Trying to make sense of Microsoft Excel’s statistical analysis tools? Make sure you understand the statistical terms Excel uses, says bestselling computer book Excel provides an almost countless number of statistical tools you can use to analyze data and make meaningful statements about it. However, without understanding the definitions of the statistical terms that Excel uses, the statistical tools offer little help. Accordingly, this article supplies some background information about Excel’s statistical tools and also defines the important statistical terms used by Excel.
Need to work with binomial probability distributions? Don’t forget that Microsoft Excel supplies powerful tools for performing just this sort of statistical analysis. A binomial distribution describes the outcome of a multi-step experiment, consisting of n identical trials, where each trial ends in either a success or a failure and the probability of a success p does not change from trial to trial.

Need to make Beta Probability calculations? Microsoft Excel supplies two useful statistical functions for making just these sorts of calculations, BETADIST and BETAINV. Microsoft Excel supplies two useful statistical functions for making beta probability calculations, BETADIST and BETAINV. Perhaps surprisingly, neither function is difficult to use as long as understand the inputs that supply data to the function. Understanding the beta probability density function, BETADIST The BETADIST function returns the cumulative beta probability density function. Statisticians often use the cumulative beta probability density function to study variation across samples, such as when comparing two groups of people performing the same task to see whether they have the same success rate.
Need to count the cells in a worksheet range that contain data averages? Microsoft Excel supplies several easy-to-use functions for just such a purpose says bestselling computer book If you select a range of cells, you can have Excel find how many cells are in that range using the count functions. This sounds a little goofy, but a handful of easy-to-understand examples show how this works–and suggest when you might want to use the “cell counting” functions. COUNT
