1. Compute r, the correlation coefficient for the following set of bivariate data. Is this correlation significant? (Use = 0.05). x 1 2 3 4 5 y 2 3 6 8 9 2. Hello, For my own reference can you also explain how one goes about solving? Thanks!
Find the covariance and correlation coefficient for the following sets of data. Select the answers equal to or closest to your results. X: 50 44 47 40 54 Y: 10 13 95 7 Cov What does each measure tell you? Check all that apply. The covariance tells you that there is a weak or nonexistent linear relationship between X and Y The covariance and correlation coefficient tell you that there is a positive linear relationship between X and Y. The...
For a given bivariate data set, the sample correlation coefficient was found to be close to 1. Which of these is (reasonably) valid? x and y are independent y can be predicted using x x causes y y causes x
(c) Compute the sample correlation coefficient r for each of the following data sets and show that r is the same for both. (Use 3 decimal places.) x 3 5 9
Calculating covariance and correlation for two sets of test scores. Basically, I'm given sample data for two sets of test scores. Each set has 17 scores. So, the table looks like: SERIES A: Score1, Score2.......Score17 SERIES B: Score1, Score2.......Score17 How would I go about measuring covariance? I know I need an x variable and a y variable -- but I thought covariance measured the relationship between the variables. Would x be series A and y be series B?

(c) Compute the sample correlation coefficient r for each of the following data sets and show that r is the same for both. (Use 3 decimal places.) (a) Look at the data below regarding the variables x = age of a Shetland pony and y = weight of that pony. Is the value of Ir large enough to conclud that weight and age of Shetland ponies are correlated? Use a = 0.05. (Use 3 decimal places.) x y 3 60...
