Quick Tips

  • •Double-check your inputs — a single outlier can dramatically change the mean and standard deviation.
  • •Compare the mean and median to quickly assess whether your data is skewed.
  • •Use the IQR (Q3 minus Q1) for a robust measure of spread that is less sensitive to outliers than standard deviation.
