1 EXPERIMENT VS. CORRELATIONAL STUDY

2 EXPERIMENT Researcher controls all conditions
Experimental group – 1 or more groups of subjects Control group – controlled condition where participants may receive a placebo or no treatment at all (used as the standard for comparison) ONLY EXPERIMENTATION IMPLIES CAUSATION EXPERIMENT

3 Stronger relationship: 1.0
Used when a controlled experiment can’t be done Can NEVER be 100% sure groups are similar in every way  can NEVER say the condition was the cause of the effects you observed DOES NOT IMPLY CAUSATION Correlation coefficient – set of scores to find the closest correlation between 2 variables Stronger relationship: 1.0 weak relationship: 0.0 Positive correlation – both variables increase or decrease; negative correlation – one increases and the other decreases CORRELATION
