We'll walk you through the calculation of variance step-by-step, making it easy to grasp how to apply this measure in real-world scenarios. Whether you’re analyzing test scores, investment returns, or any other dataset, variance provides valuable information about the consistency or variability of the data.

Additionally, we will discuss the relationship between variance and standard deviation, another important statistical measure. Understanding this relationship can help you make more informed decisions based on your data analysis.
