Data collection is often costly and time-consuming. It is essential, then, to carefully consider how much data you will need to collect in order to answer your research questions. In this workshop, we will learn how to determine how much data are needed to achieve: (i) accurate estimates, (ii) informative tests of hypotheses, and (iii) optimally efficient decision making, based on the available data. Starting from the pragmatic understanding that resources are limited, throughout the workshop we will strongly focus on how to answer research questions as efficiently as possible.

We will learn how to justify the sample size to test for the presence, as well as the absence, of meaningful effect sizes, how to plan for accurate estimates, the difference between an a-priori, compromise, or sensitivity power analysis, and how to control error rates when making decisions based on limited amounts of data.

Starting July 9, we are offering this seminar as a 4-day synchronous*, livestream workshop held via the free video-conferencing software Zoom. Each day will consist of two lecture sessions which include hands-on exercises, separated by a 1-hour break. You are encouraged to join the lecture live, but will have the opportunity to view the recorded session later in the day if you are unable to attend at the scheduled time.

*We understand that finding time to participate in livestream courses can be difficult. If you prefer, you may take all or part of the course asynchronously. The video recordings will be made available within 24 hours of each session and will be accessible for four weeks after the seminar, meaning that you will get all of the class content and discussions even if you cannot participate synchronously.

Closed captioning is available for all live and recorded sessions. Captions can be translated to a variety of languages including Spanish, Korean, and Italian. For more information, click here.
