Kvantiletti

Kvantiletti is a term sometimes used in statistical contexts, particularly in informal discussions or when referring to the concept of quantiles in a simplified manner. It doesn't represent a distinct, formally defined statistical measure separate from the general concept of quantiles. Instead, it likely emerges as a colloquialism or a portmanteau. The term is constructed by combining "kvantil" (Norwegian for quantile) or a similar root with a diminutive suffix, suggesting a smaller or perhaps a more casually understood version of a quantile.

Quantiles are points taken at regular intervals from the cumulative distribution function of a random variable. Common examples of quantiles include the median (which divides the data into two equal halves), quartiles (dividing data into four equal parts), and percentiles (dividing data into one hundred equal parts). The purpose of quantiles is to provide measures of location and to understand the distribution of a dataset. They are less sensitive to outliers than measures like the mean.

The use of "kvantiletti" would therefore likely refer to any of these standard quantile measures, or perhaps a specific quantile being discussed in a less formal setting. It is important to note that in formal statistical literature, precise terminology such as "median," "quartile," or "p-th percentile" is preferred to avoid ambiguity. The term "kvantiletti" might appear in educational materials aimed at beginners or in regions where Norwegian or similar languages influence statistical terminology.
