A scatter plot is a graph with points plotted to show a relationship between two sets of data.
Correlation describes the type of relationship between two data sets.

Positive correlation: both data sets increase together.
Negative correlation: as one data set increases, the other decreases.
No correlation: changes in one data set do not affect the other data set.

Use the given data to make a scatter plot of the weight and height of each member of a basketball team, and describe the correlation.
Additional Example 1: Making a Scatter Plot of a Data Set
Use the table to make ordered pairs for the scatter plot.
The x-value represents the height of each member and the y-value represent their weight.
Plot the ordered pairs. There is a positive correlation between the two data sets.

Make a scatter plot of the data, and draw a line of best fit. Then use the data to predict how much a worker will earn in tips in 10 hours.
Additional Example 2: Using a Scatter plot to Make Predictions
Tips earned may be dependent on the number of hours worked.
Step 1: Make a scatter plot. Let hours worked represent the independent variable x and tips earned represent the dependent variable y.

Step 3: Make a prediction. According to the graph, working 10 hours will earn about $24 in tips.
Find the point on the line whose x-value is 10. The corresponding y-value is about 24.
