Description
Sometimes the answer is not just about the measures of central tendency or dispersion of one set of data. It could be in the intersection or relationship between two or more data types. In the criminal justice field, its important understand how to use data analysis with multiple variables to solve problems or make decisions.

1)Finding the variables that have an effect on an interest issue can be done with accuracy using regression analysis. Regression analysis is amazing since it actually makes it possible for us to forecast the future based on historical trends. Regression analysis, however, has a lot of drawbacks. First off, fresh examples or new circumstances might not be affected by past correlations. This can be applied to policing, criminal courts, and corrections by collecting and analyzing previous data, we can see the pattern in which crimes have been committed. Looking at demographics , race, gender it could assist in what areas need more assistance.
In a situation where the probability of all outcomes is uncertain, the quantitative method involves applying mathematical and statistical models to arrive at the best decision. In other words, it aids managers in finding solutions to difficult issues during decision-making. The advantage of quantitative approach techniques, particularly those that use statistical software, is that they can recommend the optimal answer to a problem without even identifying all potential solutions. The more options to issues within policies, the quicker they can be modified to be successful .

Correlation analysis is applied in quantifying the association between two nonstop variables, for illustration, an dependent and independent variable or among two independent variables. Retrogression analysis refers to assessing the relationship between the outgrowth variable and one or further variables. The outgrowth variable is known as the dependent or response variable and the threat rudiments, and co-founders are known as predictors or independent variables. The dependent variable is shown by y and independent variables are shown by x in retrogression analysis. The sample of a correlation measure is estimated in the correlation analysis. It ranges between-1 and 1, denoted by r and quantifies the strength and direction of the direct association among two variables. The correlation among two variables can either be positive, i.e. an advanced position of one variable is related to an advanced position of another or negative, i.e. an advanced position of one variable is related to a lower position of the other. The sign of the measure of correlation shows the direction of the association. The magnitude of the measure shows the strength of the association
