The experimental data could be collected over five times diluted samples which had an average pH of 7.5.
The quality of a forecast should be evaluated on the basis of both its reliability (agreement with observed data to be collected over many trials) and skill (performance relative to a standard forecast).
The researchers concluded that for decisions regarding tenure and promotion, data should be collected over at least two to four occasions.
Because we used a waterproof wrist-worn accelerometer which allowed data to be collected over 24 hours, we expected a stronger correlation than was obtained in previous studies.
To obtain precise estimates for some measures (e.g., household income) that vary substantially by individual, a large sample size would be needed and information would need to be collected over many years to understand the full economic impact over one's lifetime.
One important distinction of MRI, as compared to TCD and ICP, is that the MRI measurement is not taken in real-time; instead, the image must be collected over many cardiac cycles, so that the resultant velocity waveform is an average measure over many cycles.
Several free software solutions, such as WebExp (Keller, Gunasekharan, Mayo, & Corley, 2009) and MiniJudge (Myers, 2009), have been developed to allow acceptability judgments to be collected over the Web, and thus reduce some of the collection time.
The total amount of fees to be collected over three years is $25 billion.
Another challenge is that the temperature effects can be subtle, meaning data has to be collected over a long period.
We are owed about $200,000, which, God willing, will be collected over the next six weeks; our current debt is more than that.
When the city unveiled the idea in February, a Transportation Department presentation said data on the plazas would be collected over three weeks in May and June, and all of July.
