1. Mean and median are both measures of central tendency in a dataset.
2. The mean is calculated by adding up all the values in a dataset and dividing by the total number of values.
3. The median is the middle value in a dataset when the values are arranged in numerical order.
4. The mean is affected by extreme values (outliers) in a dataset, while the median is not as affected by outliers.
5. In a symmetric distribution, the mean and median will be the same value. In a skewed distribution, they may be different.
6. The mean is commonly used in making comparisons and calculations, while the median is often used to represent the middle value of a dataset.
7. The mean is used in calculating variance and standard deviation, while the median is not used in these calculations.
8. In a dataset with an even number of values, the median is calculated by taking the average of the two middle values.
