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 it d?

Yes, the answer is D.

looks right to me ;D

Yes, the correct answer is d- the student's conclusion shows experimental bias.

The student's conclusion is based on a biased experiment design. The student only tested three types of puffed cereals and one oat cereal. By providing more options of puffed cereals compared to the oat cereal, the student has introduced bias into the experiment. This bias can influence the results and the conclusion. To draw a fair conclusion, the student should have tested an equal number of bowls of each type of cereal. This would have ensured that the experiment was not biased towards any specific type of cereal.
