How do you solve for frequency
WebFeb 9, 2015 · You express the cumulative frequency as fraction or percentage of the total sum of frequencies Simple example Say you have frequencies: 1 − 3 − 4 − 8 − 3 −1 for 6 different values (total 20) Then your relative frequencies will be: 5 % − 15% − 20% − 40% −15% −5 % Your cumulative frequencies will be: 1 − 4 − 8 − 16− 19 −20
