WebStandard deviation is how many points deviate from the mean. For two datasets, the one with a bigger range is more likely to be the more dispersed one. IQR is like focusing on the middle portion of sorted data. So it doesn’t get skewed. Why not use IQR Range only. Use standard deviation using the median instead of mean. eric kranz dearborn countyWebFind the variance and standard deviation for the following sample data 16, 28, 31, 49, 8. Question.
