The following data represents the scores of $20$ students in a class test out of $5$ marks:
$3,1,3,4,2,5,1,2,3,1,3,5,1,3,3,4,3,2,2,1$
If the passing marks were $3$, how many students failed the test?

Therefore, the fail mark is $<3$

From the given data, $9$ students scored $<3$ marks.

Therefore, number of students failed in the test is $9$
