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.

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 .
