Public opinion can be measured through referendum.

Referendum is the submission to the electorate for approval or rejection of some aspects of legislation. It is a nice tool for measuring public opinion. Thhis is so due to the fact that it gives out an aggregate view of the people's opinion on a particular public policy. Other methods of measuring public opinion are:

1. Direct Observation

2. Survey or Opinion Poll

3. Secondary Sources e.g Information from libraries

4. Election

5. Through Mass Media.
