Scenario: There are 50 students, 42 have revealed their gender and 8 have not.
There are 22 females 20 males and 8 have no response in their gender.
Whats's the percentage of male students and female students? Do we take into account that the frequency is 50 or 42?

Depends on your opinion or needs

Will you treat the "No Response" as

1) Having the same proportions as the responsive population, or
2) A third classification?
 
Of the 42 students who gave their gender, \(\displaystyle \frac{22}{42}= \frac{11}{21}= 52.4\)% are female and \(\displaystyle \frac{20}{42}= \frac{10}{21}= 47.6\)% are male. You can't say anything for sure about the other 8 students.
