Imagine you have a set of exam scores, and you want to understand the central tendency of the group. The mean is the average score, calculated by adding up all the scores and dividing by the number of students. However, the mean can be skewed by extreme values, making it less representative of the overall data. That's where the median comes in – it's the middle value of the data set when it's arranged in order. The median is a better indicator of central tendency when the data is not normally distributed.

Rounding errors, incorrect calculations, and overlooking data distribution can all lead to misinterpretation of the data.
