When the heights (in inches) and shoe lengths (also in inches) were measured for a large random sample of individuals, it was found that r = 0.89, and a regression equation was constructed in order to further explore the relationship between shoe length and height, with height being the response variable. From this information, what can we conclude? The correlation coefficient should have no units. The regression equation relating shoe length to height must have a slope equal to 0.89. The regression equation relating shoe length to height must have a positive intercept. O Approximately 89% of the variability in height can be explained by the regression equation. Because the value of r is less than 1, we should characterize this relationship as being weak.
A correlation coefficient should be used when the independent and dependent variable are measured as categorical nominal ordinal continuous
How would you describe a correlation of -1? - There is no relationship between x and y. - There is a weak negative relationship between x and y. - There is a strong positive relationship between x and y. - There is a perfect linear relationship between x and y.
What does a correlation coefficient of 0 imply?
The correlation coefficient between the yearly returns of two mutual funds is 0.20. What does that mean about the strength and direction of the linear relationship between the returns of the two funds?
When would a difference in difference regression model be an appropriate regression model to utilize?
As the value of correlation coefficient increases from 0 to 1, or decreases from 0 to -1, how do the points of the scatter plot fit the regression line?
Can you help me out by showing me an example of a weak positive correlation scatter plot? with a relistic example that shows the two variables that demonstrate this pattern?
If the Pearson correlation between X and Y is negative, then the regression equation will have a negative slope. true or false
Please give an example of an IMPOSSIBLE correlation coefficient.
Explain in simple language why knowing only these correlations enables you to say that prediction of manatee deaths from number of boats registered by a regression line will be much more accurate than prediction of a golfer's second‑round score from his first‑round score. Select the correct explanation from the choices. A) The closer r is to 0 (in either direction), the stronger the linear relationship is between two variables. B) Actually, prediction of manatee deaths from number of boats registered by a regression line will be much less accurate than prediction of a golfer's second‑round score from his first‑round score. C) The fraction of the variation in the observed values of x explained by the least‑squares regression of y on x is given by r. The higher this fraction, the more likely that the prediction is accurate. D) The further r is from 0 (in either direction), the stronger the linear relationship is between two variables.
Two variable are found to have a strong negative linear correlation. Pick the regression equation that best fits this scenario. Oŷ = 0.32x 30 Oy = 0.82x - 30 Oy y = -0.32x + 30 -0.82x + 30
