OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.

Description
1. Experimental Design  Experimental Design o True experiments (random assignment of participants to experimental groups) provide the strongest evidence for claims to knowledge. o It provides a systematic way to isolate the effect of an IV (i.e. intervention) because groups are more or less equal in all respects except for the receiving different levels of the IV. o Use of a control group allows for strongest support for “cause” and “effect” (X causes Y).  Basic Experiments o Posttest Only  Obtain two equivalent groups.  What does ‘selection differences’ mean?  Introduce the IV and select two levels.  Like what?  Measure the effect of the IV on the DV.  Basic Experiments o Pretest-Posttest Design  It is similar to the posttest only design, but the dependent variable is measured prior to introducing the IV.  It allows researchers to determine if groups are equivalent at the start of an experiment.  It is also useful if attrition is a potential problem.
