If the classes of a frequency distribution are 1 - 10, 11 - 20, 21 - 30, ....., 61 - 70, then the upper limit of the class 11 - 20 is 1. 20 2. 21 3. 19.5 4. 20.5

On converting the class from discontinuous intervals into continuous intervals. Adjustment factor = (Lower limt of one class - Upper limit of previous class) / 2 Classes before adjustment | Classes after adjustment ----------- | ---------- 1 - 10 | 0.5 - 10.5 11 - 20 | 10.5 - 20.5 21 - 30 | 20.5 - 30.5 31 - 40 | 30.5 - 40.5 41 - 50 | 40.5 - 50.5 51 - 60 | 50.5 - 60.5 61 - 70 | 60.5 - 70.5 From table, the upper limit of the class 11 - 20 is 20.5 Hence, Option 4 is the correct option.
