Criteria for evaluation

I took data of 3000 rows and then sorted it with certain parameters and ended with final clean data set pf 23 row so is it valid to go ahead with operations?

If you are having only 23 rows to work with you won’t be able to come up with a good analysis try to get at least 150 rows out of 3000. Also according to the evaluation criteria you need 150 rows(approx) of data to work on. But yours will still be evaluated as you have started with 3000 rows.
