- In the analysis of the data, researchers relied on parametric statistics to validate their hypotheses based on a normal distribution.
Examples
-
To control for differences in grade-level performance, parametric statistics were used for all analyses (see Note 2).
Academic text (2013) -
The main limitation of both is that they are parametric statistics. As such, they make assumptions about single-case data that are rarely all met.
Academic text (2013) -
When assessing the effects of medication, scientists often apply parametric statistics to ensure the underlying assumptions about the data are fulfilled.
-
Using parametric statistics allowed the researchers to derive conclusions that were statistically significant, but they acknowledged the importance of meeting distribution assumptions.

Morphology
The phrase combines 'parametric' (expressed in terms of parameters) and 'statistic' (a numerical summary), so a learner who knows both constituents can reasonably infer it refers to a statistic that depends on parameters. However, the full technical meaning — involving assumptions about specific probability distributions and methodological implications — requires subject‑matter knowledge beyond simple composition, so it is not fully predictable to a general B1 learner.
Etymology
Parametric statistic comes from the word parameter, which means a fixed rule or shape for data. Think of measuring with a template that fits one pattern. Because it uses that fixed rule, a parametric statistic only works when the data follow a 'known pattern'.
