Calculating the mean, median, and mode are basic statistical techniques that are used in a variety of fields, including medicine. Understanding these concepts is essential for medical professionals looking to analyze data and make informed decisions. In this tutorial, we will walk you through the steps to calculate the mean, median, and mode, and how they can be applied in medical research and practice.
Mean
The mean is a measure of central tendency that represents the average of a set of numbers. To calculate the mean, you simply add up all the numbers in the dataset and divide by the total number of values. For example, if we have a dataset of [10, 15, 20, 25], the mean would be calculated as follows:
(10 + 15 + 20 + 25) / 4 = 17.5

Median
The median is another measure of central tendency that represents the middle value in a dataset when the values are arranged in numerical order. To calculate the median, you simply need to find 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 [10, 15, 20, 25, 30], the median would be 20.
Mode
The mode is the value that appears most frequently in a dataset. To calculate the mode, simply identify which value occurs most often. In some datasets, there may be more than one mode, known as a bimodal or multimodal distribution.
