Conclusion
The standard deviation, on the other hand, measures the amount of variation or dispersion in a dataset. It's calculated by finding the square root of the variance, which is the average of the squared differences from the mean. For the same dataset, the standard deviation would be √((2-6)^2 + (4-6)^2 + (6-6)^2 + (8-6)^2 + (10-6)^2) / 5 = 2.83.

Myth: Standard deviation is only important for large datasets.
Calculating mean and standard deviation may seem daunting, but it's actually a straightforward process. The mean, also known as the average, is calculated by adding up all the values in a dataset and dividing by the number of values. For example, if you have the following dataset: 2, 4, 6, 8, 10, the mean would be (2 + 4 + 6 + 8 + 10) / 5 = 6.
