In order to address drawbacks of the p-value, Bayesian statistics have been considered as an alternative approach to estimate the probabilities of an effect in TESOL and applied linguistics fields (Loerts et al. 2020; Norouzian et al., 2018, 2019). The workshop consists of two main parts: 1) the introduction of JASP, an open-source software, and the usefulness of Bayesian statistics, and 2) the practice session. The talk will first introduce the current issues of the p-value as well as the usefulness of the Bayes factor. After the speaker explains how to prepare the quantitative data and how to conduct descriptive testing using JASP, he will cover four main types of statistic testing using Bayesian factor: 1) item reliability testing, 2) t-test, 3) ANOVA, and 4) correlation. With the speaker’s support, the audience will also have hands-on experience performing Bayesian statistic testing with sample datasets so that they can perform them with their dataset even after the workshop. At the end of the workshop, the speaker will re-emphasise the necessity of investigations with Bayesian statistical testing in future research in the second language teaching and learning field.
PechaKucha is a storytelling format where the presenter will show 20 slides for 30 seconds of commentary each. We'll share personal presentations about our work and ideas.
