Graph A The age of the car cannot be negative.Ĭhoose the scatter plot that best represents the relationship between the age of a car and the amount of money spent each year on repairs. Graph A Graph B Graph CĬhoose the scatter plot that best represents the relationship between the age of a car and the amount of money spent each year on repairs. As the number of times you sharpen your pencil increases, the length of your pencil decreases.ġ6 Additional Example 4: Matching Scatter Plots to SituationsĬhoose the scatter plot that best represents the relationship between the age of a car and the amount of money spent each year on repairs. the number of times you sharpen your pencil and the length of your pencil You would expect negative, non-linear correlation. As the number of members in a family increases, more food is needed, so the grocery bill increases too.ġ5 Check It Out! Example 3c Identify the type of correlation you would expect between the pair of data sets. the number of members in a family and the size of the family’s grocery bill You would expect positive, linear correlation. The temperature in Houston has nothing to do with the number of cars sold in Boston.ġ4 Check It Out! Example 3b Identify the type of correlation you would expect between the pair of data sets. the temperature in Houston and the number of cars sold in Boston You would except no correlation (non-linear). As a runner’s time increases, the distance to the finish line decreases.ġ3 Check It Out! Example 3a Identify the type of correlation you would expect between the pair of data sets. a runner’s time and the distance to the finish line You would expect a negative, linear correlation. Identify the correlation you would expect between the pair of data sets. As ticket sales increase, the number of people in the audience increases.ġ2 Additional Example 3C: Identifying Correlations the number of people in an audience and ticket sales You would expect a positive, linear correlation. The number of speeding tickets has nothing to do with the temperature.ġ1 Additional Example 3B: Identifying Correlations the average temperature in a city and the number of speeding tickets given in the city You would expect no correlation (non-linear). ![]() There is a positive, linear correlation between the two data sets.ġ0 Additional Example 3A: Identifying Correlations As the years passed, the number of participants in the snowboarding competition increased. There is a positive, linear correlation between the two data sets.ĩ Check It Out! Example 2 Describe the correlation illustrated by the scatter plot. As the average daily temperature increased, the number of visitor increased. There are three types of correlations between data.Ĩ Additional Example 2: Describing Correlations from Scatter Plotsĭescribe the correlation illustrated by the scatter plot. The correlation can help you analyze trends and make predictions. A graph may show the correlation between data. Plot the ordered pairs.Ħ A correlation (association) describes a relationship between two data sets. The x-value represents the individual games and the y-value represents the points scored in each game. Game 1 2 3 4 Score 6 21 46 34 Use the table to make ordered pairs for the scatter plot. Graph a scatter plot using the given data. Plot the ordered pairs.ĥ Check It Out! Example 1 The table shows the number of points scored by a high school football team in the first four games of a season. ![]() The table shows the number of cookies in a jar from the time since they were baked. The x-value represents the time since the cookies were baked and the y-value represents the number of cookies left in the jar. Use the table to make ordered pairs for the scatter plot. A scatter plot is an effective way to display some types of data.ģ Additional Example 1: Graphing a Scatter Plot from Given Data Non-LinearĢ A scatter plot is a graph with points plotted to show a possible relationship between two sets of data. Positive correlation (association) negative correlation (association) no correlation (association) trend line Outlier Linear vs. 1 Vocabulary scatter plot Correlation (association)
