PSY379H5 Lecture Notes - Lecture 3: Linear Function, Bar Chart, Abscissa And Ordinate
Document Summary
Plan for today: how to plan a single-variable experiment, how to plan a multi-variable experiment, how to interpret experimental results. Softer ceiling effect: difficult to know your ceiling. Still single-variable experiment but multi-level: ex print size = variable, ex 5 font, 10 font, 12 font, 14 font, will give much better idea of the functional rel, 2-level vs multi-level. Study of anxiety on test performance: 2-level. Low vs high anxiety: high ---> gets 1 class high on anxiety, 5 mins before gives talk re: h/ important test is. Low vs normal vs high: normal, gave speech but about test procedure and other things. Interpretation a lil more complicated: don"t know i diff levels are diff from each other, for ex. Factitious results that don"t hold for any one subject: single-subject & small-n baseline designs. Individual vs grouped data: baseline procedures, learning by analogy study.
