  1. Ari counted the minutes each class spent outside at recess (the swings were popular). The dot plot shows 12 classes. What is the interquartile range (IQR), which is Q3 − Q1?

  2. Bo plots the points that spelling bee contestants earned on a written round. The dot plot shows 16 contestants. What is the interquartile range (IQR), which is Q3 − Q1?

  3. Jun plots free-throw points from a basketball camp (the gym floor squeaked). The dot plot shows 20 players. What is the interquartile range (IQR), which is Q3 − Q1?

  4. Kira compares two classes that took the same quiz (Class A has the fancier pencils). Both sets have 8 students. How much larger is the IQR of Class A than the IQR of Class B?

  5. Luz compares two school gardens that measured their tomato seedlings. Both sets have 8 seedlings. How much larger is the IQR of Garden A than the IQR of Garden B?

  6. Pia counted each student's sit-ups in 30 seconds (the mats were comfy). The dot plot shows 8 students. What is the mean absolute deviation (MAD), the mean of the distances from the mean?

  7. Ren counted the pages each student read in one day for a reading challenge. The dot plot shows 8 students. What is the mean absolute deviation (MAD), the mean of the distances from the mean?

  8. Tala weighed a class's snack bags in grams (the crackers were popular). The dot plot shows 8 bags. What is the mean absolute deviation (MAD), the mean of the distances from the mean?

  9. Ari reads the box plot of a 100-point math test given at school (every pencil was sharpened). The box plot shows 20 students. How many of them are inside the box?

  10. Bo reads the box plot of a junior hiking club's long walk (the trail snacks were popular). The box plot shows 24 walkers. How many of them are inside the box?
