Example 1: Graphing a Scatter Plot from Given Data The table shows the number of cookies in a jar from the time since they were baked. Graph a scatter plot using the given data. Use the table to make ordered pairs for the scatter plot. The x-value represents the time since the cookies were baked and the y-value represents the number of cookies left in the jar. Plot the ordered pairs.

A correlation describes a relationship between two data sets. Example 2: Describing Correlations from Scatter Plots There is a _______________ correlation between the two data sets. As the average daily temperature increased, __________________________ Describe the correlation illustrated by the scatter plot.

Example 3A: Identifying Correlations The average temperature in a city and the number of speeding tickets given in the city Identify the correlation you would expect to see between the pair of data sets. Explain. The number of people in an audience and ticket sales A runner ’ s time and the distance to the finish line

Example 4: Matching Scatter Plots to Situations Choose the scatter plot that best represents the relationship between the age of a car and the amount of money spent each year on repairs. Explain. Graph A Graph B Graph C

Example 5: Fund-Raising Application The scatter plot shows a relationship between the total amount of money collected at the concession stand and the total number of tickets sold at a movie theater. Based on this relationship, predict how much money will be collected at the concession stand when 150 tickets have been sold. Draw a trend line and use it to make a prediction. Draw a line that has about the same number of points above and below it. Your line may or may not go through data points. Find the point on the line whose x-value is 150. The corresponding y-value is 750. Based on the data, $750 is a reasonable prediction of how much money will be collected when 150 tickets have been sold. You can graph a line on a scatter plot to help show the relationship. This line, called a trend line, is used to make predictions.
