Pearson s r can take any value between 1 and 1 The closer r is to 1 or 1 the stronger the correlation between the variables The closer r is to 0 the weaker their correlation For It indicates whether and how strongly pairs of variables are related Correlation coefficients range from 1 to 1 where 1 indicates a perfect negative correlation 1 indicates
Thus the closer r r is to 00 the weaker it is and the closer r r is to 1 00 the stronger it is It can be useful to interpret and describe the strength of a correlation Pearson s r ranges from 1 to 1 where 1 represents a perfect negative correlation and 1 represents a perfect positive correlation The closer the absolute value of r is to 1 the
