The phrase "ability of the scale" is correct and usable in written English.
It can be used when discussing the capacity or functionality of a scale, such as in measurements or assessments.
Example: "The ability of the scale to measure weight accurately is crucial for our experiment."
Alternatives: "capacity of the scale" or "functionality of the scale".
Comparison of model results with full-scale measurements shows the ability of the scale model to reproduce patterns observed in full scale, and to reveal distinctions that are impractical to quantify using field studies alone.
The discriminant ability of the scale was determined using the person separation index (PSI) and person reliability (PR) values which measure the ability of the scale to distinguish distinct levels of participant ability.
The PSI and PR values were 2.66 and 0.88, respectively, which indicates satisfactory discriminant ability of the scale.
The PSI was good (0.91) indicating the ability of the scale to differentiate more than 4 groups of patients [ 52].
The PSI was 0.94, indicating the ability of the scale to differentiate at least 4 groups of patients [ 52].
The PSI was good (0.76) indicating the ability of the scale to differentiate between 3 groups of patients.
To assess the ability of the scales to appropriately target the population being measured, person-item threshold distribution maps were inspected.
Ceiling and floor effects at baseline and 6 months after surgery were examined to evaluate the discriminatory ability of the scales.
The relationship between item (mis)fit and clinical utility was explored by assessing the impact of the removal of misfitting items from the instrument on the ability of the scales to detect differences in scores between different patient groups in a clinical trial.
The present strategy depicted the dual functional ability of the fish scale extract as reducing and stabilising agents.
