Relation variance and standard deviation
WebFeb 17, 2024 · The square root of the variance gives you the standard deviation. Like how the mean tells you where the data is centered, the standard deviation gives you the width of your bell curve. It tells you how narrow or wide the bell curve is. Consider the example of income in rural and urban areas. Figure 2: Standard Deviation WebVariance, and its square root standard deviation, measure how “wide” or “spread out” a data distribution is. We begin by using the formula definitions; they are slightly different for …
