this is a problem better addressed through specific examples. Could you possibly post an example problem where you need to find outliers and range?
1) Arrange the data in increasing order by size
2) If the count of your data points is odd, take the middle point and dub it your "median."
If the count is even, take the middle 2 points and average them to obtain the "median"
3) subtract the largest data point (on the right) from the smallest (on the left). This gives you the range.
4) determine the 1st and 3rd quartiles. Treat the left half of the data as a separate set and find the median of this set; your result is the 1st Quartile;
Do the same for the right half; your result is the 3rd Quartile.
4. Calculate the Interquartile range (IQR). Do this by subtracting the 1st Quartile from the 3rd.
4) Set up "outlier" fences. Focus on the median. Calculate the right outlier fence by taking 1.5 times the IQR, adding your result to the median and plotting this. Calculate the left outlier fence in the same way, except subtract 1.5 times the IQR from the median.
It's easy once you've done this a few times. Now, please, would you share a specific problem to which we could apply these procedures? Thanks.
