A group of students performed an experiment to see whether running in place for two minutes or being in a hot room would increase body temperature.
They had five students sit in a chair for two minutes and then measured their body temperature.
They had the same five students run in place for two minutes in a hot room and then measured their body temperature after running.
They repeated the experiment three times.
They analyzed their results, they concluded that running in place does increase body temperature and that being in a hot room does increase body temperature.
