Rumus Statistika Matematika

Rumus Web mengumpulkan materi Rumus Statistika Matematika ini untuk anak SMA demi UAN SNMPTN SPMB SIMAK UI. Silakan dipelajari :)

Pelajaran Statistika di tingkat SMA meliputi mean, modus, median, jangkauan, simpangan, dan ragam

1. Rumus Rataan Hitung (Mean)
Rata-rata hitung dihitung dengan cara membagi jumlah nilai data dengan banyaknya data. Rata-rata hitung bisa juga disebut mean.

a) Rumus Rataan Hitung dari Data Tunggal

b) Rumus Rataan Hitung Untuk Data yang Disajikan Dalam Distribusi Frekuensi


Dengan : fixi = frekuensi untuk nilai xi yang bersesuaian
xi = data ke-i

c) Rumus Rataan Hitung Gabungan

2. Rumus Modus

a. Data yang belum dikelompokkan

Modus dari data yang belum dikelompokkan adalah ukuran yang memiliki frekuensi tertinggi. Modus dilambangkan mo.
b. Data yang telah dikelompokkan

Rumus Modus dari data yang telah dikelompokkan dihitung dengan rumus:


Dengan : Mo = Modus
L = Tepi bawah kelas yang memiliki frekuensi tertinggi (kelas modus) i = Interval kelas
b1 = Frekuensi kelas modus dikurangi frekuensi kelas interval terdekat sebelumnya
b2 = frekuensi kelas modus dikurangi frekuensi kelas interval terdekat sesudahnya

3. Rumus Median (Nilai Tengah)

a) Data yang belum dikelompokkan

Untuk mencari median, data harus dikelompokan terlebih dahulu dari yang terkecil sampai yang terbesar.

b) Data yang Dikelompokkan


Dengan : Qj = Kuartil ke-j
j = 1, 2, 3
i = Interval kelas
Lj = Tepi bawah kelas Qj
fk = Frekuensi kumulatif sebelum kelas Qj
f = Frekuensi kelas Qj
n = Banyak data

4. Rumus Jangkauan ( J )

Selisih antara nilai data terbesar dengan nilai data terkecil.

5. Rumus Simpangan Quartil (Qd)

6. Rumus Simpangan baku ( S )

7. Rumus Simpangan rata – rata (SR)

8. Rumus Ragam (R)
