If there's an even number of values, the median is the average of the two middle values. The mode is the value that appears most frequently in a dataset. A dataset can have no mode, one mode (unimodal), or multiple modes (bimodal or multimodal). 4. Comparing the Three Measures Each measure of central tendency has strengths and weaknesses. Here's when to use each one:
