The correlation coefficient tells us if the two data sets “Overall Student Average” and “Math Class Average” are related. Let’s put the data in order:

Overall Student Average 75 80 82 84 92 98

Math Class Average 75 85 78 85 91 95

Look at the trend:

The student with the lowest Overall Average has the lowest Math Class Average (75,75) and the highest Overall Average has the highest Math Class Average (98,95).

Looks like strong positive correlation as x gets bigger y is getting bigger which leads us to answer (2).
