# Mean median mode calculator

The mean, median, and mode are measures of central tendency in statistics. They are used to describe the typical or representative value in a set of data.

• The mean is the average of all the numbers in a set of data. It is calculated by adding up all the numbers and dividing by the total number of numbers.
• The median is the middle value in a set of data when the data is arranged in numerical order. If there is 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 a set of data.

To calculate the mean, median, and mode of a set of data, you can use the following steps:

1. Input the data set into the calculator.
2. Calculate the mean by adding up all the numbers and dividing by the total number of numbers.
3. Calculate the median by arranging the numbers in numerical order and finding the middle value. If there is an even number of values, find the average of the two middle values.
4. Calculate the mode by finding the value that appears most frequently in the data set.
5. The calculator will display the mean, median, and mode of the data set.

Note that the mean, median, and mode may not always be the same value, and each measure provides different information about the data set.

### Here are the steps to calculate the mean, median, and mode of a set of numbers:

Example: Find the mean, median, and mode of the following set of numbers: 3, 5, 2, 8, 6, 2, 7, 2, 9.

1. Mean: To calculate the mean, you need to add up all the numbers in the set and then divide the sum by the total number of numbers.

Addition: 3 + 5 + 2 + 8 + 6 + 2 + 7 + 2 + 9 = 44 Divide by the total number of numbers: 44 ÷ 9 = 4.88889 (rounded to 2 decimal places, the mean is 4.89)

1. Median: To find the median, you need to arrange the numbers in order from lowest to highest and then find the middle number. If there are two middle numbers, you need to find their average.

Arrange the numbers in order: 2, 2, 2, 3, 5, 6, 7, 8, 9 The middle number is 5.

1. Mode: The mode is the number that appears most frequently in the set.

In this example, the mode is 2 because it appears three times, which is more than any other number in the set.

Therefore, the mean is 4.89, the median is 5, and the mode is 2 for the set of numbers given.
