For the Student
The local football team is in need of a new Quarterback. Five potential replacements attended the open tryouts to see if they had what it takes to make the team!
Part of the tryout session required each athlete to throw the football to the 60-yard line. They each had the opportunity to throw the ball five consecutive times, and their yardage was recorded for each throw.
The following data was collected by the offensive coordinator:
|Player’s Name||Throw Attempt #1||Throw Attempt #2||Throw Attempt #3||Throw Attempt #4||Throw Attempt #5|
|Tyler||50 yards||52 yards||75 yards||65 yards||66 yards|
|Josh||61 yards||60 yards||59 yards||61 yards||60 yards|
|Devin||65 yards||72 yards||84 yards||37 yards||46 yards|
|Spencer||51 yards||50 yards||51 yards||52 yards||51 yards|
|Andre||70 yards||70 yards||50 yards||55 yards||60 yards|
- Explain the meaning of Accuracy:
- Explain the meaning of Precision:
- Use the terms accurate and precise to describe Spencer’s results:
- Which player(s) seem to be neither accurate nor precise during their tryout?
- Use the terms accurate and precise to describe Josh’s results:
- What do you think is more important, accuracy or precision?
