No association scatter plot pdf#

The scatter plot shows the basketball shooting results for 14 players. We would see that Bob’s height eventually stops increasing if the data continued. (Explore Activity 1)ĭescribe the association between Bob’s age and his height. Texas Go Math Grade 8 Lesson 14.1 Guided Practice Answer Keyīob recorded his height at different ages. Taller students are likely to be oLder students and would therefore be more likely to read at a higher level. Describe the association and give a possible reason for it. The plot shows the reading level and height for 16 students in a district. It might happen that there will not be buyers. then the number of buyers will be smaller than it has been. What If? Based on the association shown in the scatter plot, what might happen if Susan increased the price to $14?Īs the price increases, the number of buyers decreases. Because the data points do not lie along a line, the association is nonlinear. Describe the association between price and the number of buyers.Īs price increases, the number of buyers decreases. The scatter plot shows how many of the 20 said “yes” at a given price. Susan asked 20 people if they would buy a new product she developed at each of several prices. If the geyser erupts after an 80-minute interval, the range of possible duration times for which the point on the scatter plot would not be considered an outlier is between 3 and 5 minutes. Use a given scatter plot to find out a range of possible duration. Give a range of possible duration times for which the point on the scatter plot would not be considered an outlier. Suppose the geyser erupts after an 80-minute interval. Based on that, the geyser which erupts for 2.2 minutes after a 75-minute interval will present a data point that is very different from the rest of the data in the set. This set is pointed between intervals of 40 and 60 minutes, and they last between 1.5 and 2.5 minutes. This point will be an outlier because it will not be a part of a set of closely grouped data.

If the geyser erupts for 22 minutes after a 75-minute interval, this point would not lie in one of the clusters. Try to make a point that is given in a scatter plot and make conclusions based on that. Would this point lie in one of the clusters? Would it be an outlier? Explain your answer. Suppose the geyser erupts for 2.2 minutes after a 75-minute interval. Describe any outliers you see in the scatter plot. What do the clusters tell you about eruptions of Old Faithful?Ĭ. Describe any clusters you see in the scatter plot.ī. The data show the length of time between eruptions (interval) and how long the eruption lasts (duration).Ī. She uses the data to create a scatter plot. An outlier is a data point that is very different from the rest of the data in the set.Ī scientist gathers information about the eruptions of Old Faithful, a geyser in Yellowstone National Park. Data may cluster around a point or along a line. Students who spent more hours studying will have better test results.Ī cluster is a set of closely grouped data. The grade associated with studying for 10 hours would follow this trend. Justify Reasoning Do you think that studying for 10 hours would greatly increase a student’s grade? Trend shows positive association which means that both data sets increase together. You can make a scatter plot which will help you to decide what trend do you see in the data. Graph hours spent studying as the independent variable and test grades as the dependent variable. Make a prediction about the relationship between the number of hours spent studying and test grades.ī. The final question on a math test reads, “How many hours did you spend studying for this test?”The teacher records the number of hours each student studied and the grade the student received on the test.Ī. A scatter plot is a graph with points plotted to show the relationship between two sets of data. You can graph bivariate data on a scatterplot. Bivariate data are used to explore the relationship between two variables. Recall that a set of bivariate data involves two variables.
