When can outliers be positive and when can they be negative for the data set?
@absentdata3 жыл бұрын
It depends on the data set. For example even if you had a outlier boundaries that's negative, it doesn't always apply. For examples a child birth dataset might not use any negative outliers then you would just use 0 as your range.

@absentdata3 жыл бұрын
In a sense yes, you may be doing a univariate analysis of the three businesses. For example you may be looking at Revenue across all the three businesses in comparing their distributions. You can compare the shape of the distribution whether it's a normal distribution or a very skewed distribution. Skewed distributions are affected by outliers.

What is the basis for the 1.5 multiplied to the IQR? What is the rationale for that? Thank you!
@absentdata3 жыл бұрын
This is part of the accepted original formula. Essentially quartiles can be scaled to standard deviations. The math equates 1.5×IQR to under 3 standard deviations from the mean. So the 1.5 was designed in the formula to capture the majority of outliers assuming the data is normally distributed.
@ragexbabayega40582 жыл бұрын
What if the lower quartile is negative in value, then our IQR turns in a really large value of Q3+Q1, will this affect the values of outliers?

No it should be fine.. However it depends on the data. Should you have negatives or not might be a better question
