Course Description

This course provides an introduction to basic statistical concepts and techniques used for the collection, organization, analysis, and presentation of various types of data. The course touches on both descriptive statistics and inferential statistics, including how to compute measures of central tendency and dispersion, and how to assess the relationship between two variables.

Additional topics include graphical representation of data, least squares regression and correlation, calculating probabilities and evaluating probability and sampling distributions, hypothesis testing, confidence intervals and statistical inference, and drawing conclusions about the underlying population. Practical application of these statistical concepts and techniques to various requirements in ISO/IEC 17025 and ISO/IEC 17020 will be demonstrated.
