What is the purpose of experiments?
00:08
Manipulating/Observing Variables Trying to find relationships Trying to find causality
00:24
Parts of an experiment:
00:25
Independent Variable (IV) Dependent Varible (DV) 
00:35
Manipulate
00:42
Two levels
00:45
Dependent Variables
00:46
Dependent Variables  
00:50
Changes based on manipulation of the IV
00:56
Named "Dependent" due to it directly depending on IV
01:03
Advantages of Experimental Method:
01:05
Prove Causality
01:07
(Changing IV will impact DV)
01:09
Milgram's Experiment
01:11
IVs: If the reasearcher was in the room  and how close they were to the participant
01:21
DV: If participant kept shocking
01:32
What is a Hypothesis?
01:34
Prediction how IV will impact DV  
01:45
Different kinds of Hypothesis
01:47
Non Directional
01:51
Manipulation will cause a change in DV
01:57
Directional
02:03
Increas/Decrease in IV increase/decreases DV
02:09
Importance of Control groups:
02:10
Not given the manipulation
02:10
lets researchers see if the IV is
02:10
the one impacting DV
