Skewness
Skewness is a way to measure if data is balanced or leans more to one side, like understanding if sales numbers tend to be mostly high with a few low ones, or vice versa. Think of it like analyzing whether a bell curve is perfectly centered or tilts to one side. Analysts use this to better understand patterns in business data, which helps companies make better decisions. For example, it can help understand customer spending patterns, market trends, or risk assessment. When you see this term on a resume, it usually means the person knows how to analyze data distributions and can provide insights about whether unusual values in data are normal or need attention.
