The average business has radically changed over the last decade.

Whether it's the equipment used at desks or the software used to communicate, very few things look the same as they once were.

Something else that is completely different is how much data we have at our fingertips. What was once scarce is now a seemingly overwhelming amount of data. But, it's only overwhelming if you don't know how to analyze your business's data to find true and insightful meaning.

So, how do you go from point A, having a vast amount of data, to point B, being able to accurately interpret that data? It all comes down to using the right methods for statistical analysis, which is how we process and collect samples of data to uncover patterns and trends.

For this analysis, there are five to choose from: mean, standard deviation, regression, hypothesis testing, and sample size determination.
