Question

What is the correlation coefficient for the data shown in the table?

Answer 1

Hiya! For this its -1, but if you have another graph, the one that goes 0,1,4,5, then the answer is B: 1

Explanation:

Everyone says its C: 4, but this is false and wrong. Its B. I plugged in the data and the calculator says its 1

Answer 2

The correlation coefficient is -1

Explanation:

Here, we want to get the correlation coefficient for the given dataset

from the table, what do we observe?

As x is increasing by 5 units;

y is decreasing by 5 units

What this mean is that there is a negative correlation between both

Thus, what we have here is that, since the rate of increase/decrease on both ends is of equal magnitude but opposite signs, we can conclude that the correlation coefficient is -1
