In your table it's basically row number. The third column is the difference between actual y value for the i -th data point and the predicted y value (by line of best fit) using the i -th x value. This is typical use of the subscript i.

Web24 May 2024 · The center falls on the population mean because random sampling tends to converge on this value. The variability, or spread, describes how far sample means tend to fall from the population mean. The wider the distribution, the further the sample means tend to fall from the population mean. WebMean, median, and mode are different measures of center in a numerical data set. They each try to summarize a dataset with a single number to represent a "typical" data point …
In statistical theory, a U-statistic is a class of statistics that is especially important in estimation theory; the letter "U" stands for unbiased. In elementary statistics, U-statistics arise naturally in producing minimum-variance unbiased estimators. The theory of U-statistics allows a minimum-variance unbiased estimator to be derived from each unbiased estimator of an estimable parameter (alternatively, statistical functional) for large class…
