Two Approaches to Use Statistics on Your Project

Most people don't like statistics, and most decision-makers make wild guesses when they need to take a decision. Statistics might not be the most straight-forward science during the college years, but it has tremendous value in providing insights and guidance for making rational decisions.

Using statistics one can show various properties of a set of data such as the mean, mode, median, dispersion and distribution. These parameters can be represented graphically using histograms, charts and other visual illustrations.

Another approach using statistics is to develop inferences, test hypothesis and develop forecasts through the use of sample data from a bigger population. Relationships between variables can be developed and illustrated using a scatter diagram or a regression equation.
