5. Define the data in a set named HI through H5.
On the left side, specify which column of data to
analyze (Cl through C9, CO). (This specification can be
an expression, such as Cl +C2.)
On the right side, specify which column (if any)
represents the frequencies for the values in the left-hand
data column. If there is no frequency data column, then
the frequency for each data value is 1.

6. You can define up to five data sets (HI through H5).
7. Checkmark the data sets you want to analyze. Those data
sets with checkmarks will be computed and plotted
simultaneously. However, only one histogram can be
plotted at a time.
To compute 1. Press | num| {{stats}} to display the results of the
IVAR statistics computed statistics for the current (checkmarked) data
set. These values are defined in the table, "One-Variable
Computed Statistics," on page 5-16.
2, Press {{ok}} when done.
Example; A manufacturing company purchases a certain part four times
Weighted a year. Enter the purchasing data shown below as one-
IVAR Statistics variable sample data (price per part) with frequencies
(number of parts). Find the weighted mean, that is, the mean
price weighted for the quantity purchased.
