The number of classes can be estimated using the rounded output of Sturges rule N 13322logn N 1 3322 log n where N N is the number of classes and n n is the number of items in the data set. Let us look at some examples to understand how to calculate marginal relative frequency. Relative frequency is a measure of the number of times a particular value results as a fraction of the full set.
You add the frequencies up to and including for the value.
The number of classes can be estimated using the rounded output of Sturges rule N 13322logn N 1 3322 log n where N N is the number of classes and n n is the number of items in the data set. The Frequency of winning is 9. Count your full data set. Since there are two 3s write 2 underneath Frequency on the same row.
