| Goals | It shows how to calculate the appropriate sample size to ensure that the scientific research results are more reliable and more economical. |
| Course Content | Rules and analytical approaches to be taken in deciding the appropriate sample size, which is one of the most important stages of research, will be addressed. For this purpose, we will focus on what should be taken into consideration when determining the appropriate sample size in the most frequently performed research types in practice, and the introduction and application of formulas that can be used in calculating the sample size. The statistical package program or web-based account pages that can be used to calculate sample size will also be examined. |
