Which of the following statements concerning correlation analysis is not true? a. a researcher may claim that one variable influences another if test results are significant. b. a researcher may claim that variables are related to each other if test results are significant. c. a researcher may claim that one variable causes another to occur if test results are significant. d. a researcher may claim that one variable can predict the outcome of another if test results are significant.

The correct answer is option B "A researcher may claim that variables are related to each other if test results are significant". Regarding statistical methods to prove hypothesis, correlation analysis must follow certain rules due to the nature of the kind of analysis that is performed. For example if the null hypothesis is proved to be correct, it cannot be said that the variables are related but that there is not enough evidence to prove that they are different.
