Mode =36.8Lets take assumed mean, A as 30
Class interval =10
∴ui=xi−Ah=xi−3010
¯x=A+h∑fiui∑fi=30+10×4380
=30+5.375=35.375≈35.37
Hence, Mode =36.8 years, Mean =35.37 years.
Maximum number of patients admitted in the hospital are of age group 36.8 years, while on an average the age of a patient admitted to the hospital is 35.37 years.
