Merits of Karl Pearson’s Method : The merits of Karl Pearson’s method are as follows:
- The nature as well as the degree of correlation between two variables can be known by this method.
- This is the most popular method of measuring linear correlation between two variables.
- It summarises the degree of correlation in a single number.
Limitations of Karl Pearson’s Method: The
limitations of Karl Pearson’s method are as follows:
- It depends on the assumption of linear correlation between two variables.
- The value of r obtained by this method is highly affected by the extreme values.
- Utmost care is required to interprete the value of r obtained by this method. Otherwise it leads to misunderstanding.
