INTRODUCTION. Statistics is a branch of science that deals with the collection, organisation, analysis of data and drawing of inferences from the samples to the whole population.[] This requires a proper design of the study, an appropriate selection of the study sample and choice of a suitable statistical test.
Significance testing has been the favored statistical tool in some experimental social sciences (over 90% of articles in the This Test Statistic Calculator calculates the test statistic of either one population mean, comparing two population means, or one population proportion.
