A recent study conducted compared two strategies that are designed to reduce violence among inmates in large prisons. Strategy A involved counseling (e.g. crisis intervention). Strategy B involved punishment (e.g. solitary confinement). Violent confrontations were measured in two similar prison settings prior to and then after the implementation of either strategy. The researchers used a t-test to compare the before and after violent incidents at each prison. The statistical significance of these t-tests is below and represented as a p value. REMEMBER, statistical significance (also called p value) represent the probability that a statistical change is due to chance. Normally, a p value of 0.05 is considered acceptable, however, this standard can be ignored if change is more dramatic and one is not as concerned about error.

In Prison A (which used Strategy A) violent incidents reduced 57 percent, p=0.10.

In Prison B (which used Strategy B) violent incidents reduced 30 percent, p=0.04.

Write a brief (one page) recommendation to the warden on which of these two strategies you would implement. If you choose Strategy A (because it resulted in a higher level of reduction in violent confrontations) explain why you are ignoring that the t-score is not statistically significant. If you choose Strategy B (because the t-score is statistically significant) explain why you are ignoring the higher level of reduction in violent incidents associated with Strategy A.
