Key Takeaways
- The standard deviation example illustrates common scenarios of deviation in a dataset.
- Standard deviation is the square root of the variance and measures the variation between data points and their mean.
- It is a valuable tool for statisticians, scientists, financial analysts, and others to assess a dataset's volatility and performance trends.
- Standard deviation provides insights into the distance of data points from the mean and facilitates the comparison of different datasets with the same average.
Conclusion
Statistics informs how tightly various data points clustered around the mean in a normally distributed data set. For example, if the data points bunches closely near the mean, the standard deviation will be a small figure. As a result, the bell curve will be steeply shaped and vise-versa.
The more popular statistical measures like mean (average) or median may mislead the user due to extreme data points. Still, standard deviation educates the user about how far the data point lies from the mean. Also, it helps compare two different data sets if the averages are the same for both data sets.
Hence, they present a complete picture where basic means can be misleading.
