Why is Variance Gaining Attention in the US?
At its core, variance measures the spread or dispersion of a dataset. It calculates the average of the squared differences between each data point and the mean. This results in a single value that indicates how much the data deviates from the average. Think of it as a snapshot of the data's distribution, showing how spread out the values are.
