The median is the middle value of a dataset when it's ordered from smallest to largest. If you have an even number of values, the median is the average of the two middle values. Take the numbers 1, 3, 5, 7, 9, the median would be (5+7)/2 = 6.

The mean, also known as the average, is calculated by adding up all values in a dataset and dividing by the number of values. For example, if you have the following numbers: 1, 2, 3, 4, 5, the mean would be (1+2+3+4+5)/5 = 15/5 = 3.

What's the mode used for?

The range is the difference between the highest and lowest values in a dataset. For example, given the numbers 1, 3, 5, 7, 9, the range would be 9-1 = 8.

While understanding mean, median, mode, and range can open up opportunities in various fields, there are also risks to consider:

  • Range is always the same as the difference between the highest and the lowest value, which is not necessarily true; it can be influenced by outliers.

      How it Works

      What is Mode?

    The mode is the number that appears most frequently in a dataset. If no number appears more than once, then there is no mode. For example, the numbers 1, 2, 2, 3, 3, 3, 4 have two modes, 2 and 3.
