Penjelasan dengan langkah-langkah:

Datanya saya masukkan ke tabel yg dmn angka nya sdh saya urutkan

[tex] \: \: \: \: \: \footnotesize \boxed {\begin{array}{c|c|c} \sf{\red{No.}}&\sf{\red{Data}}&\sf{\red{Frekuensi}}\\ \hline \sf{1}&\sf{10}&\sf{1} \\ \hline \sf{2}&\sf{11}&\sf{1} \\ \hline \sf{3}&\sf{12}&\sf{1} \\ \hline \sf{4}&\sf{13}&\sf{1} \\ \hline \sf{5}&\sf{ \red{{14}}}&\sf{1} \\ \hline \sf{6}&\sf{ \red{15}}&\sf{1} \\\hline\sf{7}& \sf{16}&\sf{1} \\\hline \sf{8}&\sf{17}&\sf{1} \\ \hline\sf{9}& \sf{18}&\sf{1}\\ \hline\sf{10}& \sf{20}&\sf{1} \end{array}} \\ \: \: \: \: \sf{Jumlah \: keseluruhan= 10 \: (genap)}[/tex]

[tex] \footnotesize \begin{aligned} \sf{Median} = \dfrac{ (\dfrac{data \: ke - n}{2}) + (\dfrac{data \: ke - n}{2} + 1) }{2} \\ \\ \sf{} = \sf{\dfrac{ (\dfrac{data \: ke - 10}{2}) + (\dfrac{data \: ke - 10}{2} + 1) }{2} } \\ \\ \sf{} = \dfrac{ (\dfrac{data \: ke - 10}{2} )+ (\dfrac{data \: ke - 10}{2} + 1)}{2} \\ \\ \sf{} = \sf{ \dfrac{ data \: ke - 5 + data \: ke - 5 + 1}{2} } \\ \\ \sf{ \dfrac{data \: ke - 5 + data \: ke - 6}{2} } \\ \\ \sf{} = \sf{ \dfrac{14 + 15}{2} }\\ \\ \sf{} = \sf{ \dfrac{29}{2} } \: \: \: \: \: \: \: \\ \\ \sf{} = \underline{ \boxed{ \red{ \bf{14,5}}}}\end{aligned}[/tex]
