The phrase "a standard duration" is correct and usable in written English.
It can be used when referring to a typical or expected length of time for an event or process.
Example: "The project is expected to take a standard duration of six months to complete."
Alternatives: "a typical duration" or "an average duration".
Following a standard duration period of enoxaparin treatment (with placebo tablets) or betrixaban (with placebo injections), patients receive only betrixaban (or alternative matching placebo).
Prior to testing, subjects received 30 practice trials with a standard duration of 1000ms.
Subjects were trained to distinguish a standard duration (200 600 1400 msec in different blocks) and asked to judge if it was the same or different to a probe (see Figure 1A).
In summary, the total average cost of a standard duration of treatment with boceprevir is slightly more costly than a standard duration of treatment with telaprevir, and so is the average cost per SVR.
This may seem short for a first consultation; however, this is a standard duration in the Netherlands.
Figure 2 presents the cumulative cost per patient over the treatment course and follow-up for those treated with a standard duration of therapy.
Moreover, previous studies have shown that the coefficient of variation in warned reaction time tasks did not vary as a function of standard duration [9], [40], thus conforming to Weber's law, and that the time between movements in a predictive saccade task demonstrated the scalar property of variance [16].
To explore if subjects had accurate representations of the standard duration, a mixed ANOVA on CE (Table 3) from both tasks (task [TG and TE] as the between subjects factor and standard duration [200 600 1400 msec] as a within subjects factor) was conducted.
Given that temporal variance in Experiment 1 increased as a function of the standard duration (Weber's Law), the ratio between the probe and the expected foreperiod was slightly different for different standard durations, varying on average no more than 10% (for example, the ratio of shortest probe to the expected one ranged from 0.45 at 200 msec to 0.52 at 1400 msec).
The standard duration of a training course at a papa school is six lessons of two hours each.
Since step-sizes were a constant fraction of the standard duration, difficulty of discrimination was the same for the three standard durations given that the eleven probes were approximately the same proportion of the standard.
