The math is usually handled by software type 1 error rate calculation packages, but in the interest of completeness I will explain the calculation in more

detail. A t-Test provides the probability of making a Type I error (getting it wrong). If you are familiar with Hypothesis

testing, then you can skip the next section and go straight to t-Test hypothesis. Hypothesis TestingTo perform a hypothesis test, we start with two mutually exclusive hypotheses. Here’s an example: when someone is accused

of a crime, we put them on trial to determine their innocence or guilt. In this classic case, the two possibilities are the defendant is not guilty (innocent of the crime) or the defendant is guilty. This is classically written as…H0: Defendant is ← Null HypothesisH1: Defendant is Guilty ← Alternate HypothesisUnfortunately, our justice systems are not perfect. At times, we let the guilty go free and put the innocent how to calculate error rate in excel in jail. The conclusion drawn can be different from the truth, and in these cases we have made an error. The table below has all four possibilities. Note that the columns represent the “True State of Nature” and reflect if the person is truly innocent or guilty. The rows represent the conclusion drawn by the judge or jury.Two of the four possible outcomes are correct. If the truth is they are innocent and the conclusion drawn is innocent, then no error has been made. If the truth is they are guilty and we conclude they are guilty, again no error. However, the other two possibilities result in an error.A Type I (read “Type one”) error is when the person is truly innocent but the jury finds them guilty. A Type II (read “Type two”) error is when a person is truly guilty but the jury finds him/her innocent. Many people find the distinction between the types of errors as unnecessary at first; perhaps we should just label them both as errors and get on with it. However, the distinction between the two types is extremely important. When we commit a Type I error, we put an innocent person in jail. When we commit a Type II

The null hypothesis, is not rejected when it is false. Type how to calculate percent errors II errors arise frequently when the sample sizes are too small and it is also called as errors of the second kind. Formula: Example : Suppose the mean weight of King http://www.sigmazone.com/Clemens_HypothesisTestMath.htm Penguins found in an Antarctic colony last year was 5.2 kg. Assume the actual mean population weight is 5.4 kg, and the population standard deviation is 0.6 kg. At .05 significance level, what is the probability of having type II error for a sample size of 9 penguins? Given, H0 (μ0) = 5.2, HA (μA) = 5.4, σ = 0.6, n = 9 https://www.easycalculation.com/statistics/learn-beta-error.php To Find, Beta or Type II Error rate Solution: Step 1: Let us first calculate the value of c, Substitute the values of H0, HA, σ and n in the formula, c - μ0 / (σ / √n) = -1.645 c - 5.2 / (0.6 / √(9)) = -1.645 c - 5.2 = -0.329 c = 4.87 Step 2: In the formula, take β to the left hand side and the other values to right hand side, β = 1 - p(z > (c - μA / (σ / √n))) [ z = x̄ - μA / (σ / √n) ] Substitute the values in the above equation, β = 1 - p(z > (4.87 - 5.4 / (0.6 / √(9)))) = 1 - p(z > -2.65) = 1 - 0.9960 = 0.0040 Hence the Type II Error rate value is calculated.
