Relating to the process of inserting something into a text or data set, often to fill in gaps or to make adjustments.
The interpolative method was used to estimate the missing values in the dataset.
Interpolative → It is formed from "inter-" (meaning between) and "polare" (from Latin, meaning to make smooth or to polish) and the suffix "-ive" (meaning having the nature of). The word "interpolative" refers to the nature of making something smooth or polished between other elements, often used in the context of inserting or adding information between existing data.
Think of something that makes things 'smooth' or 'polished' ('polare') in between other elements ('inter-'). This helps you remember that 'interpolative' relates to inserting or adding information between existing parts.
