Letter- This is credible, but not as much so as the others. A letter sent to Grandma Ella still must be credited if it was copied and shared, but it does not have valuable information and cannot be useful to one's knowledge.
Newspaper- This is very credible. Newspaper articles contain valuable information as in facts and statistics as well as opinions and point of views. Newspapers are also updated often so no information is old, unless you read an old article.
Data- This is also credible but supplies more information than credit. An analysis normally consists of numbers or percentages, which can still be credited but not as easily. Data consists of most people's opinions normally, as this is still a fact.
Radio- This is the least creditable. Radio stations talk about weather and current gossip, including pop stars, sports, etc. This is very hard to credit as it is live and cannot be credited without a recorder or a very good memory.
I believe I assisted, do well!
