          The right measure depends on the context and purpose. Mean is often used for continuous data, like temperatures. Median is a better choice for skewed distributions, such as income levels. The mode can be useful for categorical data, like favorite colors.

          For instance, consider the following set of exam scores: 70, 85, 90, 95, and 90. To calculate the mean, add them all together (70 + 85 + 90 + 95 + 90 = 330) and divide by 5, resulting in 66. The median would be 90, as 90 is the middle number when sorted. In this case, the mode is 90 since it appears twice.
