University - STANDARD DEVIATION (SD)  Standard deviation measures how spread out the data are around the mean (average). It shows the typical distance of observations from the mean.  WHAT SD TELLS US: โ€ข Small SD โ†’ values are close to the mean. โ€ข Large SD โ†’ values are widely dispersed. โ€ข SD = 0 โ†’ all observations are identical. โ€ข SD is expressed in the same units as the original data. โ€ข SD alone does NOT tell you whether data are normally distributed.  EXAMPLE: Two groups can have the same mean but different SDs.  Group A: Mean = 70, SD = 3.2 โ†’ values are close to 70. Group B: Mean = 70, SD = 12.8 โ†’ values are more widely spread.  COMMON MISCONCEPTIONS: โŒ SD is not the same as the mean. โŒ A larger SD does not mean the mean is larger. โŒ SD does not tell you the shape of the distribution. โŒ SD is not the same as variance.    Variance = SDยฒ  TAKEAWAY: Standard deviation tells you how much the data vary or spread around the mean. It is a key measure of variability in research and data analysis. | Facebook

Intro To Standard Deviation

NumPy the foundation of data science and machine learning in Python. Covers: arrays (1D, 2D, nD), creating arrays (zeros, ones, arange, linspace), indexing & slicing, array attributes (shape, dtype, size), shape manipulation (reshape, transpose, ravel), math operations, aggregations (sum, mean, min, max, std), broadcasting, stacking, joining and linear algebra.
