an investigative analysis of the psychological characteristics and job ...

Neuman (2003:183) identifies eight types of validity, namely face validity, content validity, criterion
validity, concurrent validity, predictive validity, construct validity, convergent validity and
discriminant validity. For the purposes of this study, only face and content validity will be discussed.
3.4.5.1 Face Validity
Neuman (2003: 183) is of the opinion that face validity is the easiest to achieve. According
to him and Struwig and Stead (2001 :139), face validity refers to whether the items of the
test appear to measure what the test claims to measure.
The different items contained in the final questionnaire, e.g., role and responsibility,
personality traits, abilities and characteristics, qualifications and experience clearly
comprises the profile of a GEL and therefore the questionnaire measures what it claims to
measure.
3.4.52 Content Validity
According to Struwig and Stead (2001:139), content validity refers to the extent to which
the items reflect the theoretical content domain of the construct being measured.
The content validity of the researcher's measuring instruments was evaluated by a panel
of experts as discussed in 3.4.2.
3.5 DATA CAPTURING AND DATA EDITING
The researcher consulted various sources (Rose & Sullivan, 1993; Fink, 1995; Greenfield, 1996;
Wright 1997 and Byme, 2002) on statistics and data capturing, editing, and analysis. In addition
she consulted a specialist in the field of statistics. This is also recommended by Struwig and Stead
(2001 :150). They mention that data analysis is a specialised area of research procedures and that
the researcher should use experts in the field.
