Document Summary
Correlation: a variable is a concept that can have more than one value, a correlation is the relationship or association between two variables, the correlation coefficient ( r ) measures the strength of the association between two variables. Its value ranges from -1 to + 1, with -1 indicating a perfect negative linear association, +1 indicating a perfect positive linear association, and 0 indicating no association. coincidence: events, including correlations, may be due to coincidence for example, you may toss a coin and get heads, and then toss it again and get heads. This is a sufficiently rare event that we suspect the event is not due to chance: we study statistics partly to know the chance that events, including correlations, are likely to be real or coincidental. spuriousness: a correlation may also be spurious (or phony) if it is preceded by the real cause of the correlation.
