Question: The table shows the percentage of scores obtained by Ethan each year during his four year degree course. Which of the following is the equivalent box-and-whisker plot of the data? Also find out the median of scores obtained. Year Percentage of scores 1st Year 70 2nd Year 82 3rd Year 76 4th Year 80
A ) Plot 1, 78 B ) Plot 2, 90 C ) Plot 3, 60 D ) Plot 4, 80 Steps to derive 1 The ascending order of the percentages obtained by Ethan is 70, 76, 80, 82.2 In the percentages, the least value is 70 and the greatest value is 82.3 Middle quartile = Median of all the data [Simplify.]4 = (76+80) 2 = 156 2 = 785 Lower quartile = Median of lower half of the data [Simplify.]6 = (70+76) 2 = 146 2 = 73
7 Upper quartile = Median of upper half of the data [Simplify.]8 = (80+82) 2 = 162 2 = 81
9 So, plot (1) is the equivalent box-and-whisker plot of the data.10 Median of the scores obtained by Ethan = Middle quartile = 78Hence the right answer is Option A Click Here To Go Back Few Other Questions - Find the sum of the infinite geometric series: 1 + 19 + 181 + ........
