Modus dari data di bawah ini adalah ... cm

[tex]\begin{gathered}\boxed{\begin{array}{c|c|c}\sf Panjang \: Batang \: (cm)& \sf Frekuensi & \sf fx\\\hline 10 - 19 & 11&11 \\\hline 20 - 29&15&26 \\\hline 30 - 39& 22&48\\\hline 40 - 49& 16&64 \\\hline 50 - 59& 20&84\\ \hline 60 - 69&30&114 \\ \hline 70 - 79&8&122\\\hline &n = 122&\end{array}}\end{gathered}[/tex]

Mencari modus

[tex]\begin{aligned}\sf Mo&= \sf tb + \frac{ \frac{n}{2} - fx}{fm} \times p \\&= \sf 59,5 + \frac{ \frac{122}{2} - (114 - 30) }{30} 10 \\&= \sf 59,5 + \frac{61 - 84}{30} \times 10 \\ &= \sf 59,5 + ( - \frac{23}{30} ) \times 10 \\&= \sf 59,5 + ( - \frac{230}{30} ) \\&= \sf 59,5 + ( - 7 ,66) \\ &= \sf \red{51,84} \end{aligned}[/tex]
