This method is a fairly recent development, but studies comparing results gained from respondents from MTurk to more traditional samples have found that they provide equally reliable and valid answers (as measured by test-retest, alpha etc).
This has translated into early 'proof of principle' tests involving deep sequencing technology for mutations in specific genes associated with in-situ or low volume disease in tumour DNA isolated from such specimens or more traditional blood samples.
And with a five-inch personal-size pie available, in addition to the more traditional nine-inchers, sampling the entire lineup is a tempting possibility.
An additional simulation study confirmed the effectiveness of this model-based strategy over a more traditional simple random sampling strategy with respect to four regression model design criteria.
Tertiles were used, rather than the more traditional quintiles, owing to sample size considerations.
A fixed effects panel data model might be a more traditional approach to reduce sample variation, but we determined that the random intercept model would be more appropriate due to the policy requirement for all public hospitals to submit hand hygiene data, and the presence of time-invariant variables.
The advantage of using sPCA to a more traditional test of independent samples (e.g., a t-test) is that sPCA reduces the large numbers of variables into a smaller set of uncorrelated variables.
It has been argued, however, that internet samples may actually be more representative than traditional samples [ 3].
Clearly, when compared to the more traditional analytical extraction techniques, equilibrium sampling differs in both means and ends.
The results also clearly demonstrated that the proposed sample preparation method is a more rapid, simpler extraction/desorption technique than traditional sample preparation methods.
