 0                         Nilai rata-rata
I. Mean
1. Mean Nilai Matematika
   =              =


    =85+80+75+50+55+55+55+50+50+45
                 10
Maka, mean nilai matematika adalah 67,5
2. Mean Nilai IPA
     =               =

     =                             =

Maka, mean nilai IPA adalah 62,5
3. Mean Nilai Rata-rata MIPA
    =                 =

     = 75+72,5+65+65+62,5+62,5+57,5+55+50+47,5 =
                        10


Maka, mean nilai rata-rata MIPA adalah 61,25
II. Modus
1. Modus Nilai Matematika
   Untuk mempermudah mencari modus, kita
   buat tabel seperti berikut ini:
      n    85   80    75   55    50   45
      F     1    1    1     3    3     1

   Disini, dapat kita lihat bahwa modusnya
   adalah 55 dan 50
2. Modus Nilai IPA

  n    80   70    65   60   55   50
  F    1     2    2    2    1    2

Nah, disini terlihat bahwa modusnya
adalah 70,65,60,dan 50
3. Modus Nilai Rata-Rata MIPA
  n   75 72,5 65 62,5 57,5 55   50 47,5
  F   1   1   2   2    1   1    1   1


  Modusnya adalah 65 dan 62,5
III. Median
1. Median Nilai Matematika

  85; 80; 75; 55; 55; 55; 50; 50; 50; 45

  Karena banyaknya datum 10 (genap)
  maka median=
2. Median Nilai IPA
  80; 70; 70; 65; 65; 60; 60; 55; 50; 50

  Mediannya=
3. Median Nilai Rata-Rata MIPA
  75; 72,5; 65; 65; 62,5; 62,5; 57,5; 55; 50; 47,5

  Median=
IV. Jangkauan
1. Jangkauan Nilai Matematika
    85; 80; 75; 55; 55; 55; 50; 50; 50; 45

   Jangkauan nya adalah datum
   terbesar-datum terkecil= 85-45 =50
2. Jangkauan Nilai IPA
   80; 70; 70; 65; 65; 60; 60; 55; 50; 50

   Jangkauannya=80-50=30
3. Jangkauan Nilai Rata-Rata MIPA
    75; 72,5; 65; 65; 62,5; 62,5; 57,5; 55; 50;
    47,5
   Jangkauan = 75-47,5 = 27,5
V. Kuartil dan Jangkauan Kuartil

1. Kuartil dan Jangkauan Kuartil Nilai Matematika
   85; 80; 75; 55; 55; 55; 50; 50; 50; 45

       Q3            Q2            Q1
   Karena genap, maka Q2=(55+55)/2=55
   Dan karena genap Q1 dan Q2 dihitung dari 85-
   55 dan 55-45, diperoleh lah Q3=75 dan Q1= 50
   Jangkauan kuartilnya berarti kuartil atas-kuartil
   bawah=75-50=25
2. Kuartil dan Jangkauan Kuartil Nilai IPA
   80; 70; 70; 65; 65; 60; 60; 55; 50; 50

        Q3          Q2            Q1
   Q3=70
   Q2=(65+60)/2=62,5
   Q1=55
   Jangkauan kuartil=Q3-Q1
                    =70-55
                    =15
3. Kuartil dan Jangkauan Kuartil Nilai Rata-Rata
   MIPA
   75; 72,5; 65; 65; 62,5; 62,5; 57,5; 55; 50;
   47,5

             Q3           Q2          Q1
   Q3=65
   Q2=(62,5+62,5)/2=62,5
   Q1=55
   Jangkauan kuartil=Q3-Q1
                     =65-55
                     =10
Terimakasih
