Least variability in math
NettetThis is close to the variance. You obtained a 2 (which is correct). And this IS a measure of variability for Y: not all of the Y-values are equal, so there is variability among the Y's! When we take X into account, we'd see that we have a deterministic relationship, but if we look at each variable alone, there are differences, and hence ... Nettet30. jul. 2024 · The 3 most common measures of central tendency are the mode, median, and mean. Mode: the most frequent value. Median: the middle number in an ordered dataset. Mean: the sum of all values divided by the total number of values. In addition to central tendency, the variability and distribution of your dataset is important to …
