what are 2 things you know about IQR(interquartile rage)and MAD(mean absolute deviation)
1. IQR (interquartile range) is a measure of statistical dispersion, which represents the range of the middle 50% of a dataset. It is calculated by subtracting the first quartile (25th percentile) from the third quartile (75th percentile) of the data.
2. MAD (mean absolute deviation) is a measure of variability that calculates the average of the absolute differences between each data point and the mean of the dataset. It provides a more robust measure of dispersion compared to standard deviation, as it is less sensitive to outliers.
