Understanding Average Deviation
Average deviation, also known as mean deviation, measures the average absolute difference between each value in a dataset and a central point (like the mean or median). It helps to understand the dispersion or variability within a dataset.
Key Concepts:
- Mean: The sum of all values divided by the number of values.
- Median: The middle value in a sorted dataset.
- Average Deviation from Mean: Average of the absolute differences between each value and the mean.
- Average Deviation from Median: Average of the absolute differences between each value and the median.
