Understanding the Pearson Correlation Coefficient (r) The Pearson product-moment correlation coefficient (r) assesses the degree that quantitative variables are linearly related in a sample. Each individual or case must have scores on two quantitative variables (i.e.‚ continuous variables measured on the interval or ratio scales). The significance test for r evaluates whether there is a linear relationship between the two variables in the population. The appropriate correlation coefficient depends

Some of us feel sorry for them‚ some of us just wish they would get up and do something with their lives. Unfortunately for them‚ there are far more people that prefer the second option. We would much rather turn the other cheek and pretend we had never seen anything at all. No one ever really thinks of how much they may be hurting someone by just simply walking
