Calculation of Mean Using the Data - JSS1 Mathematics Lesson Note
Mean: The mean, also known as the average, is calculated by summing up all values in a dataset and dividing by the number of values. For example, in {3, 5, 5, 7, 8, 8, 8, 10}, the mean is calculated as follows:
Mean=3+5+5+7+8+8+8+10/8=54/8=6.75
