Hallo!

I have the following problem:

I have this data

44

41

90

55

What I have tried so far (with R):

Chi-squared test for outlier

X-squared = 2.0888, p-value = 0.1484

alternative hypothesis: highest value 90 is an outlier

Dixon test for outliers

Q = 0.7143, p-value = 0.1544

alternative hypothesis: highest value 90 is an outlier

I also tried an Grubbs test (I found a tool online at: http://www.graphpad.com/quickcalcs/Grubbs1.cfm )

I got a critical Z value of 1.45 (1.48 would be significant).

I want to get the value of 90 out by an outlier test. I am not too experienced in outlier testing (I have no experience ). So could anybody name me a test, that is more "sensitive" concerning outliers so that th value of 90 is thrown out of my data? Thanks a lot!

Yours Hubert
