Question

Which of the following is an experiment?

1. measuring the mean and standard deviation of measurements from a sample
2. generating outcomes based on some model of how they are really produced
3. comparing the outcomes of two different treatment protocols
4. recording the high and low temperature at a particular location every day

Answer 1

Part of an experiment is collecting ( recording data).

The answer would be: 4. recording the high and low temperature at a particular location every day.

Recording the temperatures allows you to determine the average temperature of that location.
