(2) Statistics
• It is possible to input statistical data directly into the list.
• The amount of data allowed for input varies according to the used memory space,
however, up to 999 elements can be entered (per list).
• Statistics obtained from entered statistical data are as follows:
Statistics of 1-variable (x):
n: sample number
: mean of sample (x)
sx: standard deviation of sample (x) (standard deviation when modulus is “n-1”)
sx
σ
x: population standard deviation of sample (x) (standard deviation when modulus is
n)
Σ
x: sum of sample (x)
Σ
x
2
: sum of squares of sample (x)
xmin: smallest value of sample (x)
Q
1
: median of Med and the smallest value
Med: median of sample (x)
Q
3
: median of Med and the largest value
xmax: largest value of sample (x)
Statistics of 2-variable (x, y):
The following statistics are obtained in addition to the statistics of the 1-variable (x).
Σ
xy: sum of product of sample (x,y)
: mean of sample (y)
sy: standard deviation of sample (y) (standard deviation when modulus is (n-1))
σ
y: population standard deviation of sample (y) (standard deviation when modulus is
n)
Σ
y: sum of sample (y)
Σ
y
2
: sum of square of sample (y)
ymin: smallest value of sample (y)
ymax: largest value of sample (y)
• These statistics are obtained by [1_Stats] or [2_Stats] of
C
1
or
2
after inputting statistical data.
