Weba. t scores are used when a study is analyzed with a one-tailed test. b. t scores are used when the population variance is unknown. c. t scores are used only when the sample size is greater than 30. d. t scores are used only when inferences are … WebNov 22, 2024 · $\begingroup$ @Saskia one-sided CIs are rarely reported because one-sided hypotheses are uncommon in practice. To frame it another way, a two-sided test at significance $\alpha$ is the same as a one-sided test at significance $\alpha/2$. So you might as well test the two-sided hypothesis or construct a two-sided CI. $\endgroup$ – WebI’m working on a Paired-Samples t Test, and it’s for a one-tailed hypothesis. It’s asking if there’s a significant decline between 2 data points for each subject.. My impulse is to say that in this case, since negative values vs. positive values hold a special significance here, you wouldn’t use the absolute value of the differences because some of the data points … moss park infants
