A low standard deviation indicates that the values tend to be close to the mean of the set while a high standard deviation indicates that the values are spread out over a wider range. While doing your data science or machine learning projects you would often be required to carry out some statistical operations. In our example below we use MODEB2B12 and since 2 students have scored 55 we get the answer as 55.
Variance and Standard Deviation.
You can think out the solution too. PythonPandas for solving grouped mean median mode and standard deviation. A low standard deviation indicates that the values tend to be close to the mean of the set while a high standard deviation indicates that the values are spread out over a wider range. It shows how much variation there is from the average mean.
