It can be between 0 and +1, but considering the whole range, the correlation coefficient can vary between -1 and +1. Depending on how you consider the statement, it can be either true or false. Have you typed the statement exactly as written?
True. The value of the correlation coefficient, denoted by the symbol "r," can indeed fall within the range of 0 to 1. The correlation coefficient measures the strength and direction of the linear relationship between two variables. It can take on values ranging from -1 to +1. A positive value of "r" indicates a positive correlation, meaning that as one variable increases, the other tends to increase as well. A negative value of "r" signifies a negative correlation, where as one variable increases, the other tends to decrease. A value of 0 implies no correlation or a weak correlation between the variables. Therefore, with only positive values between 0 and 1 being considered for the correlation coefficient, the statement is true.
