It depends on what's being measured. Sometimes it's better to have variable data, as in instances where it's important to identify relatively small amounts of variation, and in other instances, attributes data will do, if all you need to know is whether a thing is "good" or "bad" without regard for incremental changes in variation.

Depends on the Application

Attribute, or go no-go, type inspection is faster in most cases, and doesn't require the same skill levels as variable type inspection.
Variable inspection is more accurate and provides better feedback where you are trying to control a process.

If you can give some detail we can probably give a little better answer.

Based On Requirement

Hi,

:)

here we go,

The variable & attribute have their own advantages & disadvantages.
Based on the customer requirement & drawing spec you need to decide.

When ever a customer asks for a Cp/Cpk result he will be expecting a variable study report & you have no other go you need to go for an Varibale type of inspection. It's not that with a attribute type of measurement we won't get the Cp/Cpk. As James rightly said its based on the application and also the customer requirement & also the attribute type of inspection is fast when compared to variable type of inspection.
The variable type of inspection requires more skill & knowledge to read.
And the data got thru variable type of study helps you in taking good & right decision @ right times.
