Graphs help statisticians to visualize data. But not all graphs are created equally. Different situations call for different depictions of data. Learn more about seven of the most common graphs in statistics, and when you should use them.
Most practical applications of statistics require some kind of aid for calculations. There are a number of statistical software packages available for use. One of these is Microsoft Excel.
Some of the more basic calculations in statistics are that of the mean and standard deviation. See how to use Excel to calculate the mean of a data set with the AVERAGE function and standard deviation with the STDEV.S function.
One area of statistics, called mathematical statistics, examines the theoretical underpinnings of statistics. This requires careful, logical proof and results from other areas of mathematical, such as calculus. One operation in calculus is called the derivative. There are a number of formulas for derivatives including:inflection points of the normal distribution, or to perform calculations with the gamma function.
