(1 of 2) You like to eat tuna fish sandwiches. Recently you have noticed that there does not seem to be as much tuna as you expect when you open the can. Identify the type of data (anecdotal or availabe) that this represents and describe how it can or cannot be used to reach a conclusion about the amount of tuna in cans of tuna fish.

(2 of 2) In a study designed to evaluate the benefits of taking Echinacea when you have a cold, 719 patients were randomly divided into four groups. The groups were (1) no pills, (2) pills that had no Echinacea, (3) pills that had Echinacea but the subjects did not know whether or not the pills contained Echinacea, and (4) pills that had Echinacea and the bottle containing the pills stated that the contents included Echinacea. The outcome was a measure of the severity of the cold.6 Identify the type of data collected in this study. Give reasons for your answer.

Solution

The type of data is Anecdotal.

It cannot be used to reach a conclusion about the amount of tuna in cans of tuna fish .Anecdotal evidence is no more than a type description (i.e., short narrative), and is often confused in discussions with its weight, or other considerations, as to the purpose(s) for which it is used. This is true regardless of the veracity of individual claims.
