Var(X): Variance (Var) is another measure used to quantify variability in data. It is calculated by averaging squared differences between each value and its mean.
Range: Range refers to the difference between the maximum and minimum values in a dataset. It provides a simple measure of the spread of data but does not consider individual deviations from the mean.
IQR (Interquartile Range): The interquartile range is a measure of statistical dispersion, specifically for quartiles. It represents the range between the first quartile (25th percentile) and third quartile (75th percentile) and is less sensitive to outliers compared to the range.
