I am confident enough to claim that a two-tailed test is generally more appropriate in some cases as it can produce more precise conclusions with a lower risk of false positives or false negatives. I can explain further how this is true. For instance, if we need to know whether a certain treatments are beneficial or not. 1) To find the proportion of benefit, we can do a one-tailed test (e.g. Can I make a one-tailed test in this case? Yes, it is possible). In this case,

One-tailed tests are the traditional way of testing hypotheses with a single comparison group. Here are steps to calculate it for homework: 1. Determine the alpha and beta for the significance level. For one-tailed tests, alpha is a p-value you want to reject or accept. Beta is the proportion of true positive to true negative outcomes. 2. Calculate the proportion of true positives (i.e., positive outcome, P(X>0)) by multiplying the proportion of positive outcomes by the proportion of positive group (p

In statistics, a one-tailed test is an analytical procedure used to determine whether a null hypothesis (that there is no difference between two independent samples) is true. Two-tailed tests are used to determine whether a null hypothesis is true or false (i.e., whether a difference exists between two independent samples). When calculating one-tailed tests in homework, you must check to see if you want to test one or two sample sizes. I should have been more specific, as below. In statistics, a one-tailed test is an analyt

“How to calculate one-tailed vs two-tailed tests in homework?” In first-person tense (I, me, my), I will discuss one-tailed vs two-tailed tests. Click This Link I’m a college professor who has taught and coached many students in the past few years, and I know that many of them have a tough time understanding the distinction between one-tailed and two-tailed tests. In one-tailed tests, the null hypothesis (H0) is accepted if the sample mean is less than or

Taking one-tailed test is more appropriate when the null hypothesis is true and the alternative hypothesis is false. It involves testing whether a group or a population has an equal distribution with respect to the null hypothesis. In such cases, we expect to get only one result, that is, the difference between the means of the two groups will be the same. On the other hand, testing the null hypothesis with a two-tailed test involves testing whether a group has an equal distribution with respect to the null hypothesis, but the alternative hypothesis is also true. The null hypothesis is

One-tailed or two-tailed tests In general, you need to calculate a one-tailed or two-tailed test using the formula _T_ = (mean difference/std. deviation) x 2, with _T_ the sign of the _T_ -statistic. To do this in your homework, open your calculator or laptop. In the test (or study) you are calculating the _T_ -statistic, and enter your sample size (number of observations) and standard deviation (standard deviation). Enter the

In homework, sometimes students are required to calculate one-tailed or two-tailed tests, and the question of whether the null hypothesis (H0) is rejected or not is a vital one for the students. While calculating tests, the null hypothesis is that the true value lies in the specified range of values. Now let’s do some steps to calculate both tests: 1. One-tailed test: The null hypothesis here is H0:α = 1, α is the critical value for 1-tailed test. Let’
