Question
1. When researchers conclude that their hypotheses are supported based on samples, when in reality the hypotheses are not true of the populations, the researchers have made __________________.
2. Statisticians do not rely on the results of one study; thus, _____________ is central to the connection between research and understanding.
3. Anna has conducted a study to test the hypothesis that fear correlates to the number of news stories about violence a person has watched. In the population of people, assume that there is a correlation between fear and news watched. Assume also that Anna's results from a sample of the population do not clearly indicate what is true in the population. Therefore, Anna concludes that the null hypothesis is true and that her research hypothesis is not. Which error has been made?
critical value errorsExplanation / Answer
1.When researchers conclude that their hypotheses are supported based on samples, when in reality the hypotheses are not true of the populations, the researchers have made type 2 error. 2.Statisticians do not rely on the results of one study the, correlation is central to the connection between research and understanding. 3.There is no error in this example,since Type 1 and Type 2 errors only involve rejecting or retaining the null hypothesis.Type I errors happen when we reject a true null hypothesis.Type II errors happen when we fail to reject a false null hypothesis
