Increasing Precision without Altering Treatment Effects: Repeated Measures Designs in Survey Experiments

American Political Science Review, 2021
The use of survey experiments has surged in political science. The most common design is the between-subjects design in which the outcome is only measured posttreatment.

Maximizing precision over extended unambiguous range for TOF range imaging systems [PDF]

, 2010
The maximum unambiguous range for time-of-flight range imaging systems is inversely proportional to the chosen modulation frequency. However, increasing the unambiguous range by decreasing the modulation frequency will generally also degrade the range ...

Plot size and experimental precision for sunflower production

, 2010
In order for sunflower cultivation to be economically sustainable, research should be based upon suitable experimental techniques. Since this kind of information is not readily available, the aim of this study was to estimate the seed production ...
