GLOSSARY for the 1995 Wage Survey

OES CODE - This five-digit code identifies a particular occupation on the list of Occupational Employment Statistics (OES) occupations.

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 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, 1st line supervisors (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 for this occupation.

MAX (MAXIMUM)- The largest hourly rate 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 2 'middle' observations.

95% CI FOR MEAN - A range of values 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 smaller or larger than the rest. Eliminating these cases from the computation of the mean results in a better estimate of central tendency.
