A. The correct answer is "A" because criminal justice research involves estimating population parameters on the basis of sample observations. The summary description of a given variable in the sample is called a sample statistic. Sample statistics are used to make estimates of population parameters. For example, the average income computed from a sample and the age distribution of that sample are statistics, and those statistics are used to estimate income and age parameters in a population.
B. This is an incorrect answer because criminal justice research involves estimating population parameters on the basis of sample observations. The summary description of a given variable in the sample is called a sample statistic. Sample statistics are used to make estimates of population parameters. For example, the average income computed from a sample and the age distribution of that sample are statistics, and those statistics are used to estimate income and age parameters in a population.
