C. Hall Jones & Associates can effectively employ a number of statistical analysis techniques to aid in the collection, organization, classification, summarization, interpretation, and presentation of data, making inferences, testing hypotheses, determining relationships, making predictions about a sample or a population, and making decisions under uncertainty.
Statistics is often defined as the science of collecting, organizing, summarizing, analyzing, and making inferences from data. Statistics is a collection of theories and methods that are applied for the purpose of understanding data.
The application of statistics may be beneficial:
- In conjunction with research to fully understand the results and how those results affect future course and/or program design and application.
- To determine various factors from sets of data that have been obtained from tests that have been applied to a single group.
- To determine various factors from sets of data that have been obtained from tests that have been applied to mulitple groups.
The application of statistics is divided into three broad categories:
- Descriptive statistics
- Inferential statistics
- Decision theory
Descriptive statistics includes collecting, organizing, classifying, summarizing, and presenting data.
Inferential statistics includes making inferences, hypothesis testing, determining relationships, and making predictions about a population by analyzing a sample from that population.
Decision theory includes making decisions under uncertainty.
