Scatter Graphs Introduction

What is the primary purpose of a scatter graph?

• To display the frequency of data points

• To compare three or more variables

• To calculate the average of a data set

• To show the relationship between two sets of data

In the example provided, what are the two variables being compared on the scatter graph?

• The color of the dog and the frequency of its bark

• The weight of the dog and the speed of its run

• The size of the dog and the loudness of its bark

• The age of the dog and the length of its tail

What is the first step in plotting a point on a scatter graph?

• Find the value on the X-axis

• Label the axes

• Draw a line from the Y-axis

• Calculate the average of the data

Why is the scatter graph incomplete with only four data points?

• The axes are not labeled

• It doesn't show a clear correlation

• The points are not connected

• It lacks a title

What should you do after plotting the points on the scatter graph in the practice question?

• Connect the points with a line

• Erase the points and start over

• Pause the video and review your work

• Add more data points
