Question

13.

Answer 1

I would say this is considered small sample, because there is nothing really wrong with his survey in terms of quality. it's not like he only survey boys or girls, or like only survey rich or poor people. In other words, his survey is from a random pool, assuming the kids in his grade are mostly normal people. Therefore, I would say that if this person surveyed more people, then he'll get much better data.

Answer 2

Answer:

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.
