What is a Line Plot?
What is a Line Plot? is a Grade 4 math skill in enVision Mathematics, Chapter 11: Represent and Interpret Data on Line Plots. Students learn how to read and create a line plot by placing Xs or dots above a number line to show how often each data value occurs in a data set.
Key Concepts
Property A line plot is a graph that displays data using marks (such as X’s or dots) placed above a number line. Each mark represents one data value, and multiple marks stacked above the same number show how often that value occurs. In this way, a line plot makes it easy to see the frequency of each value, as well as patterns in the data, such as which values appear most often, which appear least often, and how the data are spread out along the number line.
Examples A line plot titled "Number of Books Read in a Month" has a number line from $0$ to $10$. If three students read $5$ books, there would be three X''s above the number $5$. A line plot showing "Heights of Seedlings (in cm)" might have a number line from $2$ to $8$. A seedling that is $4\frac{1}{2}$ cm tall would be represented by an X above the $4\frac{1}{2}$ mark on the number line.
Explanation A line plot is a simple way to organize and see data quickly. It uses a number line to show the range of values in a set of data. Above the number line, X''s or dots are used to mark how many times each value occurs. This makes it easy to see which values are most common, identify the highest and lowest values, and understand the overall distribution of the data.
Common Questions
What is a line plot in math?
A line plot is a type of graph that displays data using Xs or dots placed above a number line. Each mark represents one data point, showing how many times each value occurs.
How do you read a line plot?
Look at the number line to find data values. Count the Xs or dots above each value to see how many times that value appears in the data set.
How do you create a line plot?
Draw a number line scaled to fit your data range. For each data value, place an X above the corresponding number. Stack Xs vertically when a value appears multiple times.
What can you learn from a line plot?
A line plot shows the distribution of data, including which values appear most often, the range of values, and any clusters or gaps in the data.
What chapter introduces line plots in enVision Mathematics Grade 4?
Line plots are introduced in Chapter 11: Represent and Interpret Data on Line Plots in enVision Mathematics Grade 4.
