📚 Topic Summary
The mean is the average of a dataset, calculated by summing all the values and dividing by the number of values. The median is the middle value when the dataset is ordered from least to greatest. If there are 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 the dataset. A dataset can have no mode, one mode, or multiple modes.
