To calculate the variance and standard deviation from the given data, we will follow these steps:Step 1: Organize the Data We have the sizes of items (xi) and their corresponding frequencies (fi):| Size (xi) | Frequency
Variance vs. standard deviation Thestandard deviationis derived from variance and tells you, on average, how far each value lies from the mean. It’s the square root of variance. Both measures reflectvariabilityin a distribution, but their units differ: ...
