Carane nganggo Kalkulator statistik
Apa sing dietung lan kapan nganggo
Nemokake rata-rata (mean), median, modus, jangkauan, varians, simpangan baku lan kuartil kanggo daftar angka.
Carane nganggo, langkah demi langkah
- Tempel utawa ketik angka-angka panjenengan.
- Pilih sampel utawa populasi.
- Waca ringkesan lan data sing wis diurutake.
Tegese saben input
- Angka – Separate with commas, spaces or new lines Starts at 12, 15, 15, 18, 21, 22, 25, 30, 31, 45.
Carane maca asile
- Rata-rata (mean) – The headline answer. In the default example it reads 23.4 (10 values · median 21.5 · mode 15).
- Cacah – Default Conto: 10.
- Jumlah – Default Conto: 234.
- Median – Default Conto: 21.5.
- Mode – Default Conto: 15.
- Minimal – Default Conto: 12.
- Maksimal – Default Conto: 45.
- Jangkauan – Default Conto: 33.
- Simpangan baku (sampel) – Default Conto: 9.8792712.
Rumus
Mean = sum ÷ n. Variance (sample) = Σ(x − mean)² ÷ (n − 1). Standard deviation = √variance. Median is the middle value of the sorted list.
Conto petungan
With the starting entries (Numbers: 12, 15, 15, 18, 21, 22, 25, 30, 31, 45), the calculator shows mean (average) of 23.4, 10 values · median 21.5 · mode 15. It also reports count 10; sum 234; median 21.5; mode 15.
Asumsi lan watesan
- Sample statistics divide by n − 1.
- Outliers affect the mean more than the median.
Kesalahan umum
- Using population formulas kanggo a sample.
- Including blank cathetan.
