3ER PARCIAL Inferential statistics Sampling * The purpose of sampling is to select a set of elements (sample) from a population that we can use to estimate parameters about the population * The bigger the sampling‚ the more accurate our parameters will be. example: In the experiment of deciding if CEGL girls are smarter that CEGL boys‚ which would be your statistical hypothesis? Hypothesis testing But now‚ you already gathered information about a sample No‚ you will test if your

techniques can be used to 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
