median vs IQR skewed data uses these for center and spread Histogram - when to use Based on the shape of the distribution, uses mean + standard deviation OR median + IQR to describe center and spread - Larger data sets; shows shapes of distribution and potential outliers; ignores the individual data valuesl Histogram Skewed right Not a symmetric distribution, the tail is on the right Standard Deviation Rule 68% of the data are within 1 standard deviation, 95% are...
