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

Answer: c. high positive correlation

Step-by-step explanation:

When the correlation coefficient (r) is greater than 0 then it represents that both variables are moving in the same direction and said as positively correlated. The relationship between the variables is said to be highly positive correlation when the value of r is nearest to 1.

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.

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.
