Question

If L = 10, f₁ = 70, f₀ = 58, f₂ = 42, h = 2, then find the mode by using formula.

Answer 1

Mode = `"L" + [(f_1 - f_0)/(2f_1 - f_0 - f_2)] xx "h"`

= `10 + [(70 - 58)/(2(70) - 58 - 42)] xx 2`

= `10 + [12/(140 - 100)] xx 2`

= `10 + 24/40`

= `10 + 3/5`

= `(50 + 3)/5`

= `53/5`

Mode = `53/5`
