Question

Berikut tabel frekuensi nilai ulangan mtk.
Hitunglah k1,median,dan rata2....!

Answer 1

K1 = 1/4 n
= 1/4 (60)
= 15
K1= b+ l ( 1/4(n) - F
-----------
f
K1 = 25.5 + 10 (60 -7)
-------
14
K1 = 63.35

median = b + l (2/4 n - F)
---------
f
me = 35.5 + 10 ( 30 - 21)
--------
22
me = 39.59

rata-rata= €fi.xi/ €f
rta* = 2340 / 60
rta* = 39
