Mean is calculated by adding up all the values in a dataset and dividing by the number of values. To find the mean, add up all the numbers in the dataset and divide by the total number of values.

Median is the middle value in a dataset when the data is arranged in numerical order. To find the median, order the numbers from smallest to largest and then find the middle value. If there are two middle numbers, find the average of those two numbers.

Mode is the value that appears most frequently in a dataset. To find the mode, determine which value appears most often in the dataset.

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

The mean is the average of the values in a data set. It is found by adding all the values in the data set and then dividing by the number of values.

The median is the middle value in a data set that has been arranged in order from least to greatest. If there are two middle values, the median is the average of those two values.

The mode is the value that occurs most often in a data set.

Here are some examples:

  • The mean of the data set {2, 4, 6, 8} is 5.
  • The median of the data set {2, 4, 6, 8} is 6.
  • The mode of the data set {2, 4, 6, 8} is 6.

Here are some steps to find the mean, median, and mode of a data set:

  1. List the data in numerical order.
  2. Find the mean by adding all the values in the data set and then dividing by the number of values.
  3. Find the median by finding the middle value in the data set. If there are two middle values, find the average of those two values.
  4. Find the mode by finding the value that occurs most often in the data set.

Here is an example of how to find the mean, median, and mode of a data set:

Data set: {2, 4, 6, 8}

  1. List the data in numerical order: {2, 4, 6, 8}
  2. Find the mean by adding all the values in the data set and then dividing by the number of values: 2 + 4 + 6 + 8 = 20 / 4 = 5
  3. Find the median by finding the middle value in the data set. The middle value is 6.
  4. Find the mode by finding the value that occurs most often in the data set. The mode is 6.

The mean, median, and mode of the data set {2, 4, 6, 8} are 5, 6, and 6, respectively.
