What Data Can Tell Us [F-14-65]

How can we tell whether an effect observed in sample data (for example, mosquitoes were more attracted to beer drinkers in an experiment on malaria transmission) represents a real effect in the population or is just due to “random chance”? We will look at ways to use new and straightforward computer simulations to answer such questions of statistical inference with simple, intuitive techniques that require very little formal background. The simulations are done using StatKey, a free web app we have developed to facilitate understanding of the key ideas of statistical inference.

Robin and Patti Lock have both taught mathematics and statistics at SLU for more than 30 years. Together with their three children (Kari, Eric, and Dennis – all statisticians!), they have developed a new statistics text (and the web app StatKey) to allow instructors to introduce the core ideas of statistical inference with modern computer-based simulation methods.

NOTES: 1) No statistical background is assumed
