Key Concepts

Median

The median is the middle value in an ordered list of numbers. As a measure of central tendency, it divides the dataset into two equal halves and is particularly useful when the data may contain outliers, as it is not as heavily affected by extremely high or low values as the mean.

Mode

The mode is the most frequently occurring value in a dataset. It provides insight into the common or peak value in the data and is a useful measure for understanding the tendency of repeated elements, especially in cases where the data is categorical or discrete.

Mean

The mean is the numerical average of a dataset, computed by summing all the values and dividing by the count of values. It serves as a measure of central tendency, providing an overall summary of the data with a single value, and is sensitive to extreme values in the dataset.
