Basic stats with SPSS

What is it about?

This paper is the first of a short series of articles aimed towards describing some of the various statistical methods and approaches that have been used in surface finishing. The methods fall broadly into two areas: analysis and design-of-experiments. This article introduces the subject, briefly reviewing the wide use of a number of experimental design tools in recent surface finishing research before starting with a discussion of parametric hypothesis testing, the simplest of the statistical methods.

Why is it important?

The understanding and use of statistics is important in all research methods. This paper is the first in a series and it describes the basics. Non-parametric stats will follow in Part 2 (early 2019) and more advanced topics will follow in due course.
