These forms of activism all play intertwined roles in the movement — when outcomes of interventions are interdependent, the effectiveness of each is inextricably linked with those of the others. Besides, context plays a key role in dictating marginal effectiveness. Justifying one form of advocacy as being more effective than another is not quite straightforward — declaring so is often misleading. Ideally, instead of ranking them on their effectiveness, we must seek insight on how best to distribute our limited resources amongst them. <a href="http://www.humaneleaguelabs.org/blog/2018-01-30-how-ranking-of-advocacy-strategies-can-mislead/">Read more ...</a>http://www.HumaneLeagueLabs.org/blog/2018-01-30-how-ranking-of-advocacy-strategies-can-mislead/The trouble with significance testinghttp://www.HumaneLeagueLabs.org/blog/2016-05-20-the-trouble-with-p-values/You have probably heard of the p value, the ubiquitous quantity that shows up in research articles discussing the statistical significance of observed differences. The drugs we test in medicine and the interventions we evaluate in social sciences are often hawked or dismissed based on the claims of statistical significance or lack thereof as measured by the p value. It is also widely used in animal advocacy research. But, the p value is often not only insufficient to reach clear conclusions but is also prone to incorrect interpretations by scientists and lay persons alike. It is more clarifying and meaningful for researchers to report confidence intervals and, even better, to provide descriptive statistics of all data including frequency distributions of the observed effects. Good statistical practice in research, since at least the 1980s, has recommended these replacements of the p value. For this reason, Humane League Labs will not use or report p values exclusively but only together with confidence intervals and the comprehensive descriptive statistics necessary for robust inferences. <a href="http://www.humaneleaguelabs.org/blog/2016-05-20-the-trouble-with-p-values/">Read more to find out why ...</a>.http://www.HumaneLeagueLabs.org/blog/2016-05-20-the-trouble-with-p-values/
