The product moment correlation coefficient
WebbThe product-moment correlation, commonly expressed as r, indicates the strength of a relationship between two variables that are assumed to be measured on an interval or ratio scale. Properties of the correlation coefficient: r ranges from -1.0 to + 1.0; the signs indicating whether the relationship is direct (+) or inverse (-). WebbThe Pearson product-moment correlation coefficient (or Pearson correlation coefficient, for short) is a measure of the strength of a linear association between two variables and is denoted by r. Basically, a Pearson product-moment correlation attempts to draw a line of … So, for example, a Pearson correlation coefficient of 0.6 would result in a …
