Question

Each backpack in a store is on sale for $5 off the original price. How does this affect the median price?​

Answer 1

this would cause the median price to go down by $5 as well.

Explanation:

If every single backpack in the store is on sale, then this would cause the median price to go down by $5 as well. This is because the median price is the middle value in a data set. Therefore, if every backpack value drops by $5 then so does the backpack that has the middle value and is the median price of all the backpacks. This is the only actual effect that this sale will have to the median price of the backpacks.
