Most of the Danish podcasts were recorded in Spring 2015. The remaining podcasts are from previous versions of the course, and they may use other slides than those which are currently available.

Observe the following changes to the current agenda:

• “Planning a study” has been collected in Section 3.3. In the lectures below, it is included in Weeks 4 (width of confidence interval), 5, and 6 (one- and two-sample). The only change in the curriculum is that one-sided hypotheses have been removed.
• There are no one-sided tests in the curriculum at all now. In the lectures here, one-sided tests are included in Weeks 5-6 (one- and two-sample tests) and Week 10 (proportions tests).
• Week 10 about proportions used to be Week 12. It is changed in the table below, but not in the recordings. &NewLine; &NewLine;

Please note that only the current version of the Agenda counts this year. Please send an email to pbac@dtu.dk if you find things which should be changed in the table below.
