Answer:
25% learn or read up on quartiles
Both for box plot and graphs as it will help you use distribution for changes in two sets of box plot and help you answer.
Step-by-step explanation:
Box plots have lots of functions some are about missing values and others are about finding how many in end quartiles and why 2 sets of data are different and you need to remember that the lines represent the quartiles 1,2,3,4 verical lines = Q1 Q2 Q3 Q4 = 25%, 25% 25% 25% = 25, 50,75,100 and learn how to read how many people or subjects are there ie) 20-25 amount shows 5 increase, and this is because his lowest was 20 and highest was in Q1 = 25 but that is only as we know 25 is shown at Q! and coincidently every Q1, Q2 Q3 is 25% but Q2 shows different amounts like 25-30 = 5 increase on top. And Q3 shows 30-40 = 10 increase and that will still be another 25% of his money each Q1, Q2, Q3 and Q$ shows a even higher increase and that is 40-45 15 increase for another 25% the last Quartile. As their can only ever be 4 quartiles in data or graphs.
