As far as the future is concerned, there is not much confidence in the prediction. Making a prediction using a trend line equation is based on two main factors which are a relationship between the factors in question as well as the trend line being in a linear state (Judge, 2017). A closer examination of the data indicates that the number of individuals in both probation and parole is not constantly increasing. The numbers reach a point where they start to decrease. In this case, it would not be advisable to predict the future based on a trend that will decrease in the future. In addition to that, the numbers might keep on decreasing as a result of the rules involving parole and probation violations. Parole and probation violations contribute to nearly half of the prison population (Walshe, 2012).
From the box and whisker graph created, the main measure of central tendency examine is median. The median value for both sets of data is 4,053,600 for probation and 824,100 for parole. Form the data, it is clear that probation and parolees for the years examined range from 3,000,000 to 4,300,000 for probation and between 7,00,000 to 9,00,000 for probation.

As for the project in general, it is clear that the number of individuals is decreasing from the year 2007 for probation and 2012 for parole. The mean for the data relating to probation and parole is 4,058,667, and 805,687 respectively.
