It's a little hard to tell what you're asking. What is "respondent data"? (I assume you meant "response"?) What are "customer issue[s]"? What are you trying to find out about the data? Try to explain in detail what you're trying to do, and someone will be able to help.

I suspect p5 and p95 are the fifth percentile and the 95th percentile. You can calculate those in Excel, and I assume just about any statistical software would do that. The "span" is probably the difference between the fifth and the 95th percentiles.

Hi, the below data are our customer service department respond customer requirement.
1,2,3,1,2,0,9,0,10,2,3,4,3,2,1,2,2,0,3,2( 0 means customer service give call back at the same day).
these data is no-normal, so how can I calculate p5--p95, by excel or by Mintab? does anybody can tell me how to do that in detail step? I will appreciate your help.

In Excel you can use the Percenitle function. The p5 and p95 for the above data is 0 and 9.05 respectively. Percentile calculates are distribution free and do not require normality assumptions.
