distribution properties, outlier detection, and other information. Unlike inferential statistics, descriptive statistics only describe your dataset’s characteristics and do not attempt to generalize from asampleto apopulation.

The Y variable to be explained The X explanatory variables The type of results to display (predictions, goodness of fit statistics or regression coefficients) Other arguments such as the presence of an intercept (true by default), the observations to predict (last one by default) and the observ...
In descriptive statistics, the arithmetic mean (also called the average) and standard deviation and are two closely related concepts. But while the former is well understood by most, the latter is comprehended by few. The aim of this tutorial is shed some light on what the standard deviation ...

All statistical software packages will identify the interquartile range as part of their descriptive statistics. Here, I’ll show you how to find it using Excel because most readers can access this application. To follow along, download the Excel file:IQR. This dataset is the same as the one...
Next, click on one of these tabs and then choose one of the data analysis tools from the list of options for that tab. A dialog box will then appear which is tailored to that specific data analysis tool. This is explained inUsing Real Statistics Data Analysis Tools. ...
Next we'll explore our data using descriptive statistics and probability distributions, introduce the normal distribution and empirical rule, and learn how to apply the central limit theorem to make inferences about populations of any type. From there we'll practice making estimates with confidence in...
