Data sets with a high mean and a low standard deviation show that the majority of values are tightly grouped around a high central value. Here are few examples:

Test Scores in a Well-Prepared Class: If the majority of students score well, scoring between 90 and 95 percent, the mean is high and the deviation is small.
Salaries in a Specialised Profession: Salaries for professionals with similar experience and expertise, such as tenured professors, may be high with little fluctuation.

Product Weights in Quality-Controlled Manufacturing: When a factory produces things under strict quality control, the product weights can be high (near the target) with minimum variance.
These examples show how data points are densely grouped around a high average value. for free Demo Class Online contact us today at Durga Online Trainer
