(1) Data ~
(2) Data 00 Frequency ~ ( ..... hen two or more of the same data are in·
putted)
Data can be specified in tha form of algebraic formula. but parenthesize the
formula ..... hen using "+", "~", "x" or "-:-" instructiOfl.
Ex. (S +4 x 3) ~ Frequency of data 1
(SINS + LN2) x 5 ~ Frequency of data S
In the ~bove example, il the formula is not parenthesized, 5+ and SINS+ are
neglected, and the same results are experienced as in key operation 4 x 3 ~ and
LN2xS~.
