Since simple random sampling involves selecting observations at random from a population, the values of the statistic (e.g. mean, standard deviation) will vary from sample to sample due to chance. This variability is the basis of statistical inference, which allows us to use sample statistics to make decisions or draw conclusions about the population parameter. Therefore, it is expected that different samples will produce different values of the statistic.
