Calculating Power and the Probability of a Type II Error (A Two-Tailed Example) @jbstatistics

Uploaded July 2013 | Updated September 2026, 2 hours ago

An example of calculating power and the probability of a Type II error (beta), in the context of a two-tailed Z test for one mean. Much of the underlying logic holds for other types of tests as well.

I have a related video with a one-tailed Z test example available at youtu.be/BJZpx7Mdde4.
