An engineering company is testing a new weather-forecasting program. Which procedure would best verify that the program is making accurate predictions?
Independent Variable
triple beam balance
100 milliliter graduated cylinder
fertilizer
comparing the predictions of the program to the actual weather
you want to have many controls
Dependent Variable
the conclusion claims that their is a cause and effect without evidence
