Library Assessment Tips & Techniques: Statistical Analysis

Introduction

There are two types of statistics required to analyze data generated by tests, surveys, and other quantifiable methodologies:

Descriptive Statistics

  • Reporting or describing summary data without drawing any conclusions, such as total number and percent who answered a question a certain way. Typically, descriptive data is presented in summary tables or graphs.

Inferential Statistics

  • After the use of appropriate tests and correlations, data is presented as predictive or causative of a certain behavior, generalized to a population, or confirming or dis-confirming a test of a hypothesis.
