Sequential testing can be incorporated into null hypothesis significance testing (Kelley et al., Citation2018; Lakens, Citation2014), although it has been criticised for this use because only a limited number of interim tests can be performed (Schnbrodt et al., Citation2017; Wagenmakers, Citation2007) and Kruschke (Citation2013) contends that it will inevitably lead to a 100% false alarm rate (falsely rejecting the null hypothesis). Schabort, and J.A. Some argue that because the confidence interval is a theoretical long-run pre-data procedure with a fixed probability (e.g., 95%), there is no guarantee that a post-data confidence interval will contain the population parameter at all, or have the desired precision (Morey et al., Citation2016). why is precision important in sport research - kaushaldarji.com It's like asking: If I took the measure again, without doing anything that is likely to change the measure (e.g. In this whole process, close attention should be given to specific factors of the study (e.g. It doesn't seem like that big of a deal, you are only missing a tablespoon on the cup. In regard to overestimating population effect size, the Open Science Collaboration (Citation2015) conducted 100 replications of psychology studies using high-powered designs and reported that the mean effect size (r=0.2; ~d =0.4) was approximately half the magnitude of that reported in the original studies.
