Regarding the weighted average calculation

jacob
Hello,

I've the medical dataset and I've divided the datasets in to different class
according to the requirement. For example 1) diabetes 2) pneumonia 3) flu
and 4) measles. The datasets have the names of the patients. For example.
for diabates the person name is x, y and z .

1) When calculating the accuracy from the classifier,  the classifier is
predicting the weighted average of 93.5%.

‚Äč2) Similarly, for  pneumonia the accuracy of classifier is predicting the
weighted average of 93.5%.

3) For flu the accuracy of classifier is predicting the weighted average of
94.5%.

4) For measles accuracy of the classifier is predicting the weighted average
of 94.5%.

So i need to calculate the OVERALL WEIGHTED AVERAGE OF ACCURACY OF " MEDICAL
DATASET". In simple mathematical terms it will be 91.5 + 93.5 + 94.5 +
90.5/4  = 370/4 = 92.5%. Is this is a correct method to find the overall
weighted average.

Regards
Ashish
