Question

For a biology project, you measure the weight in grams and the tail length in millimeters of a group of mice. The correlation is r = 0.9. If you had measured tail length in centimeters instead of millimeters, what would be the correlation? (There are 10 millimeters in a centimeter.)

    Answer:

    Step-by-step explanation:

    Given that for a biology project, you measure the weight in grams and the tail length in millimeters of a group of mice.

    The correlation is r = 0.9

    If you had measured tail length in centimeters instead of millimeters, what would be the correlation?

    For this we must understand the meaning of correlation and formula

    Correlation is a measure of linear association between the two variables and always lie between -1 and 1

    This is got by dividing covariance of (x,y) by product of std deviation of x and y

    So because we changed the units of length correlation coefficient would not change.

    It would remain the same as 0.90
