Median
The median is a statistical measure of central tendency that represents the middle value in a sorted dataset, dividing it into two equal halves. It is calculated by arranging all values in ascending order and selecting the middle one (or averaging the two middle values for even-sized datasets). Unlike the mean, the median is robust to outliers, making it useful for skewed distributions.
Developers should learn about medians when analyzing data with outliers or skewed distributions, such as in performance metrics (e.g., response times), salary data, or user behavior analytics. It is essential for data science, machine learning, and statistical programming tasks to provide a more accurate representation of typical values than the mean in such cases.
