Dot Plots and Histograms
Grade 6 · Math · Statistics and Data · Nova Scotia, Canada
Lesson Summary
Dot plots show individual data points, while histograms group data into intervals to show the shape of a distribution.
Explanation
A dot plot uses dots stacked above a number line to show each data value. It is great for small data sets because you can see every individual piece of data. A histogram uses bars to show how many data points fall into each range, or interval. For example, you might group test scores into intervals of 60-69, 70-79, 80-89, and 90-100. Histograms are better for large data sets because they show the overall shape and spread of the data at a glance.
Practice Questions
Q1: When would you use a dot plot instead of a histogram?
Answer: When you have a small data set and want to see every individual value.
Q2: A histogram shows the tallest bar at the 80-89 interval. What does this tell you?
Answer: More data points fall in the 80-89 range than in any other interval.
Q3: On a dot plot, the number 7 has 5 dots above it. What does that mean?
Answer: The value 7 appears 5 times in the data set.
