When entering subject information, you can specify the population
group of the subject. (Refer to the section on
Entering or Selecting
Subject Information
). There are a number of population groups to
select from. These population groups have an associated predicted
normal set and correction factor. These normal sets are usually based
on sex, age and height and are useful when comparing a subject’s test
results with predicted normal values from a suitable reference
population. There is considerable variation in the predicted figures, and
most researchers have an individual preference for a particular normal
set. It is possible to create custom population groups with associated
normal sets and correction factors and save to the database. You can
also delete existing population groups from the database.
To access the Population Group screen:
1. Press the
Options
button on the Home screen.
2. Press the
Population
button on the Options screen.
To modify the Normal set and Correction factor for an existing
Population:
1. Highlight the population group in the population group list box.
2. Select an alternative normal set from the normal set drop-down list.
3. Enter the correction factor in the correction factor field using the on-
screen keyboard. Valid values are between 50–150.
4. You can now do one of three things:
