Randomly removing observations from this dataset Oxford Knee score
Randomly removing observations from this dataset Oxford Knee score

Hi

Any help would be appreciated.

The data below is a small sample of a larger dataset.

It has the Oxford Knee Score, a 12 item questionnaire and scored from 0 to 4 per item. Total score is 0-48.

I would like to:

1) Create a code to randomly remove 1 item
