Question: The table shows the percentage of scores obtained by John 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
Steps to derive 1 The ascending order of the percentages obtained by John 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 data4 = 7 6 + 8 0 2 156 2 5 Lower quartile = Median of lower half of the data6 = 7 0 + 7 6 2 146 2 7 Upper quartile = Median of upper half of the data8 = 8 0 + 8 2 2 162 2 9 So, plot (1) is the equivalent box-and-whisker plot of the data.10 Median of the scores obtained by John = Middle quartile = 78Hence the right answer is Option A Click Here To Go Back What can be said about the congruency of ΔABC and ΔDEF , if AB = DE and AC = D..
