  2. Mid-range - Wikipedia

    en.wikipedia.org/wiki/Mid-range

    The mid-range is closely related to the range, a measure of statistical dispersion defined as the difference between maximum and minimum values. The two measures are complementary in sense that if one knows the mid-range and the range, one can find the sample maximum and minimum values.

  3. Midhinge - Wikipedia

    en.wikipedia.org/wiki/Midhinge

    The two are complementary in sense that if one knows the midhinge and the IQR, one can find the first and third quartiles. The use of the term hinge for the lower or upper quartiles derives from John Tukey's work on exploratory data analysis in the late 1970s, [1] and midhinge is a fairly modern term dating from around that time.

  4. L-estimator - Wikipedia

    en.wikipedia.org/wiki/L-estimator

    L-estimators are often much more robust than maximally efficient conventional methods – the median is maximally statistically resistant, having a 50% breakdown point, and the X% trimmed mid-range has an X% breakdown point, while the sample mean (which is maximally efficient) is minimally robust, breaking down for a single outlier.

  5. Range (statistics) - Wikipedia

    en.wikipedia.org/wiki/Range_(statistics)

    In descriptive statistics, the range of a set of data is size of the narrowest interval which contains all the data. It is calculated as the difference between the largest and smallest values (also known as the sample maximum and minimum). [1]

  6. Interquartile range - Wikipedia

    en.wikipedia.org/wiki/Interquartile_range

    Boxplot (with an interquartile range) and a probability density function (pdf) of a Normal N(0,σ 2) Population. In descriptive statistics, the interquartile range (IQR) is a measure of statistical dispersion, which is the spread of the data. [1]

    Analysts say the mid-range pricing strategy aims to woo price-sensitive customers in countries like China and India and boost adoption in lower-end markets. But on a global scale, Apple still ...

  8. Central tendency - Wikipedia

    en.wikipedia.org/wiki/Central_tendency

    Thus standard deviation about the mean is lower than standard deviation about any other point, and the maximum deviation about the midrange is lower than the maximum deviation about any other point. The 1-norm is not strictly convex, whereas strict convexity is needed to ensure uniqueness of the minimizer. Correspondingly, the median (in this ...

  9. Median - Wikipedia

    en.wikipedia.org/wiki/Median

    Instead, the closest ancestor of the modern median is the mid-range, invented by Al-Biruni [62]: 31 [63] Transmission of his work to later scholars is unclear. He applied his technique to assaying currency metals, but, after he published his work, most assayers still adopted the most unfavorable value from their results, lest they appear to cheat .
