The name of the least squares line explains what it does. We start with a collection of points with coordinates given by (xi,yi). Any straight line will pass among these points and will either go above or below each of these. We can calculate the distances from these points to the line...
Note:Just as that of range, IQR uses two values for the calculation. But IQR gets less effect with the outliers. In addition to this, IQR provides consistent variability for normal and skewed distribution. Standard deviation The SD is the mean of variability that tells how far the score is...
The box is used to represent the interquartile range (IQR) — or the 50 percent of data points lying above the first quartile and below the third quartile — in the given data set. The whiskers are used to represent the variability of the minimum, maximum and any outlier data points in...
