Performing a parametric statistical analysis requires the justification of a number
of necessary assumptions. If assumptions are not justified research findings are
inaccurate and in question. What happens when assumptions are not or cannot
be addressed? When a certain statistic has no known sampling distribution what
can a researcher do for statistical inference? Options are available for answering
these questions and conducting valid research. This paper provides various
numerical approximation techniques that can be used to analyze data and make
inferences about populations from samples. The application of confidence
intervals to inferential statistics is addressed. The analysis of data that is
parametric as well as nonparametric is discussed. Bootstrapping analysis for
inferential statistics is shown with the application of the Index Function and the
use of macros and the Data Analysis Toolpak on the EXCEL spreadsheet. A
variety of interesting observations are described.
