Summary/Abstract: Referring to the current methodological awareness of psychologists, drawing on his own longstanding research and teaching experience, and inspired by works such as Cohen (1990-2006, 1994/2006) or Wilkinson & Task Force on Statistical Inference (1999), the author addresses crucial problems involved in the use of methods of statistical analysis of data derived from psychological research. He also draws attention to the possible sources of misconduct as well as to optimal solutions, whose adoption by researchers will minimize error variance and contribute to a significant reduction of artifacts created. The aim of the article is also to draw attention to the possible sources of scientific misconduct. The author focused on the following the issues: the standard view of the research process, the concept of statistical analysis of data in the research process, the necessity of replicating research findings, the NHST vs. confidence interval opposition, the importance of determining effect size, and the usefulness of conducting multivariate analysis.
