Textbook Question
Chapter 1, Problem 7RQ
How many experiments are necessary to invalidate a scientific hypothesis?
Expert Solution & Answer
To determine
The number of experiments that are necessary to invalidate a scientific hypothesis.
Answer to Problem 7RQ
Only one experiment with contradictory results is necessary to invalidate a hypothesis.
Explanation of Solution
A hypothesis is a type of proposed explanation by consideration of some evidence. A hypothesis is also referred as an educated guess that is used to give a logical analysis of observation.
When a hypothesis is verified experimentally and has been proved to hold good each time without exception, then it becomes a law or principle. However, if a hypothesis fails only once, then it becomes invalidated.
Conclusion:
Therefore, only one experiment with contradictory results is necessary to invalidate a hypothesis.

Abstract - This document outlines the format of the lab report and describes the Excel assignment. The abstract should be a short paragraph that very briefly includes the experiment objective, method, result and conclusion. After skimming the abstract, the reader should be able to decide whether they want to keep reading your work. Both the format of the report and the error analysis are to be followed. Note that abstract is not just the introduction and conclusion combined, but rather the whole experiment in short including the results.
