Statistics 101: Introduction to Concepts and Techniques

Business Knowledge Series course

This course introduces the basic concepts in Statistics and the techniques that can be used to address research and business questions. It discusses how to compute and interpret descriptive statistics, and how to utilize statistical graphs to picture data. Participants will learn about the inferential methods of estimation and hypothesis testing. Correlation and regression analyses are introduced, and methods for investigating categorical data are presented. Hands-on examples are provided to reinforce statistical ideas and interpretation.

Learn how to

• identify and differentiate types and uses of variables and levels of measurement
• interpret statistical concepts such measures of central tendency and variability
• use statistical graphs to picture your data
• interpret results of statistical inference such as confidence intervals and hypothesis testing
• identify the appropriate statistical procedure to answer a research or business question
• apply correlation and regression analyses to address a research or business problem
• derive insights from categorical data analysis such as Chi-square tests and logistic regression
