Common Misconceptions

Standard deviation measures the amount of variation or dispersion of a set of values. It calculates the average distance between each data point and the mean value, giving an idea of how spread out the data points are. In a perfectly normal distribution, 68% of data points fall within one standard deviation of the mean. However, in real-world scenarios, data rarely follows a perfect normal distribution.

  • Standard deviation is only relevant for business or finance applications

    • Standard deviation is used to assess the volatility of investments, allowing investors to gauge potential risks and make more informed decisions.
