A student wants to determine what type of cereal his classmates like best. He buys three of his favorite puffed cereals and one oat cereal. He pours five bowls of each cereal and gives one bowl to each of his 20 classmates. He asks each of his classmates if they liked the cereal they had or not. His data shows that more people liked puffed rice cereal than oat cereal. He comes to the conclusion that puffed rice cereal is better than oat cereal. What is wrong with the student's conclusion?
a- the student's conclusion isn't honest.
b- the student's conclusion shows cultural bias.
c- the student's conclusion shows skepticism.
d- the student's conclusion shows experimental bias.
Is this d?
Yes.
Huh, Thanks
Yes, the correct answer is d) the student's conclusion shows experimental bias.
The student's conclusion is flawed because the experiment was not conducted in a fair and unbiased manner. The student only provided one bowl of oat cereal compared to three bowls of puffed rice cereal. This uneven distribution of samples introduces experimental bias.
To conduct a fair experiment, the student should have provided an equal number of bowls for each type of cereal. This would ensure that all cereals have an equal chance of being liked or disliked by the classmates. By providing a smaller number of oat cereal bowls, there is a higher chance that fewer classmates will have the opportunity to try and like oat cereal compared to puffed rice cereal. Therefore, the student's conclusion regarding the preference of puffed rice cereal over oat cereal is unreliable.
