Hi Friends,
I am new to this forum.
Can anybody help me to understand which attribute template will help for the below colour matching study :
Perform the measurement system analysis from the attribute data recorded by three observers each with two trials on the five calls given to each. The calls have been categorised in a 1-5 scale. The reference master data on the parts is also mentioned.

Hi,
Thanks for your response.
Basically I would like to know
1. if the measurement system is acceptable or not ?
2. Any improvement area ?
3. individual feedback for each observer

Any other conclusion we can have from this analysis.
Thanks,

It's not possible to help you until you explain all of the details of what you're doing.

You need to perform an attribute agreement analysis with a known standard. There are three potential metrics you could use to assess the measurement system's fitness for use.
  • % agreement within/between evaluators
  • Kappa statistic for nominal data
  • Kendall statistic for ordinal data
