Ascientist designed and conducted an experiment based on a hypothesis, and then formed a conclusion from her results. next, she collected and analyzed more data and formed another conclusion. which statement best justifies the fact that she skipped the hypothesis and experimental design steps of the scientific method?
the scientist must have realized that she performed one of the steps incorrectly.
the scientist was unhappy with the first data set and started the experiment over.
the scientist was repeating the experiment to improve the validity of her data.
the scientist was planning to form a hypothesis after completing the experiment.
