Abstract
JASP is one of the most user-friendly open-source software programs for data analysis available today, and it has recently also become available online through rollApp. This chapter provides a hands-on introduction to quantitative data analysis using this web-based version of JASP and will guide readers through a few traditional statistical analyses (i.e., a Pearson’s r correlation and a t-test) that are commonly used within applied linguistics. Real studies from the field that have used JASP for their data analyses will also be discussed, after which the challenges that are associated with (online) data analysis and statistics will be considered. We will cover a few points on research ethics and research integrity, as both of these have come under greater scrutiny in the past few years and thus have grown in importance. The chapter will conclude by exploring potential avenues for the future.
