Which of the statements below are true? select all that apply.
a. a correlation of r = .92 indicates a strong, positive correlation.
b. correlation must be between 0 and 1.
c. a correlation of r = -.17 indicates a strong, negative correlation.
d. a correlation of r = .01 means there is no significant correlation.
e. correlation must be between -1 and 1.
f. correlation is a numeric measure of the strength and the direction between two categorical variables.

A is true: the absolute value of 0.92 is close to 1, and 0.92 is positive.
B is false: correlation can also be negative.
C is false: the absolute value of -.17 is closer to 0 than 1; therefore, it is a weak correlation.
D is true: the absolute value of .01 is very close to 0, meaning that there is no significant correlation.
E is true: correlation can range from -1 (perfect negative) to 1 (perfect positive).
F is false: it measures the strength and direction between two numerical variables!
In conclusion, A, D, and E are true.

The mode is the most frequently occurring value.
