I am looking into a data set of variables and want to draw z-score chart of the variables. I suppose that Zscore is a series we get. Is it possible to have a single valued z score of variables and subsequently graph of the values. I am attaching data set and the graph I want to make put of it. Any suggestions how this has been drawn!
PS: case is drought scenario.
Thanks
As the z-score simply reflects the difference from the mean of any given value, you can thus easily calculate the z-score for any value and plot it accordingly.
However, it might be difficult to find a suitable mean to compare your values to.
Sven Greving I was wondering if can have single value of Zscore to reflect a series of data. Is it as finding ZScore and then taking average of zscore to get polt as shared?
Thanks
You can of course aggregate values (e.g., calculate the group mean) and calculate the corresponding z-value as the difference from the overall mean. Does this answer your question?
