Learning Guide

These are the three main measures of central tendency - they help describe the center or typical value of a dataset.

The mean is calculated by adding all values and dividing by the count. It's sensitive to outliers.

Mean = Sum of all values / Number of values

Example: For data [2, 4, 6, 8], Mean = (2+4+6+8)/4 = 5

The median is the middle value when data is sorted. It's more robust to outliers than the mean.

Example: For [1, 3, 5, 7, 9], Median = 5

The mode is the value that appears most frequently. A dataset can have:
