D1, 4 and 5 only

Correct answer: (C) 3, 4 and 5 only

Explanation

The advantages are that many people can be empanelled, data collection becomes easy, and it can be done rapidly.

A large standing internet panel gives ready access to numerous respondents over repeated waves.

Collecting responses online is convenient for both researcher and participant, easing repeat contact.

Online data gathering is fast, cutting the delays of postal or face to face waves.

The claim that internet panels represent the entire population is false, since coverage is uneven.

The claim that everyone has internet access is false, and this digital divide biases such panels.
