How study types work

Studies can vary depending on the research goal, but they all aim to gather your opinions or experiences. Here are the most common types of studies you may be invited to, and what to expect from each:

Online survey

You’ll answer questions through an online form.

• Usually takes 5–30 minutes
• Can be completed anytime before the deadline
• No interaction with a researcher

Telephone interview

You’ll speak with a researcher over the phone.

• Scheduled in advance
• Typically lasts 30–60 minutes
• You’ll be asked questions and share your experiences

Telephone interview (with computer access)

Similar to a phone interview, but you may also need to:

• Access a website or materials during the call
• Share feedback in real time while using your device

Online discussion board

You’ll participate in a moderated online forum over several days.

• Log in daily to answer questions or complete tasks
• Interact with other participants in some cases
• Flexible timing within each day

Focus group

You’ll join a small group discussion led by a moderator.

• Can be online or in person
• Usually lasts 100–180 minutes
• You may be asked to share opinions and react to others

In-person interview

You’ll meet a researcher at a specific location.

• Scheduled ahead of time
• May involve activities, product testing, or discussions
• Duration varies depending on the study

Good to know

• You’ll always receive details (timing, format, requirements) before participating
• Some studies may require a webcam, microphone, or specific device
• You may be asked to complete a short pre-work assignment before the session (such as answering questions or preparing materials) 
• In some cases, you may also receive homework after the session, like follow-up tasks or additional feedback
• Incentives are provided after successful participation
