Diketahui :

20, 22, 22, 24, 21, 22, 23, 21

Ditanya :

Mean
Median

Jawab :

1.) Mean (rata-rata)

$\tt \blue{= \frac{jumlah \: seluruh \: data}{banyak \: data} }$

$\tt \blue{ = \frac{21 \times 2 + 20 + 22 \times 3 + 23 + 24}{8} }$

$\tt \blue{ = \frac{42 + 20 + 66 +23 + 24 }{8} }$

$\tt \blue{ = \frac{62 + 89 + 24}{8} }$

$\tt \blue{ = \frac{175}{8} }$

${\boxed{ \tt{ \red{ =21,875 }}}}$

2.) Median (nilai tengah setelah data diurutkan)

20 , 21 , 21 , 22 , 22 , 22 , 23 , 24

= (22 + 22)/2
= 44/2
= 22 → median

Mean
Median

Jawab

Data | Jumlah / Frekuensi

20 Muncul 1x

21 Muncul 2x

22 Muncul 3x

23 Muncul 1x

24 Muncul 1x

Mean

$\sf \frac{(20 \times 1) + (21 \times 2) + (22 \times 3) + (23 \times 1) + (24 \times 1)}{8}$

$\sf = \frac{20 + 42+ 66 + 23 + 24}{8}$

$\sf = \frac{175}{8}$

$\sf = \underline{ \red{ 21,875}}$

Median

Data

20, 22, 22, 24, 21, 22, 23, 21

Urutkan dari yang terkecil

20, 21, 21, 22, 22, 22, 23, 24

Cari nilai tengah

20, 21, 21, 22, 22, 22, 23, 24

Kesimpulan

Jadi, nilai tengah dari data tersebut sudah terlihat jelas bahwa median nya 22
