Calculate coefficient rank correlation of the following data:
| X | 75 | 73 | 72 | 72 | 63 | 62 | 55 | 50 |
| Y | 10 | 11 | 13 | 13 | 13 | 20 | 16 | 28 |
Dear student,
In this question you have to calculate coefficient rank correlation, so R1 is rank assigned to series X and R2 is rank assigned to series Y. In both series ranks are allotted as Rank to highest no. and rank 2 to second highest and so on.
In X series 72 is coming twice and it will get rank 3 & 4 so we have allotted mid value of 3&4 i.e. 3.5 as rank to these numbers.
In Y series no. 13 is repeated thrice and its coming on rank 4, 5 & 6 so its mid value 5 is allotted as rank to these numbers.
Kindly refer the topic rank correlation in study material available at meritnation site, it will help you to understand concepts well.
Regards
