1996 Wage Survey Glossary
- OES Code = This five-digit code identifies occupations as defined
by the Occupational Employment Statistics program.
- OES Title = A short title describing each occupation included
in the OES occupations.
- Total Firms Sampled = The number of firms sampled for this occupation.
- Number of Respondent Firms = This is the number of valid responses
(firms) who submitted wage data included in the statistical analysis for
each occupation.
- Estimated UI Occupational Employment in 1996 = The number of
Unemployment Insurance (UI) covered jobs in this occupation based on
projections with base year 1990. See footnote below.
- Valid Cases = This is the number of employees for which the respondents
submitted data. For example, "First-Line Supervisors"; (OES code
72002) had 20 firms report for 104 employees (valid cases) who were financial
managers. These valid cases are then used to calculate statistics.
- Min (Minimum) = The smallest hourly rate reported for this occupation.
- Max (Maximum) = The largest hourly rate reported for this occupation.
- Mean = A measure of central tendency. The sum of the values of
all observations divided by the number of observations. It is also called
the arithmetic average. If some values are far removed from the others
(outlying) they can substantially influence the mean.
- Median = A measure of central tendency which is not sensitive
to outlying values. It is the value above which and below which half of
the cases fall, the 50th percentile. For example, if there are 5 cases,
the median is the third largest (or smallest) observation. When there
is an even number of observations, the median is the average of the two
'middle' observations.
- 95% CI for Mean = A range of values (confidence interval) that
95% of the time include the (true) population value of the mean.
- 5% Trim = The arithmetic mean calculated when the largest 5%
and the smallest 5% of the cases have been eliminated. This is desirable
when there are cases with values much larger or much smaller than the rest.
Eliminating these cases from the computation of the mean results in a better
estimate of central tendency.
- Adjustment Factor = Adjustment factors were calculated separately
for Sales, Clerical & Service occupations and for Agriculture, Forestry,
Construction and Operator occupations due to the difference in when these
occupations were originally surveyed (1994 and 1995, respectively). For
Sales, Clerical and Service occupations, adjustment factors were determined
by the average percent change in wage record data from second quarter 1993
to second quarter 1995; for Agriculture, Forestry, Construction and Operator
occupations, adjustment factors were determined by the average percent
change in wage record data from second quarter 1994 to second quarter 1995.
The adjustment factors (average percent change in wage record data)
are abbreviated "Avg Wage Rec % Chg" in the occupational wage tables.
