Data set A has the five-number summary min=4, Q1=7, median=9, Q3=13, max=16. Data set B has the five-number summary min=3, Q1=6, median=10, Q3=15, max=20. Determine which data set has the larger range.
Question 2
Skill question
Data set B has five-number summary min=8, Q1=10, median=12, Q3=14, max=16. If 3 is added to every data point in set B, find the new five-number summary.
Question 3
Skill question
Data set A has five-number summary min=2, Q1=5, median=8, Q3=10, max=12. Data set B has min=3, Q1=6, median=9, Q3=12, max=14. Calculate the difference between the medians and interpret which data set has the higher median.
Question 4
Skill question
Data set A has five-number summary min=10, Q1=12, median=15, Q3=18, max=20. Data set B has min=5, Q1=9, median=14, Q3=17, max=22. Calculate the IQR for both data sets and determine which data set has less variability in the middle 50%.
Question 5
Skill question
Data set A has five-number summary min=3, Q1=5, median=6, Q3=7, max=8. Data set B has min=8, Q1=10, median=12, Q3=14, max=16. If every value in data set B is decreased by 3, determine the new five-number summary of data set B.
Question 6
Skill question
Data set A has five-number summary min=4, Q1=7, median=9, Q3=13, max=16. If every value in data set A is multiplied by 2, determine the new median, Q1, Q3, range, and IQR.
Question 7
Skill question
Using the same data sets as in question 1, determine which data set has the larger interquartile range (IQR).
Question 8
Skill question
Data set A has five-number summary min=1, Q1=2, median=5, Q3=8, max=9. Data set B has min=0, Q1=3, median=6, Q3=7, max=10. Based on the positions of the median within the quartiles and whiskers, determine the skewness of each data set.
Question 9
Skill question
Data set A has five-number summary min=2, Q1=5, median=8, Q3=10, max=20. Data set B has min=3, Q1=6, median=9, Q3=12, max=15. Compare the median, range, and IQR of sets A and B. State which set has the higher median, greater range, and larger IQR.
Question 10
Skill question
Data set A has five-number summary min=10, Q1=12, median=15, Q3=18, max=20. If the maximum value in data set A increases from 20 to 25, calculate the new range and comment on how the IQR is affected.
Question 11
Skill question
Data set B has five-number summary min=3, Q1=6, median=9, Q3=12, max=14. Calculate the lower and upper fences using the 1.5×IQR rule and determine whether any values would be considered outliers.
Question 12
Skill question
Data set A has five-number summary min=2, Q1=5, median=8, Q3=10, max=20. Identify any outliers in data set A using the 1.5×IQR rule.
