Abstract：In this paper , the lower Limit of the sample size in f requency statistics of chinese characters is given by using the method named error estimate under the conditions of giving the error bounds and the confident probability , a new statistical method of frequencies of chinese characters is presented in which the defined statisfical f requency of a chinese character is unbiased and has a smaller variance than before and therefore is a preciser estimate of utility frequency of the chinese character.
