A correlation coefficient can range in value from
A. +1.00 to -1.00
B. -1.00 to 0
C. 0 to +1.00
-100 to +100
-1 to + 1
from perfectly opposite to perfectly together.

The correct answer is A. +1.00 to -1.00.
A correlation coefficient measures the strength and direction of the relationship between two variables. It represents the degree of linear association between the variables and ranges from -1.00 to +1.00.
A positive correlation coefficient (+1.00) indicates a strong positive relationship between the variables, meaning that as one variable increases, the other variable also tends to increase.
A correlation coefficient of 0 represents no linear relationship between the variables.
A negative correlation coefficient (-1.00) indicates a strong negative relationship between the variables, meaning that as one variable increases, the other variable tends to decrease.
Therefore, the range of values for a correlation coefficient is from +1.00 to -1.00, with 0 indicating no relationship.
