This begins with distinguishing between different types of data, primarily qualitative and quantitative. However, the most informative measure is usually the standard deviation, which calculates how far data points typically deviate from the mean.
Misinterpreting correlation as causation is a common error, highlighting the need for rigorous experimental design and statistical verification. Measures of Spread To understand how much variation exists in the data, we rely on measures of spread or dispersion.
