I calculated the average score for the Athletics day teams.
To find the average, I added the class scores for each team then divided the total by the number of data points.
I rounded the numbers up when I divided them. When rounding, if the number is four or less, I round down. If the number is 5 or higher then you round upwards.
Knowing how to calculate the average is important because it can help to find out the scores of things without a calculator.
