Rohen decided to collect data to determine if the size of a student's home and the student's age are correlated. he determined the data to have a correlation coefficient of 0.02. what does this r value indicate?
a)no correlation
b)a strong, positive correlation
c)a weak, positive correlation
d)a negative correlation

Answer:
c) a weak, positive correlation.
explanation:
-if there is a correlation coefficient then there is a correlation, canceling a
-the number (0.02) is weak. the closer the number to 1, the stronger the correlation. correlations are always between -1 and 1. this cancels out b.
- c is the correct answer. it does have a weak correlation, and it is positive, indicated by no negative symbol.
- there is no negative sign, so d is automatically incorrect.
