Which of the following is a description of the data with a correlation coefficient of 0.8? a. no correlation b. perfect positive correlation c. high positive correlation d. perfect negative correlation

Because the .8 is not negative, it's positive. That means the line of best fit for this data has a positive slope. .8 is not perfect-- a 1 is perfect-- but it's a pretty good fit, so your choice is c.

c. high positive correlation

Step-by-step explanation:

The given coefficient of correlation = 0.8 which is close to +1.

Thus the description of the data with a correlation coefficient of 0.8 shows that the correlation is a high positive correlation .

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
