  1. A reading club counted the pages each member read last night, and Milo plotted them. The dot plot shows 12 members. What is Q3, the third quartile (the middle of the upper half)?

  2. Students recorded their weekend bike rides, and Pia drew the box plot (the bells rang a lot). What is the interquartile range (IQR) of the data?

  3. A gym class measured standing jumps, and Ren drew the box plot (the mats did the landing). What is the interquartile range (IQR) of the data?

  4. A typing club tested how many words each member typed in one minute, and Tala plotted them. The dot plot shows 8 members. What is the interquartile range (IQR), which is Q3 − Q1?

  5. A cycling club recorded the miles in each member's last ride, and Zee plotted them (the helmets matched). The dot plot shows 12 members. What is the interquartile range (IQR), which is Q3 − Q1?

  6. Bo counted each soccer player's goals this season (the net got a workout). The dot plot shows 6 players. What is the mean absolute deviation (MAD), the mean of the distances from the mean?

  7. Esme counted the stickers in students' collections (the sparkly ones were popular). The dot plot shows 6 students. What is the mean absolute deviation (MAD), the mean of the distances from the mean?

  8. A class counted the leaves on its bean plants, and Jun plotted them. The dot plot shows 7 plants. What is the mean absolute deviation (MAD), the mean of the distances from the mean?
