Measures of central tendency are very important in Year 8 math for a few reasons:
Understanding Data: They help us make sense of big groups of numbers by breaking them down into one easy-to-understand value.
Types of Measures:
Mean: This is the average. You find it by adding all the numbers together and then dividing by how many numbers there are. For example, for the numbers 2, 3, and 5, you would do this: (2 + 3 + 5) ÷ 3 = 3.33.
Median: This is the middle number when you put all the numbers in order. For the numbers 1, 3, and 4, the median is 3.
Mode: This is the number that appears the most. In the group 2, 2, and 3, the mode is 2.
Knowing about these measures helps us see patterns in data and make good decisions!
