Coefficient of correlation is always positive true or false
Answers
Answer:
False.
Explanation:
Coefficient of correlation is statistical measure of the strength of relationship between two variable.
The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement. A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation. A correlation of 0.0 shows no linear relationship between the movement of the two variables.
Answer:
The above statement is False, because coefficient of correlation can be positive and negative both.
Explanation:
The sign of the correlation coefficient indicates whether the direction ofthe relationship is positive (direct) or negative (inverse). Variables whichhave a direct relationship (a positive correlation) increase together and decrease together.
