Understanding measures like mean, median, and mode is really important for Year 7 students. These tools help you look at data and make smart choices in everyday life.
Mean:
The mean is what most people call the average. You find it by adding up all the numbers and then dividing by how many numbers there are.
For example, if the test scores are 70, 80, 90, and 100, you would do this:
So, the average score of the class is 85.
Median:
The median is the middle number when you put all the numbers in order. It's great for understanding how the data is spread out, especially when there are some really high or low numbers, called outliers.
For our scores of 70, 80, 90, and 100, if we put them in order, the median is:
So, the median score is also 85.
Mode:
The mode is the number that shows up the most.
For the scores 70, 80, 80, and 100, the mode is 80. This tells us that 80 is the most common score.
By using these measures, students can better understand different types of data, like sports stats or survey results. This helps build important skills for analyzing information and making good decisions.
