In the regression model, age was included as a covariate to control for its effect on blood pressure.

The researchers measured the covariation between temperature and crop yield to understand their relationship.

The regression model adjusted for several covariates to isolate the treatment effect.

When modeling climate impacts, researchers often find that temperature and precipitation covary in ways that influence ecosystem responses.

Over the decade, the two indicators covaried, reflecting how closely their fluctuations were linked.

In the experiment, plant stress covaries with soil moisture as sunlight increases.

The botanist noted several traits covarying across different populations of the species.

When studying algebraic curves, covariants often reveal symmetries that are not immediately apparent.

When analyzing ecological data, researchers must account for covariations between species abundance and climate variables to avoid misleading conclusions.

When analyzing the dataset, researchers controlled for several covariables to isolate the treatment effect.
