Determining an appropriate sample size is vital in drawing realistic conclusions from research findings. Although there are several widely adopted rules of thumb to calculate sample size, researchers ...remain unclear about which one to consider when determining sample size in their respective studies. ‘How large should the sample be?’ is one the most frequently asked questions in survey research. The objective of this editorial is three-fold. First, we discuss the factors that influence sample size decisions. Second, we review existing rules of thumb related to the calculation of sample size. Third, we present the guidelines to perform power analysis using the G*Power programme. There is, however, a caveat: we urge researchers not to blindly follow these rules. Such rules or guidelines should be understood in their specific contexts and under the conditions in which they were prescribed. We hope that this editorial does not only provide researchers a fundamental understanding of sample size and its associated issues, but also facilitates their consideration of sample size determination in their own studies.
The article is based on surveys carried out among students of selected technical universities in the West Pomeranian Voivodeship (Poland). It aims to determine students' knowledge of new tools such ...as ChatGPT, the use of which raises a discussion among the scientific community and beyond. According to some groups it can support learning, whereas others claim that it can limit problem-solving skills and creative thinking. Three hundred students of engineering and master's studies participated in the study. The results of the conducted research show the directions of the use of ChatGPT by students and their interest in this tool.
