Imagine I've got this pandas DataFrame:
Class Val
0 A 1
1 B 1
2 B 1
3 B 1
4 B 0
And I want to do the mean of the values grouped by Class, BUT having in mind statistical significance of the values so, if B had a lot of Val equal to 1 the result value of the mean of B will overcome the result value of the mean of A because it only has one observation.

Use:
import pandas as pd
df = pd.DataFrame('Class': ['A', 'B', 'B', 'B', 'B'], 'Val': [1, 1, 1, 1, 0])
print(df.groupby('Class').agg(['mean', 'count']))
You will have to expand on how you decide which to use, but this provides you with the basic info you need to do that.
