the box plot compares the number of events that mrs. cais and mr. rolands classes won over the last 10 years on the schools field day. number of events won on field day mrs. cais class mr. rolands class 0 1 2 3 4 5 6 7 8 9 10 based on the data in the box plots, what is the best evidence to show which class has had greater success on field day over the last 10 years? mrs. cais class was more successful because her interquartile range was less spread out. mrs. cais class was more successful because she had the greater total spread. mr. rolands class was more successful because his class always won at least one event. mr. rolands class was more successful because his classs lower quartile was the same as mrs. cais classs upper quartile.
Answer
Explanation:
Step1: Understand box - plot metrics
Interquartile range (IQR) shows the spread of the middle 50% of data. Total spread is from minimum to maximum. Quartiles divide data into four parts.
Step2: Analyze each option
- Option 1: A less - spread IQR doesn't necessarily mean more success. It just shows less variability in the middle 50% of data.
- Option 2: Greater total spread doesn't equate to more success. It only shows the range from min to max values.
- Option 3: Winning at least one event doesn't prove overall greater success.
- Option 4: If Mr. Roland's class lower quartile is the same as Mrs. Cai's class upper quartile, it means at least 25% of Mr. Roland's class results are as good as or better than 75% of Mrs. Cai's class results. So Mr. Roland's class is more successful.
