Question

Field observation

Answer 1

D) all groups are represented equally

Answer 2

Hey there,

By describing the word "Field observation" 

Your correct answer would be "includes interviews and informal conversations".
The reason why so would be because the word "observing" would be by looking very carefully at the object or on a sense using the word "fielf". By examining the works of the object, this would be real "field observation."

Hope this helps
