(17) STATISTIK – STATISTICS I, II, III






MODE DATA TAK TERKUMPUL – Mode of a ungrounded
Mode  = Nilai data yang mempunyai frikuensi paling tinggi (the value of data with the highest frequency)
MEDIAN DATA TAK TERKUMPUL – Median of a ungrounded data
Median  =  Nilai di tengah-tengah apabila set data dikumpul dalam susunan menaik (the middle value when a set of data is  arranged in ascending order)
MIN DATA TAK TERKUMPUL – Mean  of a ungrounded data | formula |

UKURAN SERAKAN ~  JARAK , KUARTIL BAWAH (PERTAMA) (Q1),  KUARTIL ATAS (KETIGA) (Q3), INTERKUARTIL (tengah/median)  

            Measure of Dispersion  ~  range,  first / lower quartile  (Q1),  third / upper quartile (Q3),   interquartile rang

·  JARAK (range) = (  terbesar - terkecil ) nilai data



·   Q1  =  Nilai tengah antara nilai awal dan median(the value that divides the values of data that are less than median into 2 equal parts)

·   Q3  =  Nilai tengah antara nilai akhir dan median (the value that divides the values of data that are greater than median into 2 equal parts)

·   Jarak Interkuartil (Interquatile range) = Q3  -  Q1

PENYELESAIAN MASALAH – Solve problem involving ungorounded data
