Statistical versus Practical Significance

Statistical and Practical Significance of Articles at Sports Biomechanics Conferences

Background. The importance of using statistical approaches has increased and became necessary for researchers and specialists in sports biomechanics because they need more objective and accurate methods to increase knowledge. Objectives. Evaluate the reality of using practical significance in the articles published in scientific conferences in the biomechanical sport. Methods. One hundred twe...

Précis of statistical significance: rationale, validity, and utility.

The null-hypothesis significance-test procedure (NHSTP) is defended in the context of the theory-corroboration experiment, as well as the following contrasts: (a) substantive hypotheses versus statistical hypotheses, (b) theory corroboration versus statistical hypothesis testing, (c) theoretical inference versus statistical decision, (d) experiments versus nonexperimental studies, and (e) theor...

The Role of Statistical Significance Testing In Educational Research

The research methodology literature in recent years has included a full frontal assault on statistical significance testing. The purpose of this paper is to promote the position that, while significance testing as the sole basis for result interpretation is a fundamentally flawed practice, significance tests can be useful as one of several elements in a comprehensive interpretation of data. Spe...

Statistical and practical significance of empirical software engineering research: A maturity model

Context: Software engineering research is maturing and papers increasingly support their arguments with empirical data from a multitude of sources, using statistical tests to judge if and to what degree empirical evidence supports their hypotheses. Objective: This paper presents trends and current state of art regarding statistical maturity in empirical software engineering research; the object...
