What's the Difference Between Range and Standard Deviation? - em
Understanding the difference between range and standard deviation can have practical implications in various fields. For instance, in finance, recognizing the limitations of range can help investors make more informed decisions about portfolio risk. Conversely, misusing standard deviation can lead to overestimation of risk, resulting in suboptimal investment choices.
While standard deviation is generally a more comprehensive measure, range can still be useful in certain situations, such as when dealing with small datasets.

How it works (beginner friendly)
The range is a straightforward measure of the spread of data. It's calculated by subtracting the smallest value from the largest value in a dataset. The range is expressed in the same units as the data and provides a simple indication of the variability in a dataset.
Standard deviation is always a more precise measure than range
For instance, if we have a dataset of exam scores with a mean of 70 and a standard deviation of 5, it means that most scores are between 65 and 75 (mean ± standard deviation).
Understanding the difference between range and standard deviation is crucial for anyone working with data, including:
