The median is a robust measure of central tendency. Taking the same dataset {2,3,5,6,9}, if we add another datapoint with value -1000 or +1000 then the median will change slightly, but it will still be similar to the median of the original data.

Robust Statistics for Variation The standard deviation is similar to the mean because its calculations include all values in the data set. A single outlier can drastically affect this statistic. Therefore, it is not robust.

Notably, the median is more robust to skewed distributions and outliers than the mean. Read more about The Median. For the body fat percentage data, the median is 27.35%. Half the values in the sample are above this value, while half are below it.

For statistics, a test is robust if it still provides insight into a problem despite having its assumptions altered or violated.

Updated on July 11, 2019. In statistics, the term robust or robustness refers to the strength of a statistical model, tests, and procedures ing to the specific conditions of the statistical analysis a study hopes to achieve.

Data Robustness is the overall degree to which a given dataset can tolerate variations in its collection and integration procedures without suffering a loss of information content, statistical validity, and/or scientific meaning. It refers to the quality of data collected, and refers to whether it is weak or strong.

Robust Estimators of the Dispersion The standard deviation is the classical measure of the statistical dispersion, but it is not robust since it can be made arbitrarily large by a single outlier. The most common robust estimators of the dispersion are the median absolute deviation and the interquartile range.

We find the robust standard deviation estimate by multiplying the MAD by a factor that happens to have a value close to 1.5. This gives us a robust value ('sigma- hat') of B . . If we use this method on data without outliers, it provides estimates that are close to x and s, so no harm is done.
