Question

Quizplus · Accepted Answer

By deciding not to spend money on new computer equipment based on the assumption that there was no statistically significant difference in learning between students taught by computers or books, the school administrator may have made a Type II error or a false negative. This means that she wrongly concluded that there was no difference in learning between the two methods of teaching, when there actually was a difference. The successful implementation of computer technology in a neighboring district further supports the possibility of the school administrator making a Type II error.
