- The mean is always the best measure: While the mean is useful for normally distributed data, it's not always the best choice.
- The median is always more robust: While the median is resistant to outliers, it can still be affected by missing data or small sample sizes.
- What is the range? The range is the difference between the highest and lowest values in a set of numbers. It gives you an idea of the spread or dispersion of the data.
- No, each measure has a specific purpose and should be used in context.
