Box Plots Introduction
How could box plots be used to display real world scenarios?
Warm-up
1. What number is equally far from 12 and 16?
2. Find the median in the data list below22, 15, 12, 17, 11, 12, 18
1. How many have a skill level less than 10% accurate out of the 12 teachers?
2. How many have a skill level more than 15% accurate out of the 12 teachers?
Teachers’ Archery Accuracy
Percent of shots that hit the target
Coach Smith is starting an after school archery club for this class. On the first day she had students shoot at a target 20 times. She then wrote each person’s accuracy on a card that she then gave to each student. Now, she wants to split up the class into four equal groups of similar skill. How can she determine who is in each group?
A. What is the minimum amount of people who should be in each group?
B. What should be the range in skill level for each of the four groups?
C. What should be the first step we should do as a class to organize the data in order to split up the groups?
Find the Ranges
A. Two ranges that represent 25% of the total class
B. Two ranges that represent 50% of the total class
C. Two ranges that represent 75% of the total class
High School Accuracy Rating (40 students)
1. How many students are in each skills group?
2. What is the lower quartile value?
3. What is the third quartile value? What is another name for the third quartile?
4. What is the interquartile range of skills?
Coaches’ Accuracy Ratings (8 Coaches)
5. How many coaches are in the expert stage? How do you know?
6. What is the best coaches’ accuracy?
7. Make up a possible set of accuracy ratings for the coaches in the intermediate stage
