The change in the test scores that I see in the graph is 0 siblings the test scores are between 80 and 90, If 1 siblings the test scores are between 80 and 100, If 2 siblings the test scores are between 78 and 88, If 3 siblings the test scores are between 73 and 100, If 4 siblings the test score is about 88, Tenney wanted to see if there was any relationship between the number of siblings that a student has and their score on the test using data shown in the scatter plot. No, relationship between the number of siblings that a student has and their score on the test, Describe the change in test scores that you see in the graph.

Tenney wanted to see if there was any relationship between the number of siblings that a student has and their score on the test The data are shown in the scatter plot.Į. Two data sets have no association when there is no relationship between their data values. Yes, I think the relation between test scores and social media time appears nonlinear as the slope is negative, then there is a negative nonlinear relationship, i.e., as time increases the other variable test score decreases. Do you think the relation between test scores and social media time appears linear? Explain. The data are shown in the scatter plot.Īs the social media time increased the test score decreased.ĭ. Tenney also tracked the number of hours students spent on social media sites and the scores they got on the test. Describe the change that you see in the graph.Īs the _ increases, the _ decreases.Īs the social media time increases, the test score decreases, The data are shown in the scatter plot.Ĭ. Two data sets have a negative association if one set of data values increases while the other decreases. Yes, I think the relation between test scores and study time appears linear,Īs the study time increases, the test score increases, In the graph the data points lie roughly along a line therefore the data set displays a linear association. Do you think the relation between test scores and study time appears linear? Explain. When the data seem to follow a pattern resembling anything other than a line, the data set either displays a nonlinear association or no association at all. When data points lie roughly along a line, the data set displays a linear association. The change that I see in the graph is as the study time increases, the test score increases.ī. Describe the change that you see in the graph.Īs the _ increases, the _ increases.Īs the study time increases, the test score increases, Tenney’s class is shown in a scatter plot.Ī. Two data sets have a positive association when their data values increase together or decrease together.Ī scatter plot is a graph with points plotted to show a possible relationship between two sets of data. That’s why there is not a constant rate of chang for the number of hours studied and the test scores.Īn association is the description of the relationship between two data sets. The number of hours for study time increased, But they did not studied well so did not score well,Īs the number of hours for study time increased, But they did not studied well so did not score well, Turn and Talk Why do you think there is not a constant rate of change for the number of hours studied and the test scores? Graphed the data in the table as shown above, As the study time increased the test score also increased. Tenney tracked the number of hours that each student studied and the scores they got on the test. The students had 3 weeks to study for the test, and Describe the graph.Īs the study time increases even the test score increased, The students had 3 weeks to study for the test, and Mrs. I Can construct a scatter plot, determining whether an association is positive or negative, strong or weak, and nonlinear or linear.
