Mode = L1 + (\(\frac{D_1}{D_1 + D_2}\))C D1 = frequency of modal class - frequency of the class before it D1 = 5 - 2 = 3 D2 = frequency of modal class - frequency of the class that offers it D2 = 5 - 3 = 2 L1 = lower class boundary of the modal class L1 = 5 - 5 C is the class width = 8 - 5.5 = 3 Mode = L1 + (\(\frac{D_1}{D_1 + D_2}\))C = 5.5 + \(\frac{3}{2 + 3}\)C = 5.5 + \(\frac{3}{5}\) x 3 = 5.5 + \(\frac{9}{5}\) = 5.5 + 1.8 = 7.3 \(\approx\) = 7
