Sixty
seems like a
reasonable
number
of
groups,
so
you decide that
each
small
group
will consist
of five
participants.
Recall
is also
useful
to
verify your last entry,
especially
when your
results
do not seem
to make
sense. For instance,
suppose
you
had
performed this
calculation:

Type in a 5 to replace the
6. One
caution
in
replacing
characters-once you type a
new
character over
an
existing character,
the
original is gone forever! You cannot recall
an
expression that
has
been typed
over.
Notice
that
after
you

the

Whenever
you
position
the

an
existing character,
it
will
be
displayed as
a

cursor.

To calculate the
new
number of
groups,
you
must
replace
the
six
with
an
odd
number.
Five seems to make more
sense
than
seven.
Because
you recalled by using the ~
arrow,
the
cursor is
positioned at the end
of
the
display.
Use
the

cursor
one
space to
the

On
second thought,
you
decide that
groups containing
an
odd
number of participants
might
be
more
effective.
