Statistics…what is it?

Statistics is the study of the collection, organization, analysis,
interpretation, and presentation of data. It deals with all

aspects of this, including the planning of data collection in
terms of the design of surveys and experiments

Three uses for statistics
 Describe (Descriptive Statistics)
 Summarize data
 Graphically
 Through formulas and tables

 Infer (Inferential Statistics)
 Use data from a small number of observations
to draw conclusions about the larger group

 Improvement (Process Studies)
 Use data from past experience to help predict
expected outcomes at a different time or place
or to direct action to influence future outcomes
