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!
