Journalist asked a sample of 1080 consumers what do they approve of the president's job performance. What type of data source is this?

a. simulation

b. experiment

c. survey

You are conducting a survey.

A simulation is something that mimics a different situation. For example, if you draw a circle in a square and throw a dart which always lands inside the square, this will give you pi when you throw enough darts at the figure.

An experiment is something that gives a number when comparing a dependent and independent variable. That's not what this condition is.
