The frequency of the median class
WebTherefore, the median class is 15-20. Step 3– after finding the median class, find the values to be put into the formula. Lower limit of the median class (l)= 15. Cumulative frequency of preceding class(cf)= 17. Frequency of the median class(f)= 10. Height of the class (h)= 5. Step 4– Substitute the values into the formula. Median= 15+ (20 ... WebBased on the data, using we can know that the median is 2.5, without calculation. If using the formula as mentioned above, n 2 will get 2, there for the class contains the median is class 2, then using L m is a lower boundary, m e d i a n = 1.5 + [ 2 − 1 1] × 1 = 2.5 This doesn't make sense for using lower limit.
