Scatter Plots and Predictions

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional grid.

Front

What is an outlier in a scatter plot?

Back

An outlier is a point that is far outside the main cluster of points/ordered pairs in a scatter plot.

Front

How can you use a scatter plot to make predictions?

Back

You can use the trend line in a scatter plot to estimate values for one variable based on the values of another variable.

Front

What does the line of best fit represent in a scatter plot?

Back

The line of best fit represents the trend in the data, showing the general direction that the data points follow.

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

If a player attempts 60 free throws and is expected to make 35, what is the success rate?

Back

The success rate is approximately 58.3% (35 made out of 60 attempts).

Front

How do you identify the slope of a line from a scatter plot?

Back

The slope of a line can be identified by calculating the change in y over the change in x (rise over run) between two points on the line.

Front

What does a positive slope indicate in a scatter plot?

Back

A positive slope indicates that as one variable increases, the other variable also increases.

Front

What does a negative slope indicate in a scatter plot?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

How can you determine the number of chapters in a book with 180 pages using a scatter plot?

Back

You can use the trend line to estimate the number of chapters corresponding to 180 pages.
