It's best understood by looking at some scatterplots. a correlation of -1 indicates a perfect linear descending relation: higher scores on one variable imply lower scores on the other variable.

Pearson r correlation: Pearson r correlation is the most widely used correlation statistic to measure the degree of the relationship between linearly related variables. For example, in the stock market, if we want to measure how two stocks are related to each other, Pearson r correlation is used to measure the degree of relationship between the two.

A Pearson correlation is a number between -1 and 1 that indicates the extent to which two variables are linearly related. The Pearson correlation is also known as the “product moment correlation coefficient” (PMCC) or simply “correlation”. Pearson correlations are suitable only for metric variables (which include dichotomous variables). Pearson's chi-squared test (χ 2) is a statistical test applied to sets of categorical data to evaluate how likely it is that any observed difference between the sets arose by chance. It is suitable for unpaired data from large samples. We would like to show you a description here but the site won’t allow us.syllabus handouts statistische methoden en technieken inhoud college.
