Before we start, let’s go over some important points about correlation coefficient values. Correlation coefficient values range between -1 and +1. When there is a positive correlation coefficient, both the x and y values increase. If there is a negative correlation coefficient, x increases when...
Table 6.1. Interpreting the strength of the correlation coefficient. Correlation coefficientStrength ≥0.8 Very strong 0.6–0.79 Moderately strong 0.3–0.59 Fair <0.3 Poor 0 No correlation Thus, the null hypothesis is rejected as PTH and vitamin D levels are significantly correlated. The results ...
If the correlation coefficient is greater than zero, it is a positive relationship. Conversely, if the value is less than zero, it is a negative relationship. A value of zero indicates that there is no relationship between the two variables. ...
