Sure! Here's a clear explanation of mean , median , mode , and range in statistics:

Mean

  • The mean is the average of a set of numbers.
  • To find the mean, add up all the numbers and then divide by how many numbers there are.
  • Example: For the numbers 2, 3, 5, 7, 10
    Mean = (2 + 3 + 5 + 7 + 10) ÷ 5 = 27 ÷ 5 = 5.4

Median

  • The median is the middle value when the numbers are arranged in order.
  • If there is an odd number of values, the median is the middle one.
  • If there is an even number of values, the median is the average of the two middle numbers.
  • Example: For the numbers 2, 3, 5, 7, 10 (already in order)
    Median = 5 (the middle number)
    For 2, 3, 5, 7, 10, 12
    Median = (5 + 7) ÷ 2 = 6

Mode

  • The mode is the number that appears most frequently in a data set.
  • There can be more than one mode or no mode at all if no number repeats.
  • Example: For the numbers 2, 3, 3, 5, 7, 10
    Mode = 3 (because it appears twice, more than any other number)

Range

  • The range is the difference between the largest and smallest numbers in a data set.
  • It shows how spread out the numbers are.
  • Example: For the numbers 2, 3, 5, 7, 10
    Range = 10 - 2 = 8

If you'd like, I can also provide examples or help calculate these for your own data!
