To calculate the Mean
Add the numbers together and divide by the number of numbers. (The sum of values divided by the number of values).
To determine the Median
Arrange the numbers in order, find the middle number. (The middle value when the values are ranked).
To determine the Mode
Count how many times each value occurs the highest is the mode. (The most frequently occurring value)
const meanMedianMode = new MeanMedianMode([10, 3, 3, 23, 9])
expect(meanMedianMode.getMeanMedianMode()).toEqual({ mean: 9.6, median: 9, mode: ['3'] })
