What are descriptive statistics used for?

Descriptive statistics are primarily used to summarize and describe the characteristics of a dataset. This form of statistical analysis provides a way to present the essential features of data in a clear and understandable format, allowing researchers to convey complex information easily. For instance, descriptive statistics can include measures such as mean, median, mode, standard deviation, and range, which help in understanding the distribution, central tendency, and variability within the data.

This summarization is vital in criminal justice research as it allows practitioners and researchers to convey essential insights about crime trends, demographic information, or recidivism rates without delving into predictive modelling or causal analyses. By focusing on these descriptive measures, analysts can offer a foundation for further research or policymaking decisions, ensuring that any subsequent interpretations or decisions are grounded in a solid understanding of the data at hand.
