• uses questionnaires or interviews to gather information about specific aspects of participants' behavior

• engages in careful observation of behavior without intervening directly with subjects

• conducts an in-depth investigation of an individual subject

Eloise-J believes people will form better initial impressions of people dressed in business clothes than of people dressed in casual clothes. She designs a study in which 10 people meet "Angla" when she is wearing a business suit and 10 people meet "Angla" when she is wearing jeans and a scruffy t-shirt.

• Angla’s concern about being stalked on Facebook by the subjects

• Angla's style of dress (business clothes or casual)
