We have the (rounded) data relating to the weights of a group of 12-year-old male pupils from a school in the province of Genoa. The data is one per line (a line break between one data and another) and use the comma as a decimal separator. See the data at the bottom of this document. We want to analyze them statistically.

I put the data in the third box and push the button. In the first box I get the data with the decimal point instead of the decimal comma.

Now we can use this file:

A = 25 B = 80 intervals = 11 their width = 5
n=85 min=27.3 max=79.3 median=43.4 mean=45.02235294117647  (I round to 45.02)

The data.
