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, <em>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.</em>
