What does it mean when a nucleus is stable?
What does it mean when a nucleus is stable? Definition. Nuclear stability means that the nucleus of an element is stable and thus it does not decay spontaneously emitting any kind of radioactivity. Those nuclei with the highest binding energy per nucleon are the most stable with respect to destructive nuclear reactions. What is the […]
Why is Nhst bad?
Why is Nhst bad? NHST is unsuitable for large datasets Most NHST studies rely on nil null hypothesis testing (Nickerson, 2000) which means that H0 expects a true mean difference of exactly zero between conditions with some variation around this true zero mean. The p-value is smaller if the test statistic is larger. Why is […]
What are the benefits of subject design?
What are the benefits of subject design? The main advantage that the within subject design has over the between subject design is that it requires fewer participants, making the process much more streamlined and less resource heavy. For example, if you want to test four conditions, using four groups of 30 participants is unwieldy and […]
