Kalkulator deviasi standar untuk menghitung ukuran umum dari penyebaran kumpulan data, itu adalah analisis data. Kalkulator dapat memberi Anda nomor input, rata-rata, deviasi standar (SD), deviasi standar populasi (PSD), Varians (SD), Varians (PSD) dari nilai input data yang diberikan.

Berarti Formula.

Mean Formula & Calculation

Misalnya, ketika diberi set data 5,20,40,80,100 , hasilnya akan:

Total input (n) = (5,20,40,80,100)

Total input (n) = 5

Rata-rata (xm) = (x1 + x2 + x3 ... xn) / n

Berarti (xm) = 245/5

Berarti (xm) = 49

-------------------------------------------

Sd =

SQRT (1 / (N-1) * ((x1-xm) ^ 2 + (x2-xm) ^ 2 + .. + (xn-xm) ^ 2))

= SQRT (1 / (5-1) ((5-49) ^ 2 + (20-49) ^ 2 + (40-49) ^ 2 + (80-49) ^ 2 + (100-49) ^ 2 ))

= SQRT (1/4 ((- 44) ^ 2 + (- 29) ^ 2 + (- 9) ^ 2 + (31) ^ 2 + (51)))

= SQRT (1/4 ((1936) + (841) + (81) + (961) + (2601)))

= SQRT (1605)

= 40.0625.

Varians = sd ^ 2

Varians = 40.0625 ^ 2

Varians = 1605.

-------------------------------------------

Psd =

sqrt (1 / (n) * ((x1-xm) ^ 2 + (x2-xm) ^ 2 + .. + (xn-xm) ^ 2))

= SQRT (1 / (5) ((5-49) ^ 2 + (20-49) ^ 2 + (40-49) ^ 2 + (80-49) ^ 2 + (100-49) ^ 2))

= SQRT (1/5 ((- 44) ^ 2 + (- 29) ^ 2 + (- 9) ^ 2 + (31) ^ 2 + (51))

= SQRT (1/5 ((1936) + (841) + (81) + (961) + (2601)))

= SQRT (1284)

= 35.8329.

Varians = sd ^ 2

Varians = 35.8329 ^ 2

Varians = 1284.
