<prompt> The incidence of malaria in an area is 20, 20, 50, 56, 60, 5000, 678, 898, 345, 456. Which of these methods is the best to calculate the average incidence?Arithmetic meanGeometric meanMedianMode  <response>: In the given question, Since extreme values outliers are present for incidence 20 and 5000, median will be the most suitable measure of central tendency. Incidence of malaria in an area is 20, 20, 50, 56, 60, 5000, 678, 898, 345, 456 And, incidence in ascending order is 20, 20, 50, 56, 60, 345, 456, 678, 898, 5000 Mean an 758310 758.3 Median Mean averageof 5th and 6th value 60 3452 202.5 Mode 20 Mean will not be an appropriate measure of central tendency since extreme values outliers are present.
