Does descriptive statistics means parametric statistics?
No.
Descriptive statistics are those that characterise samples
without attempting to draw conclusions. The purpose of them is to
help investigators to form an understanding of what the data might
be capable of telling them. Descriptive statistics include graphs
as well as measures of location, scale, correlation, and so on.
Parametric statistics are those that are based on probabilistic
models (ie, mathematical models involving probability) that involve
parameters. For instance, an investigator might assume that her
results have come from a population that is normally distributed
with a certain mean and standard deviation; this would be a
parametric model. She could estimate this pair of parameters, the
mean and standard deviation, using parametric statistics, or test
hypotheses about them, again using parametric statistics. In either
case the parametric statistics she uses would be based on the
parametric mathematical model she has chosen for her data.
