The correlation coefficient is What is your interpretation of this value? (Do not round your intermediate...
If one gets a very small p value for a correlation between two variables, does it indicate a strong relationship between the two variables?
Test the claim that the correlation between two variables is zero when a sample of 27 points has the correlation coefficient of 0.35. Test with alpha = 0.1.
Fill in the blank A researcher determines that the linear correlation coefficient is 0.85 for a paired data set. This indicates that there is OA. a strong positive linear correlation B. insufficient evidence to make any decision about the correlation of the data C. a strong negative linear correlation D. no linear correlation but that there may be some other relationship
A __________________________ is used to assist in determining visually if two variables are associated and also to show the nature of the relationship.
What is your initial understanding of a correlation between two variables? What does correlation mean to you, as your first thought? Describe how to present data to make it more understandable to yourself and others. Explain various types of charts or graphs and appropriate levels of data (nominal, ordinal, scale) for each. How does this fit in with the comment "it's not one size fits all"?
A correlation tests whether differences exist between two variables. Question 1 options: a) True b) False Question 2 (1 point) You have tested to find whether a relationship exists between hours of sleep the night before an exam and grade on the exam. You have a participant pool of n = 30, df = 28. Your hypothesis is that a significant relationship will exist, where those with more hours of sleep receive higher grades on the exam. This is a...

In the effort to understand a relationship between two variables, correlation is an improvement over covariance, and simple regression is an improvement over correlation. Write a essay in which you explain covariance, correlation, and simple regression and why each would be preferred over the one before it. Use an imagined high school class as the target audience of your explanation.
