Have you taken a statistics course? Don’t wait too long if you are procrastinating. Mastering that material helps with other classes and in life.
One of the key concepts within statistics is measures of central tendency: mean, median, and mode. Each one tells us about how the data, for one variable or concept, cluster together although each are calculated differently.
The mean is the numerical average. You’ve probably already been calculating means —also known as averages. Add up however many scores or values in your data and divide by how many you have.
