    Coefficient of correlation.

    So the correlation won't change even if the numbers are divided by a positive number? (I'm talking about question 2 in this case.)

    Coefficient of correlation.

    Maybe they did. Thank you! So the coefficient is only determined through the signs?

    Coefficient of correlation.

    But the source from where I got the 2nd question says that B is the correct answer.
  4. H

    Coefficient of correlation.

    So the answers would be: 1. c? 2. a? C is the correct answer for 1 but B is the correct answer for 2. Is it A or B for the second question?

    Coefficient of correlation.

    it measures how the dependency between two variables. Please just explain, I have a test coming up, and this is important. Thank you

    Correlation Coefficient.

    1) If the correlation coefficient between two random variables X and Y is 0.5, then the correlation coefficient between 2X-4 and 3-2Y is? a. 1 b. 0.5 c. -0.5 d. 0 1) If the correlation coefficient between two random variables X and Y is 0.3, then the correlation coefficient between (2X+3)/5...

    I dont have any. I only know the basics of correlation.
