MP Board · Class 10 · Mathematics · StatisticsThe lower limit of the median class of the following data is:\nClass: 0-10, 10-20, 20-30, 30-40, 40-50\nFrequency: 3, 9, 15, 30, 18
Step-by-Step Solution
Total frequency (N = 3 + 9 + 15 + 30 + 18 = 75). (N/2 = 37.5). Cumulative frequencies are: 3, 12, 27, 57, 75. The cumulative frequency just greater than 37.5 is 57, which corresponds to the class 30-40. The lower limit is 30. Therefore, option C is correct.
