more on mean and median
summary
understanding the relationship between mean and median is crucial for interpreting data sets, especially in the context of outliers and symmetry.
- the mean is significantly influenced by outliers, whereas the median remains unaffected.
- mean and median are equal in cases of evenly spaced numbers or symmetrical distributions.
- outliers can cause the mean to deviate from the median, pulling it in the direction of the outlier.
- in asymmetrical lists, the mean and median will differ, with the mean being more sensitive to changes.
- it's possible to compare mean and median without direct calculation by analyzing the distribution and direction of outliers.
