Course Description

This course provides a practical introduction to statistics and inference. Participants will learn the difference between the population parameters we want to know, and the statistics from samples that estimate them. In addition, participants will be able to use summary statistics to describe the central value and spread in a distribution.

The course will demonstrate how to design an experiment, including an estimate of sample size, to determine if the means of two populations are different. Lessons incorporate both lecture and hands-on exercises with a focus on cultivating practical skills.

We offer in-person training, as well as remote training via our Live Online technology. We are able to blend these capabilities so we can teach your entire team, even if they’re not all in one place.

Course Outcomes

Upon completion of the course, attendees should be able to:

Use statistical inference to estimate the mean of a population with a confidence interval from information provided in a random sample

Gain a working conceptual understanding of probability distributions and the cumulative distribution function

Select the appropriate probability distribution for classical probability problems

Distinguish between statistics calculated on samples and expectations calculated on distributions

Have a working conceptual understanding of the central limit theorem and the law of large numbers

Distinguish between the concepts of correlation and causation

Articulate the difference between Type I and Type II errors

Gain a working conceptual understanding of hypothesis tests

Perform hypothesis tests and A/B tests

Design experiments that have sufficient statistical power to calculate an effect of interesting size
