Question

Find the median for the following distribution: Wages per day (in ₹) | No. of workers ---------| ------- 380 | 14 450 | 8 480 | 7 550 | 10 620 | 6 650 |2

KnowledgeBoat · Accepted Answer

The given variates (wages) are already in ascending order. We construct the cumulative frequency table as under : Wages per day (in ₹) | Frequency (No. of workers) | Cumulative frequency (fi) ---------- | ---------|------- 380 | 14 | 14 450 | 8 | 22 480 | 7 | 29 550 | 10 | 39 620 | 6 | 45 680 | 2 | 47 Here, n (total no. of workers) = 47, which is odd. All observations from 23rd to 29th are equal, each = 480. Median = ₹480 Hence, median = ₹480.
