Jul 31, 2023 · Usually, a researcher uses a confidence level of 95% or 99% (p-value of 0.05 or 0.01) as general guidelines to decide if you should reject or keep the null. When your p-value is less than or equal to your significance level, you reject the null hypothesis. In other words, smaller p-values are taken as stronger evidence against the null ...
Jul 17, 2018 · This weakness may be partly due to the typically low sample sizes in psychology (see, e.g., Aczel, Palfi, Szaszi, Szollosi, & Dienes, 2015; Kekecs et al., 2016). Hoekstra, Monden, van Ravenzwaaij, and Wagenmakers (2018) , reanalyzing nonsignificant results in medicine, found much stronger evidence for the null hypothesis with samples two or three magnitudes larger than those in our analysis.

Feb 26, 2021 · This is not an exhaustive list, but hopefully it’ll help you to start getting those higher-level marks in psychology. I also include an example write-up at the end to illustrate how to write all of this up! The quality of the evidence. There are different types of study designs in psychology research, but some are of higher quality than others.

Feb 8, 2021 · Publishing null results helps the scientific community by allowing researchers to build on previous studies. The publication of unsuccessful attempts has the potential to save other researchers’ time. Indeed, a new researcher may use a similar study protocol than a previously unpublished null study and risk having their findings go against ...

How do you determine if a null hypothesis is true?
A crucial step in null hypothesis testing is finding the likelihood of the sample result if the null hypothesis were true. This probability is called the p value. A low p value means that the sample result would be unlikely if the null hypothesis were true and leads to the rejection of the null hypothesis. A high p value means that the sample ...
