Type 1 and Type 2 Errors: What They Are and How to Avoid Them

WebMar 16, 2009 · The null hypothesis can be thought of as the status quo, and the alternative hypothesis is what our experiment is telling us. You can reduce type 2 errors by increasing alpha. However, by increasing alpha, type 1 errors increase, that is to fail to accept the null hypothesis, when the alternative is, in reality, false. WebThe average cost of a lawsuit is $£240,000$, whilst the cost of a die is $£3$, so in order to minimise costs would you aim to have $240000 \,\beta = 3\,\alpha$, where $\beta$ is Type II error, A.K.A., false negative rate, and $\alpha$ is the significance level of the hypothesis test (and also the probability of a Type I error, A.K.A., false ... mtt assay review
