Therefore, 800 respondents are taken as the optimal sample size for the investigation. Therefore using the literature and thumb rule method and results of power analysis indicate that the total sample size needed for the study is around n = 750. I Id like to know how I can utilize the GPOWER Calculator to figure out the sample size for my. Power analysis clearly indicates that to achieve, power of 0.80, a total sample size of n = 725 is needed for this study. Fortunately, power analysis can find the answer for you. Figure 1 gives the power curve for different values of power ranging from 0.5 to 0.95. Using these settings, power curve was extracted. Software ini memiliki kemampuan untuk menghitung berbagai jenis tes statistik termasuk uji-t, uji-f, dan uji chi-square, antara lain sebagainya. For the measurement model each proposed latent construct has four indicators and the number of predictors is taken as 7. GPower merupakan perangkat lunak yang bisa digunakan untuk menghitung kekuatan statistik dan software ini bebas tanpa berbayar. Effect size was kept at small range value of 0.02. Level of significance was kept at α = 0.05. The required power was set at 1- β = 0.80. GPower software application is used to perform a priori power analysis for the study taking multiple regression analysis for the validation of the measurement model. This power analysis is conducted to assess the minimum sample size requirement. In this poster, we will focus on power analysis to get suitable sample size for our research. There are two way to determine the sample size which are from literature review and from the pilot study. Recently, the estimation of the sample size is very important topic for the researchers, so it is an indispensable process for obtaining good results. In: The 9th Saudi Students Conference,, University of Birmingham.įull text not available in this repository. Using GPower software to determine the sample size from the pilot study.
