... Mean and standard deviation are more precise (since based on actual data values); have nice mathematical properties but not resistant. Median and IQR are less precise (since based only on positions); are resistant to outliers, errors and skewness. ...

... 1. How are the central tendencies of mean and median alike? When is more appropriate to use each one? 2. How are the interquartile ranges useful when describing data sets? 3. What is a normal distribution? 4. What is the probability that a random variable fall in a given interval in a normal distrib ...
