Constructing a Scatter Plot

This video tutorial teaches how to construct and analyze scatter plots. It begins with an introduction to scatter plots and the coordinate plane, explaining the x-axis and y-axis. The tutorial then covers graphing points using x and y coordinates, highlighting common mistakes. It introduces bivariate data and explores relationships between variables, using homework completion and test grades as an example. The video guides viewers through creating a scatter plot from collected data, including labeling axes and determining scales. Finally, it analyzes the scatter plot to identify trends, concluding that more homework correlates with higher test grades.

What is the first step in graphing a point on a coordinate plane?

• Identify the x-coordinate

• Determine the scale

• Label the axes

• Identify the y-coordinate

What is bivariate data?

• Data collected from multiple surveys

• Data collected from unrelated variables

• Data collected from a single variable

• Data collected from two related variables

How is a scatter plot useful?

• It organizes data into categories

• It calculates the average of data points

• It provides a visual representation of data relationships

• It shows the exact values of data points

What should you do first when creating a scatter plot?

• Plot the data points

• Label the axes and determine the scale

• Draw a line of best fit

• Calculate the mean of the data

What is the range of the x-axis in the scatter plot example?

• 0 to 100

• 0 to 50

• 0 to 10

• 0 to 5

What is the range of the y-axis in the scatter plot example?

• 0 to 100

• 0 to 50

• 0 to 70

• 0 to 10

What does the scatter plot suggest about homework and test grades?

• Homework completion does not affect test grades

• More homework leads to higher test grades

• There is no relationship between homework and test grades

• More homework leads to lower test grades
