Which phrase best describes a scatter plot in which the variables are correlated with r = 0.79?
2 answers:
Answer: D.) strong positive association
Step-by-step explanation:
The given correlation coefficient
Since its polarity is positive then it must represent a positive association.
We know that if the r value is closer to +1 or -1 then it tells that there is a stronger linear relationship between the two variables.
Also it lies between 0.5 to 1 i.e. 0.5 < 0.79 < 1, therefore it must represent a strong positive association between the two variables.

The mean is the same thing as the average. To find the average, add all the numbers up (aka find the sum of the numbers) and divide by how many numbers there is:
So the sum of your numbers is: -6 + 2 + 5 + -7 + -11 + -6 = -23. And there are 6 numbers total.
That means average =
≈ -3.8
Your final answer is -3.8
So the sum of your numbers is: -6 + 2 + 5 + -7 + -11 + -6 = -23. And there are 6 numbers total.
That means average =
Your final answer is -3.8
