Two-tailed tests: what is a two-tailed test? Atwo-tailed testallows you to determine if two means are different from one another. A direction does not have to be specified prior to testing. In other words, a two-tailed test will take into account the possibility of both a positive and...
Left-tailed test or Lower-tailed test The Left-tailed test is also known as a Lower-tail test. A hypothesis test is performed if the population parameter is suspected to be less than the assumed parameter of the Null Hypothesis. H0: μ≥μ0 H1: μ<μ0 Example of a One-Sample T Hypot...
Hey, I just bought the newest version of the "1byone" scale from Amazon for just 20 Euros: https://www.amazon.de/1-BY-ONE-Digitale-Personenwaage/dp/B089VPXBX6 It seems to be a very good, accurate scale. In my test runs, I could step onto...

I was also able to see the tail end of a Deal Or No Deal that day. The contestant managed to get all the way down to the final two briefcases before making a deal with the bank. I didn’t see what he ultimately got for a prize, but it was really cool seeing someone do that ...

Several studies can also be found in the literature on developing the Bayesian two-sample proportion test in contingency tables for testing the independence between rows and columns. See, for example, ref. [6] and the references therein. For the one-sample problem, ref. [7] used an improper...
Justification for this one-tail replacement of a two-tailed test is that eigenvectors are unique except for a multiplicative factor of −1; in other words, the sign of an eigenvector regression coefficient is arbitrary, converting it to a one-tail test situation. In addition, this is the ...
The value of 10 falls into the rejection region (the left tail). In other words, it’s highly likely that the mean sale is greater. The one sample t test has told us that sales training was probably a success. Want to check your work? Take a look at Daniel Soper’s calculator. ...
the stimulus presentation changed to the two choice stimuli and the door was opened. As soon as the test animal swam through the gate (crossed the line with its mouth), time (in seconds) was taken. The moment the animal crossed the decision line with its mouth, time was stopped and choi...
