Feeling thermometer

A feeling thermometer, also known as a thermometer scale, is a type of visual analog scale that allows respondents to rank their views of a given subject on a scale from "cold" (indicating disapproval) to "hot" (indicating approval), analogous to the temperature scale of a real thermometer. It is often used in survey and political science research to measure how positively individuals feel about a given group, individual, issue, or organisation, as well as in quality of life research to measure individuals' subjective health status. It typically uses a rating scale with options ranging from a minimum of 0 to a maximum of 100. Questions using the feeling thermometer have been included in every year of the American National Election Studies since 1968.
