On the misinterpretation of P>.05 in psychological research
In psychological research, scientists often calculate ‘p-values’ to determine whether their hypotheses can be supported. P-values provide an insight into whether we can expect identified relations in a sample, for instance, whether men and women differ in how much self-control they have, or whether age is a predictor of wellbeing, are likely to also manifest or exist similarly in the broader population of interest who can’t be directly measured because it would be unfeasible to do so.

Two Key Drawbacks of Writing Your Academic Manuscript With R Markdown
A decade ago it was revealed that research practices in psychology were often suboptimal for producing high quality evidence (Nosek et al. 2016). Researchers frequently ran studies with low statistical power (Schmidt and Oh 2016), and engaged in questionable research practices that ultimately rendered p values useless for appraising an effects presence (Schmidt and Oh 2016).

Experience Sampling Data-Wrangling
Experience sampling (ESM) is a popular method used in psychological research because it better enables the testing of hypotheses in real-world environments (Conner et al. 2009). While the flexibility of R is ideal for cleaning and analyzing ESM data, it takes time to figure out the packages, functions, and code needed to achieve these ends.
