Question

On April 16, 2007, the BBC news reported the results of a study done by Dr. David Lewis of the Mind Lab in the United Kingdom. Dr. Lewis found that eating dark chocolate had longer-lasting excitatory effects on the body than did kissing your romantic partner. This is the first study to show such large effects of chocolate. If no subsequent studies can replicate this finding, it implies that the researchers made what kind of error?

Answer 1

Answer:

Type I

Explanation:

Type I error is also known as Alpha error or false positive(finding or conclusion) that occurs when people negate the Null Hypothesis (contradictory statement to one's hypothesis) even if it has strong chances of being true. The researchers usually form a null hypothesis in order to produce a balanced hypothesis or conclusion. Therefore, the given example illustrates that if the researchers' finding is not replicated well by successive studies then it is implied that they have made type I error as they have rejected the true null hypothesis.
