Answer:
No, Debbie's story is an argument by anecdote, and it can lead to
wrong conclusions.
Step-by-step explanation:
An argument by anecdote is when a point is proven with a story. It can be a very compelling argument, and this is because people usually like the stories about other people more than they like facts.
In general, the anecdotal argument will relate to the subject matter that is being discussed. However, anecdotal evidence is unreliable because it can be unscientific or pseudoscientific due to the fact that various forms of cognitive bias may affect the collection or presentation of evidence.
As we can see in the scenario given above, Debbie's argument is unreliable because it is her personal experience and not the collective experience of all the consumers when the price increased by one cent. Also, no form of survey or research was carried out, therefore Debbie's argument is not scientific.
