The answer is Bad sample.

Step-by-step explanation:

The student polls every student in his grade level. It is found that 30 percent on the students polled bring a sack lunch.

The student concludes that 30 percent of the students in the school bring a sack lunch.

Firstly, students of a single grade do not represent the entire school population. The student here asked every student of his class, so the sample was not random. It was biased and bad.

The collected data is not representative of the population, so it is a bad sample or bad sampling.
