While using excel frequency distribution make sure that classes should be in equal size with an upper limit and lower limit values. In the case of an even number of terms, the median is the average of the two middle terms. Hence to find the mean we need a single value that can represent the interval. Calculate Median using following Formula M = L + ( \( \frac{n}{2} \) – cf) \( \frac{h}{f} \) Where, L is Lower limit of Median Class. Weights of ear heads ( in g) No of ear heads (f) Less than class Cumulative frequency (m) 60-80 22 <80 22 80-100 38 <100 60 100-120 45 <120 105 120-140 35 <140 140 In excel Frequency distribution, while grouping we might lose some of the data, hence make sure that we are grouping in a proper manner. Learn how to find the median of a continuous frequency distribution from this video. ADVERTISEMENTS: It is series that deals with discrete variables. Gerald -- the median() function doesn't work here because you actually have to list out all your values (like i did in my parentheses, like 6,5,5,5,2,2,2,2,2,1 only 1 per cell), it won't calculate from a frequency distribution table like this. For the data set 1, 1, 2, 6, 6, 9 the median is 4. Median from an Ogive Curve. If you have an odd number, divide by 2 and round up to get the position of the median number.
