Question

One of the group members burning the saltine and the chip disagreed with the hypothesis. The two foods both contain starch was the student's rational for her objection. "The temperature difference is a result of measurement error. How would you respond to this student?

Answer 1

The validity of the hypothesis cannot be confirmed or refuted from only one experiment. By using a series of experiments, the human error or measurement error is reduced to a minimum. Furthermore, more than one factor can be used to determine the validity of the hypothesis.  

I will respond to this student that the experiment needs to be repeated multiple times before a conclusion can be drawn! Also, the data will refute or confirm the validity of the hypothesis and not the researcher's own opinion/rational.

Answer 2
