Understanding the methodology is of utmost importance to ensure that plausible assumptions are used in the sample size calculation. Hypothesis Testing Calculation of sample size and/or study power requires precise specification of the statistical hypothesis to be tested. In the hypothesis testing ...

Purpose: The main purpose of this paper is to develop a methodology to analyze the competitiveness based on the diamond model and constructing a composite index; the secondary aim is to apply this methodology to the national index of Turkey's defense industry. Design/methodology/approach: Instead...
All of the approaches mentioned above assume balanced treatment allocation by centre. Randomisation techniques such as block randomisation do not guarantee equal group sizes in all centres, especially if centres are small and block lengths are large. The normal approximation in (1) gives a lower bou...

In quantitative research, when we take a sample from a study population or eligible population in order to save our resources, there are two important statistical processes namely using a probability sampling method (commonly known as “random sampling”) [1], and calculating an appropriate sample...
In systematic reviews and meta-analysis, researchers often pool the results of the sample mean and standard deviation from a set of similar clinical trials. A number of the trials, however, reported the study using the median, the minimum and maximum val
All of these techniques have their own limitations, i.e., the size cutoff is not fine enough to capture the finest droplets (Behbehani et al., 2020). We have designed a simplified and safe sample collection approach for assessing the level of SARS-CoV-2 in the aerosol. This sampling ...
Propensity score matching is a statistical method that is often used to make inferences on the treatment effects in observational studies. In recent years, there has been widespread use of the technique in the cardiothoracic surgery literature to evaluat
Current digestion methods in wastewater research The quality of an analytical methodology resides in the reliability of each step: from sampling, to organic and inorganic matter removal, and quantitative and qualitative MP identification techniques. Establishing the optimal digestion method for an applicatio...
