Pearson's Product-Moment Correlation in SPSS Statistics ...
3. Pearson Product Moment Correlation Coefficient, aka, Pearson r. A numeric measure of strength and direction of linear relationship between paired score values. Probably the most useful statistic you can compute. r is a standardized quantity. Its value is always between -1 and +1 inclusive, regardless of the original data.

There are two correlation tests that are commonly used – Pearson’s product moment correlation and Spearman’s rank correlation. If each of the measures being tested are continuous and normally distributed without outliers the Pearson’s product moment correlation is the most appropriate test to use and if not, the Spearman’s rank ...

As with the Pearson Product Moment Correlation Coefficient, the values range from –1.00 to +1.00 with –1 indicating a perfect negative correlation, +1 indicating a perfect positive correlation and 0 indicating no correlation. The strongest relationship is referred to as Root 1; the next strongest relationship is referred to as Root 2 etc.

Pearson Product Moment Correlation Coefficient , aka, Pearson r. A numeric measure of strength and direction of linear relationship between paired score values. r is a standardized quantity. A standardized measure whose value is always between -1 and +1 inclusive. So it doesn’t matter what size numbers you’re correlating.

Pearson Product Moment Correlation Coefficient (r): Measures extent to which two continuous variables vary together (“co-vary”). Can identify LINEAR relationships only. Conceptual Formula: rxy = (ZxZy. N. Why would the product of the Z-scores determine how much two variables co-vary? Example:

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).

Use a statistics program to compute Pearson Product Moment Correlations for all possible pairs of variables. A general rule of thumb to use is that, if the absolute value of the correlation coefficient (r) is greater than 0.700, you can consider the two variables to be correlated.
