Sample size: It is the number of individuals or elements selected from a larger population to conduct a study or research on. 💡 We provide you with the calculation of the sample size or the number of samples you will apply the questionnaire to, in order to collect responses and analyze the results of the research or study. ✔ Why is sample size important? 1. The larger the sample size, the more accurate the results. 2. If it is too small, it may not represent the population well. 3. If it is too large, it may consume time, effort, and cost without significant additional benefit.
