Since we considered all math classes to be the population , then the average number of points earned per student over all the math classes is an example of a parameter . One of the main concerns in the field of statistics is how accurately a statistic estimates a parameter . The accuracy really depends on how well the sample represents the population . The sample must contain the characteristics of the population in order to be a representative sample . We are interested in both the sample statistic and the population parameter in inferential statistics .
