Assuming you're referring tot his, the key difference appears to be observations versus values.
If you have duplicate values that's when the results may differ.
This part of the example illustrates the difference:
Output 4.3.2 shows that the values 78 and 80 occurred twice for Diastolic and the maximum of Diastolic is 110. Note that Output 4.3.1 displays the value of 80 twice for Diastolic because there are two observations with that value. In Output 4.3.2, the value 80 is only displayed once.
Does that help?

Hello,
In my SAS programming course that I'm taking online, I'm on lesson 3 and I have learned how to change the number of extreme values in an observation by using the nextrval option. I referred to it in an area of the SAS documentation called "Identifying Extreme Observations and Extreme Values". I applied this statement to my programming code and after running the program, the number of extreme observations did not change, but then in the solution the option was nextrobs. Why was this used instead of nextrval and are there different options that I may use to change the number of extreme observations starting with next? I'm confused here, so any clarity will be appreciated in advance.
Thank You
