Inferential statistical tests are more powerful than the descriptive statistical tests like measures of central tendency (mean, mode, median) or measures of dispersion (range, standard deviation). When conducting research, there will always be confounding factors to some degree, in addition to the effects of the independent variable on the dependent variable. This z-score, or standard score, is the signed number of standard deviations by which the data points' value is above the mean value of that which is being measured. ...

Study results will vary from sample to sample strictly due to random chance (i.e., sampling error). A standard type of problem in basic statistics is to calculate the z-score of a value, given that the data is normally distributed and also given the mean and standard deviation. Inferences are steps in reasoning, moving from premises to logical consequences; etymologically, the word infer means to "carry forward". For example, the results of a study may be due to chance and not the independent variables. The inferences are made with parametric and non-parametric tests and multivariate methods.
