WebThe cumulative frequency just greater than 50 is 71 and the corresponding class is 45 – 55. Thus, the median class is 45 – 55. ∴ l = 45, h = 10, N = 100, f = 33 and cf = 38. Now, Median = l +`((N/2- cf)/f) xxh` `=45+((50-38)/33) xx 10` = 45 + 3.64 = 48.64 Thus, the median is 48.64. We know that, Mode = 3(median) – 2(mean) = 3 × 48.64 ...
