WebSep 11, 2014 · We consider a random variable x and a data set S = {x 1, x 2, …, x n} of size n which contains possible values of x.The data set can represent either the population being studied or a sample drawn from the population. Looking at S as representing a distribution, the skewness of S is a measure of symmetry while kurtosis is a measure of peakedness … WebParallel lines do not intersect, whereas the same line will share all points. So setting the parametrizations equal to each other and solving equations will allow you to determine whether they intersect or not. r 1 ( t) = r 2 ( s) means that − 2 + 3 t = 2 − 6 s, 3 + t = 3 − 2 s, 1 − 3 t = 4 + 6 s. The second equation says t = − 2 s. WebSep 28, 2024 · Skewness measures the deviation of a random variable’s given distribution from the normal distribution, which is symmetrical on both sides.
