Standard Deviation Definition

The positive square root of average squared distance of the population or sample values from the mean. It is the most widely accepted measure of dispersion.

Standard deviation in market research is a statistical measure that indicates the amount of variability or dispersion in a set of data points. It quantifies how much individual data points differ from the mean (average) of the dataset. A higher standard deviation indicates greater variability, while a lower standard deviation suggests that the data points are closely clustered around the mean.

Who relies on standard deviation in market research?

Market researchers, analysts and statisticians heavily rely on standard deviation in market research. It is used to assess the spread or consistency of data, identify trends and measure the risk associated with certain outcomes. Businesses use it to understand the variability in consumer preferences, perceptions and behaviors, aiding in strategic decision-making.

Why should I care about standard deviation in market research?

Understanding standard deviation is important because it provides insights into the stability and reliability of your data. A higher standard deviation suggests that the data points are more scattered, indicating potential volatility in consumer behaviors. A lower standard deviation indicates more consistency. This knowledge helps you make informed decisions, manage risks and tailor marketing strategies to different customer segments.
