Estimate the mode of the frequency distribution above.
Answer Details
Mode = a + (b−a)(Fm−Fb)2Fm−Fa−Fb ( b − a ) ( F m − F b ) 2 F m − F a − F b = L1+Δ1xcΔ1+Δ2 L 1 + Δ 1 x c Δ 1 + Δ 2 = 10+(20−10)(27−10)2(27)−10−19 10 + ( 20 − 10 ) ( 27 − 10 ) 2 ( 27 ) − 10 − 19 = 10 + 17025 170 25 = 10 + 6.8 = 16.8
