Answer:
the formula to mode is
L+[(f1-f0)/2f1+f0+f2]×h
here
L= lower limit of the modal class
h= class width
f1=frequency
f0=before frequency
f2=after frequency
the formula to find median
is
L+[(n/2-cf)/f]×h
L=lower limit
h= class width
n= sum of all frequency
cf= cumulative frequency
f=frequency
hope it helps you
