Analysis
Because the present study was descriptive, the statistical analyses
reported in the following sections of the article are straightforward
and consist of crosstabulation of variables, display of distributions,
and calculation of measures of central tendency. Because of
missing data in the Institute records, the analyses involved Kinsey
ns that were smaller than the total n for the Kinsey
census sample. These active ns are specified in the
text and/or tables. No statistical tests of mean differences
were employed between the Kinsey and photo samples since they did
not jointly fulfill all the assumptions of such tests. Differences
that are noted in the text will be those that are most apparent
and compelling to the writer.
We appreciate that group differences in this study could be due
to some combination of the following: (a) greater than average
homosexual and/or naturist (nudist) representation in the photo
sample, (b) a secular trend representing actual physical changes
between the time of the Kinsey data collection and the current day,
(c) more accurate and valid measurement in the photo sample, (d)
some degree of reporting bias in the Kinsey data due to face-to-face
interview reporting and self-measurements. All of these may
be affecting the study, but in our discussion we will attempt to
state what we believe to be the main sources of any observed differences.
