Dealing with skewed mean I have a data set of districts, farmland area and fertilizer subsidies issued for those areas. I.e, using made up numbers,

district | area | subsidy | subsidy per area (computed)
abc      |   20 |   500   |         25
cde      |   30 |   750   |         25
fgh      | 0.02 |    15   |        750    &lt;--- looks off


I'm trying to visualise the subsidy per area but in districts that have very small amounts of farming the subsidy per area seems abnormal. The nationwide average is pretty much around 25. So, I can safely say that the subsidy amount is directly related to the area being subsidised, which is to be expected as fertiliser usage is dependent on the area being farmed. My theory is that the exception on small areas is due to there being a minimum subsidy amount irrespective of the land area.

Are there any techniques to deal with the above scenario when visualising data?
As per business statement it is a exceptional scenario when minimum subsidy will be provided. So for displaying common behavior of data you can drop these exceptional values from table. You can use box-plot to visualize spread of data and then remove else, if you are aware with max range in normal scenario you can drop rows having value more than that.
