Abstract : Logistic ‎function‎ ‎was‎ used as a growth ‎curve for the first time in 1838. Logistic model ‎was‎ used in economic growth‎, ‎population growth studies, regression analysis natural sciences‎. ‎Because of the importance of this distribution,‎ we need optimal estimators for the ‎involved ‎parameters‎. ‎In this paper‎ ‎we ‎will ‎estimate the parameters of the ‎L‎ogistic ‎d‎istribution based on S‎imple ‎R‎andom ‎S‎ampling ‎and ‎R‎anked ‎S‎et ‎Sampling,‎ and ‎we ‎will‎ compare ‎these‎ two methods‎.
