One Final Assessment

Real world data is frequently ambiguous

  • We build practical understanding of the most important statistical tools used to differentiate the one from the other, whether the data is quantitative or categorical.
  • Very little theory is presented; rather, the focus is on selecting appropriate tools and correctly interpreting the results.

Details Of What You Will Learn

During This Course

  • Have strong intuition into variability and bias in real-world sample data
  • Understand the fundamental logic of statistical inference
  • Possess a toolkit of essential techniques for analyzing categorical and quantitative variables
  • Recognize statistical abuse and be able to avoid it in practice
  • Be prepared to quickly learn any of the various specialized inference techniques they might encounter in their future work with data

This Course Module is Tailored for:

Data Analysts

Reporting Managers

Excel Users

Anyone working with data and attempting to draw constructive, generalizable conclusions from them.

Participants of this course must have a basic knowledge and understanding of variable types and descriptive and inferential statistics. No other advanced preparation is needed to take this course. Although the demonstrations in the course are done in R, they are intended to be generalizable to Python or any other statistical software you choose to use. Knowledge of R is not a prerequisite for taking this course.
