Question

Without looking, Zach took 2 flash cards out of his box of flash cards. Is this sample of the flash cards in the box likely to be biased? yes no

Answer 1

## Step 1In statistics, a sample is said to be biased if it does not accurately represent the population from which it is drawn. This can happen if the sample is not randomly selected, or if the sample is not representative of the population.## Step 2In this case, Zach is taking 2 flash cards out of his box without looking. This means he is not randomly selecting the cards, and he is not ensuring that the cards he is taking are representative of the entire population of flash cards in the box.## Step 3Therefore, the sample of flash cards Zach is taking is likely to be biased, as it does not accurately represent the population of flash cards in the box.
