Box plots can help you compare data, identify outliers, and assess normality. Learn how to create box plots in Excel, Minitab, or R, and how to use them for Six Sigma projects.

Note that the PROBPLOT statement creates a normal probability plot for DIAMETER by default. The nonlinearity of the point pattern indicates a departure from normality. Since the point pattern is ...

Graph of the Normal Distribution. In a normal distribution, values are most concentrated around the mean, and the probability decreases smoothly as you move further away in either direction. The ...

A Price Probability Plot that overlays the Price Frequency data with a normal distribution plot calculated at the last available price (as mu) and historical standard deviation (as sigma). Code: price ...

Most-frequent values are clustered around the mean (which here is same as the median and mode) and fall off smoothly in either side of it. In normal distribution, 68 percent of all values lie within ...

When a dataset from a non-negative random variable contains zero or very small observations, the folded-normal distribution (FND) can be an appropriate model for fitting the data. Such data includes ...
