Causation and Correlation
Correlation does not imply causation. According to “statistical Language Correlation and Causation” (Correlation is a statistical measure (expressed as a number) that describes the size and direction of a relationship between two or more variables. A correlation between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable.) And (Causation indicates that one event is the result of the occurrence of the other event; i.e. there is a causal relationship between the two events. This is also referred to as cause and effect.) Causation and correlation can be difficult to discern from one another because they are so closely related to one another. Wealthy People are thin. Causation or correlation? The statement “Wealthy people are thin” is a correlation. Not all wealthy people are thin however there may be more thin wealthy people versus non wealthy people due to the fact that wealthy people can afford personal trainers, better food, and healthier lifestyles.

Students with fewer clothes perform worse on standardized tests. Causation or correlation?

We cannot deduce causation from correlation: correlation does not imply causation. The main problem with all correlations is that there are many models consistent with any correlation: the correlation between two variables may be caused by a third, fourth, or dozens of variables other than the two being compared. Therefore we are left with numerous substitute models in addition to the obvious ones.…

Every morning around sunrise, the rooster crows. Does the rooster cause the sun to rise? Not likely. But, if we were to track and plot the sunrises and rooster crows every morning for a year, it would be evident that they occur concurrently. This is an association. So, then, does the sunrise cause the rooster to crow? Not necessarily. A spurious association is an association between two variables that can be better explained by a third lurking, or hidden variable. In this case, the lurking variable is territorial advertising. "Roosters crow every hour, on the hoursaying, This is my coop, get the heck out of my way, don 't mess with my women. ' If a truck goes by, the rooster interprets the noise as that of an intrusion by another rooster. If most of the crowing takes place in early morning, it is because that is when there is the most activity." (Feldman, 1990, pp. 51-52). As you can see, association can be easily confused with causation.…

The four main purposes of punishment in the criminal justice system are: Deterrence - this is something intended to discourage someone from commiting a crime through instilling fear as to the consequences for their actions. There are two types of deterrence - specific deterrence and general deterrence. Retribution - its purpose of punishment is to administer justice - a deserved or morally right consequence to the offender that committed the crime. Rehabilitation - this punishment aims to reform an offender’s behaviour from reoccurring and prevent recidivism. This is achieved by conducting sentencing options and programs including anger management courses, alcohol programs as well as drug rehabilitation and counselling programs.…
