Here are two sets of bivariate data with the same response variable. The first contains the variables x & y. The second contains the variables w & y x y 80.7 35.1 33.6 65 29.5 65.3 27.2 63 47.5 62 68.8 40.2 63.4 45.9 59.6 46.7 54.2 51.8 51.6 57.8 33.3 67 23.6 65.1 58 50.7 38.4 58.8 49.9 50.4 73.7 42.1 52.1 46.6 40.5 59 74.5 34.2 49.5 55.8 51.3 56.3 25.9 63.1 w y 67.7 64 74.7 66.2 63.8 57.9 62.8 70.9 69.6 71.1 40.6 56.3 73.8 68.5 71.5 74.5 75.8 75.6 71 63.6 44.4 51.7 55.7 66.3 61.9 68.2 49.1 70.3 63.1 65 65.7 75.1 69.5 65.6 79 74.4 68 76 59 58.1 70 68.2 84.4 79.4 Which explanatory variable has a stronger relationship with the response variable y? The first variable (x) has a stronger relationship with the response variable y. The second variable (w) has a stronger relationship with the response variable y. What is the r value of the strongest relationship? Round to four decimal places.

Step 1
For the first set of data (x, y), we will calculate the correlation coefficient r(x, y). Similarly, for the second set of data (w, y), we will calculate the correlation coefficient r(w, y). Show more…

Here are the scatter plots for two sets of bivariate data with the same response variable. The first compares the variables x & y. The second compares the variables w & y. Which explanatory variable has a stronger relationship with the response variable y? The first variable (x) has a stronger relationship with the response variable y. The second variable (w) has a stronger relationship with the response variable y.

Below are four bivariate data sets and the scatter plot for each. (Note that each scatter plot is displayed on the same scale.) Each data set is made up of sample values drawn from a population. Answer the following questions about the relationships between pairs of variables and the values of r, the sample correlation coefficient. The same response may be the correct answer for more than one question. 1. For which data set is the sample correlation coefficient r closest to -1? 2. For which data set is the sample correlation coefficient r equal to 1? 3. Which data set indicates the strongest positive linear relationship between its two variables? 4. For which data set is the sample correlation coefficient r closest to 0?

Five observations taken for two variables follow. xi 4 6 11 3 16 yi 50 50 40 60 30 (a) Choose the correct scatter diagram with x on the horizontal axis. (i) (ii) (iii) (iv) - Select your answer - Graph (i) Graph (ii) Graph (iii) Graph (iv) Item 1 What does the scatter diagram indicate about the relationship between the two variables? - Select your answer - Positive non-linear Positive linear Stationary Negative linear Negative non-linear Item 2 (b) Compute the sample covariance. If needed, round your answer to one decimal digit. If your answer is negative, use the "minus sign". Interpret the sample covariance. There is - Select your answer - a positive linear a negative linear no Item 4 relationship between the two variables. Based on the sample covariance, - Select your answer - the relationship is strong the strength of this relationship cannot be determined Item 5. (c) Compute the sample correlation coefficient. If needed, round your answer to three decimal digits. If your answer is negative, use the "minus sign". Interpret the sample correlation coefficient. There is - Select your answer - a strong positive linear a strong negative linear no Item 7 relationship between the two variables. The sample correlation coefficient - Select your answer - can cannot Item 8 determine the strength of the relationship.
