So, so, I can get a range from the top and this is say the attribute on the robot column by the difference or I can also do something is arranged and these are the time this is the attribute variable column and then this one is remove all those are na all those are missing values. So, you can say ah, remove all those na to be true. And then by the difference, so I can do something like this. So let's say I want to find a range of data sample and so I can do something that is raesha data. Okay, so data is here.

Then SEPA land okay should be 4.3 7.9. So to find a difference, I can do something that is different than our range data SEPA land Sorry, I get racial issues around 3.6. So, explanation will be 7.9 minus 4.3, which is three points.
