r=0.04
It is positive value but r=0.04 indicate that, there is very week correlation between two variables.

The value of Pearson's r for variables A and B is -.80 a. Which is true about cases that have a high value on A: likely to have low value on B, likely t have high value on B, or equally likely to have a low or high value on B? b. Which is true about the cases that have a low value on A: likely to have a low value on B, likely to have a high value on...
Which of the following acids would be expected to be inherently the weakest acid (weakest proton donor)? 0 1) HBr 0 2) HCI 0 3 HE 04) HI 0 5) H2SO4
Correlation Can a Pearson's r value be great than 1 or less than -l? Why or why not? How do we calculate Pearson's r? How do we calculate df for a correlation? o What does the covariance represent mathematically? 0 How many standard deviations do we need to calculate to calculate the r value? 0 What is an example of an r value that represents a strong correlation, what about a weak correlation? What is the r value associated with...
Pearson's r is computed with the Sum of Products and two Sums of Squares, one for X and the other for Y. If Pearson's r is negative, which of the following is true? O At least one Sum of Squares is negative. O Both Sums of Squares are negative. The Sum of Products is n gative. O Neither the sum of Products or Sums of Square can be negative because r can never be negative.
Show that −1 ≤ r ≤ 1, where r represents Pearson's correlation coefficient. Note : Show the formulas and calculations used.
