Application of student's t-test, analysis of variance, and covariance.
Mishra P, Singh U, Pandey CM, Mishra P, Pandey G. Mishra P, et al. Ann Card Anaesth. 2019 Oct-Dec;22(4):407-411. doi: 10.4103/aca.ACA_94_19. Ann Card Anaesth. 2019. PMID: 31621677 Free PMC article.
Student's t test (t test), analysis of variance (ANOVA), and analysis of covariance (ANCOVA) are statistical methods used in the testing of hypothesis for comparison of means between the groups. The Student's t test is used to compare the …

Optimal weighted two-sample t-test with partially paired data in a unified framework.
Guo X, Wang Y, Zhou N, Zhu X. Guo X, et al. J Appl Stat. 2020 Apr 20;48(6):961-976. doi: 10.1080/02664763.2020.1753027. eCollection 2021. J Appl Stat. 2020. PMID: 35707734 Free PMC article.
In this paper, we provide a unified framework for two-sample t-test with partially paired data. We show that many existing two-sample t-tests with partially paired data can be viewed as special members in our unified framework. ...We also propose the a …

The Differences and Similarities Between Two-Sample T-Test and Paired T-Test.
Xu M, Fralick D, Zheng JZ, Wang B, Tu XM, Feng C. Xu M, et al. Shanghai Arch Psychiatry. 2017 Jun 25;29(3):184-188. doi: 10.11919/j.issn.1002-0829.217070. Shanghai Arch Psychiatry. 2017. PMID: 28904516 Free PMC article.
In clinical research, comparisons of the results from experimental and control groups are often encountered. The two-sample t-test (also called independent samples t-test) and the paired t-test are probably the most widely used tes …

A method of comparing the areas under receiver operating characteristic curves derived from the same cases.
Hanley JA, McNeil BJ. Hanley JA, et al. Radiology. 1983 Sep;148(3):839-43. doi: 10.1148/radiology.148.3.6878708. Radiology. 1983. PMID: 6878708
This paper refines the statistical comparison of the areas under two ROC curves derived from the same set of patients by taking into account the correlation between the areas that is induced by the paired nature of the data. The correspondence between the area under an ROC …

Analysis of Paired Data.
Franc JM. Franc JM. Prehosp Disaster Med. 2025 Apr;40(2):61-63. doi: 10.1017/S1049023X25001517. Epub 2025 Apr 11. Prehosp Disaster Med. 2025. PMID: 40213959
In many studies, there is a set of individual participants or experimental objects where two observations are made on each individual or object. This leads to a natural pairing of data. This editorial discusses common situations where paired data arises and gives gu …

Testing Internal Quality Control of Clinical Laboratory Data Using Paired t-Test under Uncertainty.
Albassam M, Aslam M. Albassam M, et al. Biomed Res Int. 2021 Sep 4;2021:5527845. doi: 10.1155/2021/5527845. eCollection 2021. Biomed Res Int. 2021. PMID: 34527738 Free PMC article.
In this paper, the modification of the paired t-test under neutrosophic statistics is proposed. The testing criterion of the proposed paired t-test is given. The application of the proposed paired t-test is given usin …

The paired t-test as a simple latent change score model.
Coman EN, Picho K, McArdle JJ, Villagra V, Dierker L, Iordache E. Coman EN, et al. Front Psychol. 2013 Oct 10;4:738. doi: 10.3389/fpsyg.2013.00738. eCollection 2013. Front Psychol. 2013. PMID: 24124419 Free PMC article. No abstract available.
Whiteness difference thresholds in dentistry.
Pérez MM, Herrera LJ, Carrillo F, Pecho OE, Dudea D, Gasparik C, Ghinea R, Bona AD. Pérez MM, et al. Dent Mater. 2019 Feb;35(2):292-297. doi: 10.1016/j.dental.2018.11.022. Epub 2018 Dec 6. Dent Mater. 2019. PMID: 30527588
Images of simulated upper central incisors (SUCI) were consecutively displayed in pairs (60) and the whiteness of each SUCI pair was compared. WI(D) was used to calculate the visual thresholds (WPT- perceptibility threshold; and WAT- acceptability threshold) with 95% confi …
