What Does Outlier Mean in Math?


What does outlier mean in math? I'm Bon Crowder and we're talking about the outlier today. It's a statistic term that typically means some data point that's way far away from the rest of the data points. It doesn't have a specific definition. It kind of depends on context. So in this data set this guy would almost for sure be considered an outlier. And depending on the context and how far out you want your outliers, this guy might even be considered an outlier. Sometimes we consider outliers as two or three standard deviations above the mean when we're talking about a normal curve or a normal distribution of data points. So it really just means somebody that's way not part of the group and pretty far away from the average, either above or below. I'm Bon Crowder and that's what an outlier is in math.
