Which of the following is an experiment?

a) measuring the mean and standard deviation of measurements from a sample

b) generating outcomes based on some model of how they are really produced

c) comparing the outcomes of two different treatment protocols

d) recording the high and low temperature at a particular location every day

D) recording the high and low temperature at a particular location every day.

Explanation:

A experiment is a process which is conducted or performed to either support, refute or validate the hypothesis. It involves the detail repeatable procedure and the logical analysis of the outcomes of the results. It involves different variables which are compared to obtain the outcome of the experiment. For example the amount of water used everyday responsible for the plant height.

Among the options given, D) recording the high and low temperature at a particular location every day. is the correct option, temperature is a variable in the experiment. The change in the daily temperature of a location can be noted as observation of the experiment. This observation can be used to record the average temperature of the location.  

c most likely

hop this let me know if it is wrong
