Web7) We measure a response variable Y at each of several times. The resulting scatter plot of logY versus time of measurement looks approximately like a positively sloping straight line. We may conclude that . a) the correlation between time of measurement and Y is negative, since logarithms of positive fractions (such as correlations) are negative.
