T stat threshold
WebNonetheless past experience may lead teachers of statistics at tertiary level to surmise that threshold concepts in basic statistics will include the notion of patterns of spread or variation, randomness, sampling, the central limit theorem, and linear regression. Introductions to Bayes' theorem and interval estimation are further candidates. WebStatistical testing of a second-level analysis# Perform a one-sample t-test on a bunch of images (a.k.a. second-level analysis in fMRI) and threshold the resulting statistical map. This example is based on the so-called localizer dataset. It shows activation related to a mental computation task, as opposed to narrative sentence reading/listening.
