The phrase "a hypothesis that involves" is correct and usable in written English.
You can use it when discussing a hypothesis in a scientific or academic context, particularly when describing the elements or factors that the hypothesis takes into account.
Example: "The study presents a hypothesis that involves multiple variables affecting climate change."
Alternatives: "a hypothesis that encompasses" or "a hypothesis that includes".
In this model we postulate a specific hypothesis that involves the effect of an interaction term between facility services utilization and care needs level.
This has been done not necessarily to have a complete view of all the genome, but for the following two reasons: (i) to get rid of the uncertainty of potential hidden stratification that could affect the results and correct for it, if needed; (ii) to have our data set genotyped once, and to concentrate on a specific hypothesis that involves one genetic mechanism or pathway at a time [13].
To account for the tree topologies observed in our study we propose an alternative hypothesis that involves repeated symbiont acquisitions from a common bacterial "progenitor" that is ubiquitous in the environment.
In brief, the test assesses whether the branch being studied provides a significant likelihood gain, in comparison with the null hypothesis that involves collapsing that branch, but leaving the rest of the tree topology identical.
Advantages of the structured approach are that it requires the hypotheses to be carefully specified a priori, and can accommodate complex compound hypotheses that involve interactions.
In addition, scientists generally strive to develop simple hypotheses, since these are easier to test relative to hypotheses that involve many different variables and potential outcomes.
If the population is large enough, study hypotheses that involve infrequent outcomes or exposures can be addressed as well as hypotheses that involve small effects of common exposures and outcomes[ 4].
Therefore, hypotheses that involve protein protein interactions are more likely the source of the observed phenotypes and should be investigated further.
The existence of the missing taxon has been supported by nearly all subsequent lines of evidence, but attempts have long been made to reinterpret the available data in support of hypotheses that involve only extant parental taxa.
These findings support a hypothesis that pathways involved in systemic vascular remodelling play a role in AAA development.
