They provide immediate access to a large and diverse subject pool, and allow researchers to control the experimental context. Online experiments, we show, can be just as valid—both internally and externally—as laboratory and field experiments, while often requiring far less money and time to ...
respectively (Table S4.a.1). Manipulating seawater temperature under controlled experimental conditions (where all other confounding variables are accounted for), allows researchers to test hypotheses related to the direct effect of temperature on the response variables...
it will allow researchers to discover the bestnew drugsmuch more quickly and at a lower cost. Thirdly, it will enhance innovation, by helping shift the focus away from the tried and tested drug targets while managing the inevitable risk associated with moving into new and exciting areas. Both...

These methods allow researchers to explore heterogeneity by identifying subpopulations with different treatment effects while maintaining the ability to construct valid confidence intervals. We also discuss optimal assignment to treatment based on covariates in such settings. Finally, we discuss estimation and...
Psychophysical "reverse-correlation" methods allow researchers to gain insight into the perceptual representations and decision weighting strategies of individual subjects in perceptual tasks. Although these methods have gained momentum, until recently their development was limited to experiments involving only ...

In the context of ExaC, we leverage these principles with experiment-related services, thereby making it easier for researchers to access and use experiment components without requiring in-depth technical ...
