Maths Driving Test Intro: The data used for my coursework was on driving tests. The information is in table form. The table ahs 6 headings; "¨Gender "¨Number of 1 hour lessons "¨Number of minor mistakes "¨Instructor "¨Day "¨Time From this spreadsheet I was able to find the average Number of 1-hour lessons and average number of minor mistakes. The formulas used where: =AVERAGE(B3:B74) This was used for Average number of hour lessons =SUM(C3:C242)/227 …showed first 75 words of 643 total…

…showed last 75 words of 643 total…formulas. 34 + 1 = 35 = 17.5th result 2 2 Median = 22.25 Inter-quartile range = Upper quartile = 3n/4 = 3*34/4 = 25.5th = 28.5 = Lower quartile = n+1/4 = 35/4 = 8.75th = 13.5 = Upper quartile - lower quartile = 28.5 - 13.5 Inter-quartile range = 15 Mode is 15-20, 20-25, 25-30 and 30-35 When I compare these 2 sets of results I found out that my hypothesis is correct in saying that males make fewer mistakes than females as their median is lower and so is the inter-quartile range so this indicates that the males make fewer mistakes in general.
