English [Auto] In this lecture we really discuss about relative frequency and both in frequency distributions creating a frequency distribution. Tell us about the number of items in each class. However we are often interested in the proportion or both stage of items in each class. This is very relative frequency and both in frequency distributions comes in to calculate the relative frequency of a plus. We have to divide the number of items in that class by the total number of items in the dataset continuing with the example that I took in the last lecture. The relative frequency of Nike would be nineteen divided by 50 and this is equal to zero point 8 by doing the same calculation for all the classes we can get our relative frequency distribution table as shown here. Once we have got the relative frequency we just need to multiply by 100 to get deposed in frequency. Let's see what have we got now. Looking at the table presented here we can see that 30 percent of the people preferred Nike 16 percent prefer the bulk 10 percent prefer Verd line and so on. It can also be concluded that 80 percent of the people prefer Nike Reebok or Adidas.
