It would seem though that some would not be able to be used with others due to the nature of the research and the requirements. I found your quasi-experimental study and your experimental study to be the most effective with regards to the manner in which the data was collected and the method which was used to obtain the results. I like how you used research in the same topic to compare. The experimental research I believe would be the most relevent mostly due to this being the gold standard and that there is so much control over the variables.

A t-test is a type of inferential statistic used to determine if there is significant difference between the means of two groups, which may be related in certain features. The t-test is one of many tests used for the purpose of hypothesis testing in statistics. Reference Kenton, W. (2019). T-test Definition.

Article 1. Uninterrupted sleep is of vital importance for restoration and regaining health. In intensive care units (ICUs) where recovering and healing is crucial, patients’ sleep often is fragmented and disturbed due to noise from activities from oneself, other patients, and alarms. The aim of our study was to explore if sleep could be improved by modifying the sound environment in a way that is practically feasible in ICUs. We studied the effects of originally recorded ICU noise and peak reduced ICU noise on sleep in healthy male participants. Sleep was registered with polysomnography (PSG) during four nights: one adaptation night, one reference (REF) night, and the two exposed nights with similar equivalent sound levels (47 dB LAeq) but different maximum sound levels (56- vs 64-dB LAFmax). The participants answered questionnaires and saliva cortisol was sampled in the morning. Noise in ICUs impairs sleep and the reduction of maximal A-weighted levels from 64 to 56 dB is not enough to have a clear improved effect on sleep quality. Quasi-Experimental Research Design: A type of quantitative research design that is partially controlled that studies cause and effect of variables (Helbig, 2018). Article 2. A Quasi-experimental study using cross-sectional surveys to determine whether simultaneous school start time changes (delay for some schools; advance for others) impact adolescents sleep. A 50-minute delay was enabled for high schools and secondary schools and a 30 minute advance stat time for middle schools. Both advances and delays in school start times are associated with changes in adolescents' school-night sleep duration and daytime sleepiness. Larger changes might occur with later start times. Nonexperimental Research: A research study that does not involve an experimental drug, treatment, or procedure. Article 3. This nonexperimental Research was performed to determine whether ventilated, low birth weight infants treated with closed versus opentracheal suction in a neonatal intensive care unit (NICU) differ as to airway bacterial colonization, nosocomial pneumonia, bloodstream infection (BSI), incidence and severity of bronchopulmonary dysplasia (BPD), neonatal mortality, frequency of suction, reintubation, and nurse preference. Although slightly more expensive, closed suction is perceived by nursing staff to be easier, less time-consuming, and better tolerated by small premature infants requiring mechanical ventilation for > or = 1 week.
