From December 2022 to January 2023, the Data Literacy Seminars were held by Professor Jorge TENDEIRO, Program Manager of the HIRAKU-Global Program. With the theme of unraveling "common misunderstandings" about statistical methods used in research across various fields, a total of five in-person sessions were held at each university to which the HIRAKU-Global Researchers belong to.

At the beginning of each seminar, quizzes on hypothesis testing and confidence intervals in statistics were given to reaffirm the basic steps of statistics. Prof. TENDEIRO also explained that when statistical tests are used in academic research, they are inferences based on the data at hand and are "indirect" explanations of the theory.

Next, regarding hypothesis testing and confidence intervals, he discussed the misunderstandings of the methods and expressions for presenting results from various angles, referring to the participants' papers and actual simulation results. The revamping policy on statistical representations and practical dilemmas for various internationally renowned main journals was also discussed.

In addition, there was an active discussion on the effective explanation of research results on topics such as errors, symbols and effect sizes in graphs and plots.

Finally, Prof. TENDEIRO concluded, "The content of this training can be put into practice immediately, and some fields may not be so, but through this seminar, you will be able to read many papers containing statistical expressions from a critical perspective." The overall response from the participants was positive, with the opinion that "it gives new perspective for researchers who usually use statistical methods, and it was difficult for researchers who usually don’t use statistical methods, but it was useful because it was something they should know."
