Understanding Line and Dot Plots

The video from MooMoMath introduces line and dot plots, explaining how they represent data using x's and dots, respectively. An example is provided using a survey of 20 students about the number of calls made in a day. The video guides viewers through finding the minimum and maximum values, drawing a number line, plotting data points, labeling the number line, and titling the plot.

What is the primary difference between line plots and dot plots?

• Line plots use dots, while dot plots use x's.

• Line plots use x's, while dot plots use dots.

• Line plots use numbers, while dot plots use letters.

• Line plots and dot plots are the same.

How many students did Hayden survey about their phone calls?

• 10 students

• 25 students

• 20 students

• 15 students

What is the maximum number of calls made by a student in Hayden's survey?

• 5 calls

• 9 calls

• 6 calls

• 8 calls

What is the first step in creating a dot or line plot from Hayden's data?

• Label the number line.

• Count the number of students.

• Find the minimum and maximum values.

• Draw a number line from 0 to 10.

What should you do after plotting each observation on the number line?

• Erase the number line.

• Cross off the number as you plot them.

• Add more numbers to the line.

• Change the title of the plot.
