Deviation From the Mean: What Does It Really Measure? - starpoint
Opportunities and Risks
Deviation from the mean measures how far individual data points deviate from the average value of a dataset. In simpler terms, it calculates the difference between each data point and the mean value. The goal is to identify patterns, trends, and outliers within the data. For instance, imagine a dataset of exam scores with an average score of 80. The deviation from the mean would show how far each student's score deviates from the average, highlighting individual scores that are significantly higher or lower.
