Sounds like either homework or someone who is in over their head at work. Either way, you are doomed.

And, attributes depend on the product.

Have you searched the web, or do you want us to do your work for you?

Like I said, how can you identify attributes if you don't know what the item is?

What is the definition of attribute data?

Go out on street with Camera.

Attribute good is "blond hair" or "red hair"

Attribute fail is "Not blond hair" or "not red hair" etc.

Count, Tally, Construct p-chart. Analyze.

Attributes that can be substituted for hair color can include Tall, Short, High Heels,Tennis shoes, Suit, Jewelry, Ford, Toyota, car(not truck) etc etc etc.

Take 100 photos. There is your data. 20 subgroups of 5.

I assign photos of crowds in a sporting event to my students. Wearing home team colors, not wearing any team colors, (civilian clothes only) Wearing opposing team colors. Not wearing any shirts...

Or take 100 coins and make attribute "date on coin will be within last five years." Defective is prior than last five years.

Or 100 manhole covers, Attribute is no missing letters.

I can't imagine not being able to find data in our world. Or do you need it to be "official data?"
