(5) Sx: Standard deviation with population parameter taken to be "n— 1".
_ / 2 x2 — r\x2 (Used to estimate the standard deviation of population from the
y / n — 1 sample data extracted from that population.)
(6) ox: Standard deviation with population parameter taken to be "n".
ox _ 'Ex2 ~ n* 2 (Used when all populations are taken to be sample data or when
y n finding the standard deviation of population with sample taken
to be a population.)
Data for one-variable statistic calculations are inputted by the following operations
(1) Data [Data]
(2) Data l X I Frequency iPatal (when two or more of the same data are inputted)
Data can be specified in the form of algebraic formula, but parenthesize the formula when using "+", "
"x " or "-r" instruction.
Ex. (5 + 4x3) l Data l
(SINA+ LN2) x 5 S
Frequency of data 1
Frequency of data 5
