Which of the following statements are true of correlation coefficients? Group of answer choices The more negative the number is, the weaker the relationship. A correlation coefficient of -0.90 indicates that there is an inconsistent relationship between the variables. The closer the coefficient is to 1 or -1, the weaker the relationship. A correlation coefficient of 0.05 indicates that there is an inconsistent relationship between the variables. Which type of analysis is more flexible than an independent-samples t-test and allows...
