This is exactly what political pollsters do - they ask a group of people a list of questions and based on their results‚ they draw conclusions about the population as a whole with

For each combination of flake size and tree species‚ three samples of wood material were constructed. For each sample‚ the physical property measured was the tension modulus of elasticity in the direction perpendicular to the alignment of the flakes‚ in pounds per square inch (psi). For these data‚ a two-way ANOVA was run and the partial

analyze nominal level data to describe variables‚ examine relationships among variables‚ and determine differences between groups in distribution-free or non-normally distributed samples. The assumptions of nonparametric statistics are: (1) values from measurement of study variables need not be normally distributed in the sample‚ and (2) the level of measurement of study variables is usually nominal or ordinal. The mode is the only measure of central tendency that can be calculated for nominal data and
