3. A statement is made about correlation. State whether the correlation is positive or negative andwhether the correlation is most likely due to coincidence, a common underlying cause, or a directcause. If there is an underlying cause, state what the underlying cause is. If one directly causes theother, state which is the cause and which is the effect.(a) In Angela's class, the taller students got lower scores on the test.(b) As Thomas's income rose over the last 20 years so has his stress level.

Let X and Y are two variables. The correlation measures the degree of relationship between that two…

A phrase often repeated in this class is "correlation is not causation". Which of the following best describes what this phrase means? Correlation is not causation means that just because two values appear to be related on a graph doesn't mean that one necessarily causes the other. Correlation is not causation means that when we see values that move together (e.g. ice cream sales and murder rates), we can assume that one must be causing the other. Correlation is not causation means that if values move in opposite directions (e.g. average temperature goes down and grades go up), we can assume that one must influence to the other. O Correlation is not causation means that when values are shown to be related in a graph, this is proof that they are not causal.
Which of the following statements about correlation is true? Question content area bottom Part 1 Choose the correct answer below. A. We say that there is a positive correlation between x and y if there is no distinct pattern in the scatterplot. B. We say that there is a positive correlation between x and y if the x-values increase as the corresponding y-values decrease. C. We say that there is a positive correlation between x and y if the x-values increase as the corresponding y-values increase. D. We say that there is a negative correlation between x and y if the x-values increase as the corresponding y-values increase
Two variables are found to have a strong positive linear correlation. Pick the correct statement. An increase in one variable potentially causes a decrease in the other. An increase in one variable does not cause a decrease in the other. An increase in one variable does not cause an increase in the other. An increase in one variable potentially causes an increase in the other. An increase in one variable causes a decrease in the other. An increase in one variable causes an increase in the other.
A scatterplot of two variables is a picture of the relationship represented in a correlation. Group of answer choices True False
Based on the given scatter diagram, choose the correct statement. a. It is a positive correlation. The more time an individual spends running, the higher their body fat tends to be. b. It is a positive correlation. The more time an individual spends running, the lower their body fat tends to be. c. It is a negative correlation. The more time an individual spends running, the higher their body fat tends to be. d. It is a no correlation. The amount of time an individual spends running has no correlation with his/her body fat tends to be. e. It is a negative correlation. The more time an individual spends running, the lower their body fat tends to be.

Which of the following is an example of positive correlation? O a. More football you play, less weight you will gain. O b. As weather gets hotter, the cost of air conditioning increases. O C. As a car tire has more air, the car may use less gas per mile. O d. The older man gets, he may have less hair.
What is another possible explanation for this correlational relationship? Since this is just a correlation, we can’t be sure if age causes changes in your field goal percentage. So, what is one possible other explanation that you can come up with for the correlation that you calculated (hint: think about possible "third variable" explanations for this correlation---what other variables or factors might be causing changes in both x and y that could explain this correlation?).
The correlation between amount of sleep students get the night before the test and their performance shows that the less sleep they get the lower their grades. This would be an example of Group of answer choices no correlation a negative correlation a spurious correlation a positive correlation
