x̅= mean value σ = standard deviation What Is an Outlier? Outliers are values that are significantly different from other values in a dataset. An outlier is a value that is much higher or lower than the mean and median of the dataset. In an Excel graph, you can consider the data ...
Both the standard deviation and the variance mesure how far, on average, each data point is from the mean. If you were calculating them by hand, you would start by finding the mean for all your data. You would then find the difference between each observation and the mean, square all th...
