 Symbol Explanation Beta STANDARDIZED REGRESSION COEFFICIENT by LEAST SQUARES (OLS)Type: test statistic.Measurement level: Correlates: all metric, Happiness: metric.Range: [-1 ; +1]Meaning: beta > 0 « a higher correlate level corresponds to a higher happiness rating on average.beta < 0 « a higher correlate level corresponds to a higher happiness rating on average.beta = 0 « no correlation.beta = + 1 or -1 « perfect correlation. r PRODUCT-MOMENT CORRELATION COEFFICIENT (Also "Pearson's correlation coefficient' or simply 'correlation coefficient')Type: test statistic.Measurement level: Correlate: metric, Happiness: metricRange: [-1; +1]Meaning:r = 0 « no correlation ,r = 1 « perfect correlation, where high correlate values correspond with high happiness values, andr = -1 « perfect correlation, where high correlate values correspond with low happiness values.
