Data

To make data Input Finished

Sum(Σ), Sample size(n)
Mean
Standard Deviation: σ_n, σ_n-1

Calculate the above value Sort ascending
Classification method

Class Apiece

To determine class interval Minimum(m) =
Maximum(M) =
Start value of some interval
=
Size of class interval(W)
=

when M is a boundary point of interval
To determine last interval [M ^≤ ~ ^< M+W)
[M-W ^≤ ~ ^≤ M ]
Frequency Table

Necessary:
sample value[class interval], frequency
Class Mark
Relative frequency
Cumulative frequency
Cumulative relative frequency

Create frequency table

Calculating with coding x_i = c₁x_i^* + c₂, x_i^* = (1/c₁)(x_i - c₂)
( 1/c₁) =
c₂ =
