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)

    • "I always saw the "black" church as a racket that preyed on the vulnerability and resources of black women, especially the single and the older black women."That's precisely why there needs to be churches headed and run by black women. After all, black women are the heart and soul of the church. Nor are they the ones taking sexual advantage of the young and vulnerable. How many black women are even running churches?

    • 16a11335121This is a requirement for almost all lenders out there. The real issue is that their turnaround time is very hard to get the funding from the first party to recover their investment. Is this to be passed through a conventional lending source. 154

    • .>>Now if only the Atty General would follow the constitution as he was sworn to do.<<FURTHARMORE…….The Attorney General is just a pussy like the rest of the liberal Demoracts and Republicans that will do anything to stay in office and the job career of being a constant “free-loader” for the power and privilage of doing nothing! All of these policital bastards will do and say anything to stay in office. And, when they are caught up in their own crap, they blame it on somebody else. What gets me is the “Grandstanding” and then they do absolutly nothing…..

    • It’s about time soonmee wrote about this.

    • I had something similar happen to me at a large public university in Pennsylvania. I have intractable epilepsy, and I have always found it difficult to find an academic position because of my disability. In 2008, I was understandably pleased when I was hired as an adjunct professor to teach several large sections of Western Civ. I had decided to “come out” as an epileptic the previous year, and became active in promoting epilepsy awareness. I made the mistake of assuming that the tenure track faculty would be receptive to a discussion of epilepsy and diversity in academe. Unfortunately, I was excoriated for “pushing” my disability “in their face,” and I was terminated shortly thereafter.

    • Hi Colin. I do enjoy searching out images for the blog. And yes, I remember the Kia Ora orange juice cartons, the tubs – ‘vanilla or neapolitan, dear?’ and the omnipresent Maltesers. Thanks for your comments. I appreciate your feedback.
