Mean = (sum of all numbers/items)/(no. Hence, figure is = 20. We have a median, lower limit. Σfx = 2060 + 30f 1 + 70f 2. ⇒ 30 f 1 + 70f 2 = 2520. Use the formula (# +#)/2=median and solve. Then f1+f2 t o al frequency−sum of the given frequency. 3f 1 + 3f 2 = 156. Substitute this value of x in equation (1) to get the value of y.

Mean = (sum of all numbers/items)/(no. ⇒ 3 f 1 + 7f 2 = 252 → (2) multiply equation (1) with 3, we get. Mean = 2× 1 + 5× 2 + 4× 3 + 2× 4 + 1× 5 (how many numbers) and rather than count how many numbers there are, we can add up the frequencies: Σf = 30 + f 1 + f 2. Find the missing frequencies and the median for the following distribution if the mean is 1.46. Of number/items) so, take the sum of all objects and divide it by no. Let the missing frequencies be x and y. 50 = 30 + f 1 + f 2. 3f 1 + 3f 2 = 156 → (3) subtract (3) from (2), we get.
