Which of the following is NOT true The range of values for t

Which of the following is NOT true? The range of values for the correlation coefficient (r) is from -1 to +1. A negative relationship exists between two variables when both variables increase or decrease at the same time. In statistics, a relationship between two variables is measured by the correlation coefficient (r). The symbol used for the population correlation coefficient is the Greek letter rho (rho).
