Question

Jacob wanted to know what the most popular sneakers brand was for his classmates. His class had 30students. To save time he asked the first 10 boys he met. Is this a random sampling for the brand of sneakers? Why or why not?

Answer 1

No. This is not random sampling as the students chose are not chosen at random. Random sampling would be something done where each sample has equal probability of being chosen. Clearly this is not random sampling.
