mode is the most occuring observation. so the modal class in this question is 85-95. to find the mode we have to use the formula:
mode= l+[f₁-f₀/2f₁-f₀-f₂]×h
where
l= lower limit of the modal class
f₁=is the frequency of the modal class
f₂=is the frequency of the class succeeding the modal class
f₀= is the frequency of the class preceeding the modal class
h=is the height of the modal class(or size of the modal class)
so,
mode=85+[32-30/2×32-30-6]×10
=85+[2/64-36]×10
=85+[2/28]×10
=85+5/7
=85+0.71
=85.71
∴the mode of the given data is 85.71
mode= l+[f₁-f₀/2f₁-f₀-f₂]×h
where
l= lower limit of the modal class
f₁=is the frequency of the modal class
f₂=is the frequency of the class succeeding the modal class
f₀= is the frequency of the class preceeding the modal class
h=is the height of the modal class(or size of the modal class)
so,
mode=85+[32-30/2×32-30-6]×10
=85+[2/64-36]×10
=85+[2/28]×10
=85+5/7
=85+0.71
=85.71
∴the mode of the given data is 85.71
