Choose a sampling method:Different methods can be used depending on the study's objectives. For example, random sampling focuses on fairness, whereas systematic sampling uses regular intervals. Determine the sample size:Thesample sizeneeds to be manageable and large enough to provide reliable results....
Therefore, this kind of sampling method is inadvisable when used for a representative study. The online survey with snowball sampling is, of course, not able to deliver representative results. However, it can be easily used when we know the basic population and have online access to its ...
Needle rotation delivered larger biopsy samples than the standard method. Laitinen provided larger samples than the Nashold needle, with the same sampling method or vacuum pressure. A higher histopathological diagnostic quality of tissue was obtained with the Laitinen needle than with Nashold, with ...
A method for measuring the comparability of different sampling methods used in biological surveys: implications for data integration and synthesis Freshwater Biology - Cao, CP, et al. - 2005 () Citation Context ...l. 1992; Lenz and Miller 1996; Muzaffar and Colbos2002; Scarsbrook and ...
This study applies this factor in the context of online learning research, and forms the concept of “continuance intention of online learning,” which is defined as learners’ intentions to continue choosing online learning as the primary learning method. This study seeks to determine whether ...
project on municipal wastewater treatment plants, 500–1000 mL of wastewater was collected by a grab sampling method in high-density polyethylene (HDPE) sterile containers. The specimens were transferred to the laboratory on ice and kept at 4°C. Then, 200 mL of the sewage was processed by ...
particular major at a particular institution (e.g., all students studying mathematics at the University of Cologne). This sampling strategy resulted in 444 realized clusters, 52 of which consisted only of teacher candidates (Zinn et al.,2017). Students willing to participate were surveyed starting...
In addition, we used the person correlation method; the correlation filter was set to 0.8 and the P-value to 0.05, and agglomeration was performed at the genus level. Statistical analysis of the data To identify the difference in microbial community composition between samples and different ...
Exploring, feeding, playing and tail wagging were observed by instantaneous observation at 20-s intervals and sampled with the one-zero sampling method, and all the occurrences of the above behaviours during observation were recorded. These data were regarded as event behaviours and recorded as ...
*H2SO4 was added until the pH of the irrigation water <6. A timeline presenting the activities that were carried out in the aforementioned course of the experiment is presented in Fig. 2. 2.2. Soil sampling and analyses Throughout the experiment, soil samples were taken from each plot near...
