Official AP graders will grade your free-response questions. Each of the six free-response questions is scored on a scale of 0 to 4 points, so the total section is out of 24 points. The free-response questions are graded holistically, which means, instead of getting a point or half a point for each bit of correct information you include, graders look at your answer to each question as a "complete package," and your grade is awarded on the overall quality of your answer. The grading rubric for each free-response question is: 4: Complete Response: Shows complete understanding of the problem's statistical components 3: Substantial Response: May include arithmetic errors, but answers are still reasonable and show substantial understanding of the problem's statistical components 2: Developing Response: May include errors that result in some unreasonable answers, but shows some understanding of the problem's statistical components 1: Minimal Response: Misuses or fails to use appropriate statistical techniques and shows only a limited understanding of statistical components by failing to identify important components 0: No Response: Shows little or no understanding of statistical components What does holistic grading mean for you?

Write the equation below. Be sure to define any variables you use. Suppose a sixth elderly man with a knee height of 57 cm. What impact would this have on a the correlation and b the slope of the regression line? Should you use your regression line from Question 13 to predict the height of an elderly man whose knee height is 70 centimeters? If so, do it. Relative abundance is measure on a 1 to 5 scale, where a 5 means five times as many locusts as 1. Interpret the slope of this line in the context of the problem. The correlation between these two variables is If the amount of rainfall were measured in centimeters rather than inches, how would the correlation change? Explain what least-squares means in term of the variables involved.

Would it be appropriate for the scientists to conclude that changes in rainfall are responsible for variations in the relative abundance of red locusts in this region? Why or why not? When the data for the two varieties is combined, the relationship appears to be positive, rather than negative. See below for scatterplot. There is a moderately strong, positive, linear relationship between overall height and knee height. The new person does not fit the pattern established by the original data: his overall height is low for his knee height. This would reduce the correlation and also reduce the slope of the regression line. You should not use this equation to predict the height of a man whose knee height is 70 cm. For every additional inch of rainfall in the wet season, the predicted relative abundance of locusts decreases by The correlation coefficient does not change when the units for either variable are changed, because it is calculated from standard scores, which are independent of units.

Ap Statistics Chapter 6 Test Answer Key
The least-squares line is the line that minimizes the sum of the squared differences between observed relative abundance measurements and relative abundance measurements predicted by the regression equation. Since this was not a controlled experiment, we do not know the impact of any lurking variables on the abundance of locusts. For example, the amount of rainfall in the wet season may be confounded with some other important variable: perhaps the abundance of an animal that preys on the locust is also influenced by rainfall, so it s predation that influences the locust s abundance.
