The phrase "a more rigorous experiment" is correct and usable in written English.
It can be used when discussing the need for a more thorough or strict approach in conducting an experiment, often in a scientific or academic context.
Example: "To validate our hypothesis, we need to conduct a more rigorous experiment that controls for all variables."
Alternatives: "a more thorough experiment" or "a more stringent experiment."
Thus, while constructing a detection test, more rigorous experiments than the sole ability of phage to form plaques should be employed, in order to identify properly the specificity of phage binding.
For a more definitive proposal for the mechanisms of lignin migration within cell walls, more rigorous experiments are required.
Thus more rigorous experiments should be conducted to determine biomarker cut-off optimization and calculation of ROC curves.
This was a single-blind experiment, not a more rigorous double-blind experiment.
Next, Dr. Kane and other scientists at the Lawrence Livermore laboratory want to put the simulation results to a more rigorous test -- experiments with lasers supplying the energy in trying to reproduce such cosmic phenomena.
Using a new experiment and a more rigorous and appropriate analysis of the previous experiment (Cresswell et al. 2003), we tested whether reduced energetic demands of incubation changed incubation-scheduling.
These findings indicate that gene microarray study alone may be insufficient and a more rigorous study involving proteomics experiments or antibody microarrays are necessary to validate the candidate markers at the protein expression level.
This second experiment provided a more rigorous test of the pest management potential of the OX4319L strain as the intrinsic growth rate of target populations was not artificially controlled and competitors from these target populations had the advantage of being reared on host plant material, as opposed to an artificial diet medium.
And Siobhan Davies is experimenting with a more rigorous, gallery-style format.
