Accordingly, we tested the intervention in a sample representative of those who would ultimately participate. Randomized controlled trials are not the only standard of research practice for educational and community-based research,70-73 and before-and-after designs are often considered adequate for ...

Control of the Kaiser-Meyer-Olkin (KMO) coefficient, which is an indicator of the adequacy of the sample size for conducting EFA. Kaiser (1974) believes that when KMO is greater than 0.6, factor analysis can be performed with confidence. Values above 0.9 are excellent, values in the range ...

many countries have considered administering PISA to a state-wide representative sample to benchmark theirstudent performanceagainst students from countries around the world. This also occurs in Shanghai – the only city in theMainland Chinato take part in the PISA assessments. The impact of internat...
A priori power analysis was conducted using G*Power version 3.1.9.6 software to estimate the sample size needed to test hypotheses. Results showed that 88 participants (44 for each group) were required to achieve a statistical power of 95% for a two-tailed independent t-test, with a 0.05 ...
JB is the chief investigator; she conceived the study and led the proposal. IS and JB designed the intervention approach and IS trained the service teams to deliver it. BC is the lead statistician and methodologist. SL manages the project. CP-C, ZF, MF, ASh and MS collected and entered...
project was Sample Attrition and patterns of missingness across variables reduced the complete case analytical sample from 15,645 participants to 1583 (Fig.3). Due to attrition, a substantial number of participants originally included in ALSPAC did not have genetic data or linkage to the National ...
The idea behind the focus group is to examine some characteristics or behaviors of a sample when it’s difficult to examine all groups. Table 9 and Fig. 9 show the various evaluation methods used by the articles. Most articles (13; 36.11%) used an experiment to establish the validity of ...
