You can also use this technique to select a random subset from a data set. If
your manager wants you to contact every 20th customer, you can select all
the customers where =RAND() is 0.05 or less.
Syntax
=RANDBETWEEN(bottom,top)
Whereas =RAND() returns a random decimal, =RANDBETWEEN generates an in-
teger between two integers.
The RANDBETWEEN function returns a random integer between the numbers
you specify. A new random number is returned every time the worksheet is
calculated. This function takes the following arguments:
bottom
bottom This is the smallest integer RANDBETWEEN can return.
top
top This is the largest integer RANDBETWEEN can return.
To generate random numbers between 50 and 59, inclusive, you use
=RANDBETWEEN(50,59). RANDBETWEEN is easier to use than =RAND to
achieve
random
integers;
with
=RAND,
you
would
have
to
use
=INT(RAND()*10)+50 to generate this same range of data.
Even though RANDBETWEEN generates integers, you can use it to generate
sales prices or even letters. =RANDBETWEEN(5000,9900)/100 generates ran-
dom prices between $50.00 and $99.00.
