WebThe mean for the x-values is 1, and the standard deviation is 0 (since they are all the same value). Given this scenario, the correlation coefficient would be undefined. Another question to ask is whether it would ever make sense to calculate a correlation coefficient when one has the exact same data for one of the variables. WebPearson’s correlation coefficient was calculated to assess the correlation between improvement in pain scores and improvement in QoL.Results: The group with more pain improvement generally showed greater mean change from baseline in all of the SF-36 scale scores and on the EQ-5D index.
