And here is the dot plot: Unlock the Problem

A dot plot is a graph that shows the frequency of data along a number line.

Example 1
Scott is training to run a half-marathon. He recorded the distances he ran in a table. Use the data in the table to make a dot plot. STEP 1
Order the data from the least to the greatest distance.
4, 4, _________, _________, _________, _________, _________, _________,
_________, _________, _________, _________, _________, _________, _________

Draw a number line. Label it with the distances. Write a title below the number line to describe the data.

Label the distances on the number line from the least value of the data to the greatest. The data points for this dot plot will be
_________, _________, _________, _________, _________, and _________.
Step 1: Order the data from the least to the greatest distance.
4, 4, 5, 5, 7, 7, 7, 8, 8, 8, 9, 9, 9, 9, 9.
Draw a number line. Label it with the distances. Write a title below the number line to describe the data.

Answer: The total distance points representation in below diagram: Explain why a dot plot is a useful way to organize and present data.
A dot plot is similar to a histogram that displays the number of data points that fall into each category or value on the axis. You can use a dot plot to compare your data to a reference group, identity outliers, and see trends.

Example 2
