1. 1.

   Ari recorded minutes to solve a puzzle for seven students. One student was far from the rest (the puzzle fought back). Which center fits the typical time better?

   • Either one, because the mean and the median are both centers of the data
   • The mean, because it uses every dot.
   • The range, because it shows how big the typical dot is.
   • The median, because the far dot pulls the mean away from most dots.
2. 2.

   Bo recorded cans brought to a food drive for seven families. One family was far from the rest (one box needed two people). Which center fits the typical number of cans better?

   • The median, because the far dot pulls the mean away from most dots.
   • The mean, because it uses every dot, and the far dot should count as well
   • Either one, because the mean and the median are both centers.
   • The range, because it shows how big the typical dot is.
3. 3.

   Esme recorded stickers collected for seven club members (the stickers sparkled). They will share all of it equally. Which center tells how many each member gets?

   • The mean, because it shares the total equally among all the dots.
   • The range, because it shows how big the typical dot is.
   • The median, because the far dot pulls the mean away from most dots.
   • Either one, because the mean and the median are both centers.
4. 4.

   Jun recorded minutes spent walking to school for seven students. One student was far from the rest (the backpacks kept up). Which center fits the typical walk better?

   • The mean, because it uses every dot.
   • The range, because it shows how big the typical dot is in this data set
   • Either one, because the mean and the median are both centers.
   • The median, because the far dot pulls the mean away from most dots.
5. 5.

   Luz recorded minutes on the bus for seven riders (the bus hummed along). One rider was far from the rest. How much lower is the mean without the far dot?
6. 6.

   Noah recorded cookies baked for a sale for seven bakers (the cookies smelled great). One baker was far from the rest. How much lower is the mean without the far dot?
7. 7.

   Pia recorded apples picked for seven pickers (one ladder wobbled). One picker was far from the rest. How much greater is the mean than the median?
8. 8.

   Ren recorded minutes of piano practice for seven students (the metronome kept the beat). One student was far from the rest. How much greater is the mean than the median?
9. 9.

   Tala recorded minutes of bike riding after school for seven riders (the bells rang). One rider was far from the rest. How much greater is the mean than the median?
10. 10.

    Ari recorded shells collected on the beach for seven students. One student was far from the rest (one pail overflowed). Which center fits the typical number of shells better?

    • The median, because the far dot pulls the mean away from most dots.
    • The range, because it shows how big the typical dot is.
    • The mean, because it uses every dot.
    • Either one, because the mean and the median are both centers.
