Calculating the mean by adding all values and dividing by the count, with a worked example using five numbers.Finding the median by ordering values from smallest to largest and identifying the middle value in the data set.Identifying the mode as the most frequently occurring value in a data set, shown with example numbers.Calculating the range by subtracting the smallest value from the largest value in a data set.

🛎️ How to Calculate the Mean?

  • Add up all the values.
  • Divide by how many values there are.

🛎️ How to Find the Median?

  • Put the numbers in order from smallest to largest.
