Inferential statistics are procedures for drawing conclusions about a population based on data collected from a sample, whereas descriptive statistics simply allow us to describe a data set.

A parametric test should be used when certain parameter are known (m and s), the distribution is normal, and the data are interval or ratio. A nonparametric test does not require assumptions about the parameters of the population represented by the sample data (m and s are not needed), the underlying distribution is not normal, and the data are most often ordinal or nominal.

A Type I error is an error in which the researcher claims there is a difference when in reality there is no difference between the groups. Thus, this is similar to a false alarmclaiming that something is there when it is not. A Type II error is an error in which the researcher claims there is no difference between the groups being compared, when in reality there is. Thus, the researcher has missed a difference that is actually there.

A one-tailed hypothesis is a directional hypothesis in which the researcher predicts the direction of the expected difference between the groups. A two-tailed hypothesis is a nondirectional hypothesis in which the researcher predicts that the groups being compared differ, but does not predict the direction of the difference.
