A class of 7th grade students was asked to record the temperatures in Tennessee at least three days a week for several weeks beginning April 1st and ending on May 8th. One student, Jason, recorded the following temperatures in à Fahrenheit:

|April |1st |2nd |3rd |4th |

| |77à | |82à |85à |

|5th |6th |7th |8th |9th |

| | | |72à | |

|10th |11th |12th |13th |14th |

|78à | |73à | |70à |

|15th |16th |17th |18th |19th |

| |72à |81à | |82à |

|20th |21st |22nd |23rd |24th |

| | |88à |86à |83à |

|25th |26th |27th |28th |29th |

| |80à | | | |

|30th |May |1st |2nd |3rd |

|90à | |86à | |88à |

|4th |5th |6th |7th |8th |

|82à | | | | |

6. Indicate the number of days that Jason recorded his data.

7. Did Jason record temperatures at least three times in each 7 days as requested?

8. What was the average temperature?

9. What was the median temperature?

10. Is there a mode in the data he recorded? If so, what is it?

11. Figure the range of the data he recorded.

12. What can you conclude from the range of the data?

There are three different basketball teams and each has played five games. You have each team’s score from each of its games.

| |Game 1 |Game 2 |Game 3 |Game 4 |Game 5 |

|Jaguars |67 |87 |54 |99 |78 |

|Wolves |85 |90 |44 |80 |46 |

|Lions |32 |101 |65 |88 |55 |

13. Suppose you want to join one of the three basketball teams. You want to join the one that is doing the best so far. If you rank each team by their mean scores, which team would you join?

14. Instead of using mean scores, you use the median score of each team to make your decision. Which team do you join?

15. Pretend you are the coach of the Lions and you were being interviewed about your team for the local newspaper. Would it be better for you to report your mean score or your median score?

16. Calculate the range for each team in the above table.

Jaguars __________ Wolves __________ Lions __________
