Abstract: Systems and methods are disclosed for an automated process for determining an optimal sample size for a contract. The method includes receiving response data including response scores to queries from data collection objects. A sampling distribution is determined for each of sample sizes based on the response scores. A significance threshold and a reliability coefficient is determined for each of the sample sizes. A probability for each of star values for the sample sizes is determined based on a cumulative distributive function of the sampling distribution and parameters of an adjustment grid. An expected star value for each of the sample sizes is determined based on the probability determined for each of the star values. The expected star value is presented in a user interface of a device, wherein at least one of the sample sizes with a highest expected star value is recommended as the optimal sample size.
