Beyond Binary: Why Null Hypothesis Significance Testing Should No Longer Be the Default for Statistical Analysis and Reporting
Null hypothesis significance testing (NHST) is the default approach to statistical analysis and reporting in marketing and, more broadly, in science. Despite its default role, however, NHST has long been criticized by both statisticians and applied researchers, including those within marketing.
The most prominent criticisms relate to NHST’s dichotomization categorization of results as “statistically significant” versus “statistically nonsignificant.” This binary treatment of results, using p-values or otherwise, loses information, can be misleading, and prevents meta-analyses which is what science is really all about!
In a new article published in The Journal of Marketing, my colleagues Blakeley B. McShane, John G. Lynch, Jr., Robert Meyer, and I propose a fundamental shift in statistical analysis and reporting in marketing and beyond. In fact, we propose abandoning NHST as the default approach altogether as statistical (non)significance should never be used as a basis to draw conclusions, or as a filter to select what data to prioritize when making decisions.
Beyond Big Data: The Indispensable Role Qualitative Research Plays in Marketing Strategy
In an era where companies are inundated with data, investing billions annually in analytics and technology, understanding the “why” behind customer behavior has never been more important.
From initial consideration to point-of-sale and post-purchase reactions, brands have more data on the customer journey than ever before. This has led many marketing and product leaders to incorrectly believe that they no longer need to invest in primary, qualitative research given the plethora of CRM, transactional, and other data already available to them. This couldn’t be further from the truth.
In this blog post, we discuss the indispensable role that qualitative research plays as a stand-alone methodology or part of a powerful qual/quant combo in better-predicting customer behavior and shaping marketing strategy.
