New group -> How is the proposed bin size calculated

‎08-23-2018 01:51 AM

Hi community, 

 

To estimate a density function I grouped data together into bins  and plotted the bins on the X-axis and the frequency on the Y-axis. There is theory about how many bins to use to estimate the density function in a good way. 

So when ever I create a new group for this purpose, Power BI proposes a bin size. 
I want to know what this proposed number is based on ? I  was trying to google the answer without luck.

 

Thanks for your interest in helping me 

Regards 

Elijah

Hi @elijah2018,

Based on my research, you could refer to this link to know the rule of the bin size:
