Mode, median, and mean are statistical measures used to describe and analyze data.

- Mode: The mode is the value(s) that appear most frequently in a dataset. To find the mode, you can simply list the data points and see which one(s) appear(s) most often. For example, in the dataset {1, 2, 2, 3, 4, 4, 4}, the mode is 4 because it appears three times.

- Median: The median is the middle value in a dataset when it is ordered from least to greatest. If the dataset has an odd number of values, the median is the middle value. If the dataset has an even number of values, the median is the average of the two middle values. For example, in the dataset {1, 2, 3, 4, 5}, the median is 3. In the dataset {1, 2, 3, 4, 5, 6}, the median is (3 + 4) / 2 = 3.5.

- Mean: The mean, also known as the average, is found by summing up all the values in a dataset and then dividing by the total number of values. For example, in the dataset {1, 2, 3, 4, 5}, the mean is (1 + 2 + 3 + 4 + 5) / 5 = 3.

These measures provide different perspectives on the central tendency of the data. The mode reveals the most frequently occurring value, the median gives the middle value, and the mean provides the average value.
