We have considered n number of samples during data collections subjected to verification of outcome. A random variable destroys component 1, sample B governed by random variable destroys component 2, and sample C governed by random variable destroys both components simultaneously. We refer to such a system as bivariate homogeneous shock (BHS) model. Clearly, under this model the life length of component 1 is and that of component 2 is .

Table 3 showing the coefficient of correlation between virtual reality simulators and the ARCS model [
18,
19], attention is 0.638, indicating that there are positive connections of 63.8% between virtual reality simulators and the ARCS model, attention on coordination is significant at the 1% level. The coefficient of correlation between virtual reality simulators and ARCS model, relevance is 0.607, indicating positive connections of 60.7% between virtual reality simulators and ARCS model, relevance on coordination, which is significant at the 1% level. The coefficient of correlation between virtual reality simulators and ARCS model, concentration is 0.652, indicating that there are positive connections of 65.2% between virtual reality simulators and ARCS model, concentration on coordination, which is significant at the 1% level. The coefficient of correlation between virtual reality simulators and ARCS model, satisfaction is 0.547, indicating that there are positive connections [
20] of 54.7% between virtual reality simulators and ARCS model, satisfaction on coordination, which is significant at the 1% level.
The coefficient of correlation between virtual reality simulators and the impact of virtual reality simulators on medical education using the ARCS model of learning motivation dimensions is 0.756, indicating that there are positive connections of 75.6% between virtual reality simulators and the impact of virtual reality simulators on medical education using the ARCS model of learning motivation dimensions on coordination [
22], which is significant at the 1% level. Similarly, the other variables are positively associated with one another.
HYPOTHESIS: 1
Null hypothesis (H0): The hypothesized model has a good fit.
The alternate hypothesis (H1): The hypothesized model does not have a good fit.
The model’s fitness was evaluated using structural equation modelling (SEM), which was applied to the data collected as shown in
Table 4 and
Figure 5.
If explanatory-theory discrepancies are small, its sensitivity to differences from predicted values with rising sample sizes might be troublesome. This study claims the Chi-square exact-fit test is the sole SEM fit test. Correctly scaled approximation fit indices are not sample size-sensitive. “Tests” of model fit should not replace these indices. The “consequences” of adopting an explanatory model should be balanced against theory-relevant metrics’ predictive accuracy. This might break our impasse. If there are no “competing” models, there is no reason to compare them. In the testing of the analytical model to determine the accuracy and validity of the survey instrument, the structural model was assessed using the AMOS version 23, following the recommendations of [
18]. Structural equation modelling (SEM) is beneficial for finding the causal relationship between variables and ensuring that the model is compatible with the data set being analyzed.
In structural equation modelling, the data is compared to a theoretical model developed. The design was evaluated using the chi-square/degrees of freedom 2(x
2/df), the CFI, the RMSEA, the NFI, and the P-CLOSE, as shown in
Table 4. As a consequence, the probability of
p = 0.175 was estimated. The Chi-square score of 1.837 indicates that the model is well-fitting in this case.
Chi-square statistics may be influenced by a sample size more prominent than 100 (in this study, 607 participants) to indicate that there is a significant degree of likelihood (
p = 0.175), according to [
23]. Because of this, this model is examined to be used for further investigation during the goodness of fit phases. Model fit metrics that are widely used include the Chi-square/degree of freedom (x
2/df), the comparative fit index (CFI), the approximation root means square error (RMSEA), the nonlinear fit index (NFI), and the PCLOSE. The findings of the structural modelling of AMOS are shown in
Table 4, which shows the system fit index.
According to [
24], the following characteristics of an effective template:
Table 4 shows a Chi-square/D.F. value of 1.837, which is less than 5.00, indicating an excellent match between the two variables. Confirmatory factor analysis (CFA) (0.999) and the normed fit index (NFI) were used to analyze the data (0.999) 1 is the Chi-square equivalent. A very excellent match is represented by values close to one, indicating a perfect match overall. A good fit may be determined by the PCLOSE value (0.000), which is less than 0.005, and the root mean square approximation error (RMSEA) is 0.070, which is less than 0.08, suggesting that the model is acceptable.

4.2. Essential Tests of Individual Parameters
The standardized coefficients and pertinent test data are presented in
Table 6. It is defined as the amount of change in the dependent or mediating variable for every one-unit change in the variable that predicts it, expressed as a standardized regression coefficient, as well as its standard error (abbreviated S.E.) and the standard error estimate (also known as the critical ratio, abbreviated C.R.) Column P represents the probability value associated with the null hypothesis, stating that the experiment is a complete failure.
Figure 3 depicts the parameters included in the investigation of the impact of virtual reality simulators on medical education, which was conducted using the ARCS model of learning motivation dimensions structural architecture. During the confirmatory factor assessment process, 597 students picked and answered 30 questions relating to the factors of analysis for the impact of virtual reality simulators on medical education using the ARCS model of learning motivation dimensions. As shown in
Figure 3, augmented reality simulators (VR simulators) play an essential role in the learning process in higher education. Alternatively, the confirmatory variable test is referred to as an assessment approach. By exposing the approximation square error, the root illustrates how the model will fit the population covariance matrix with unknown parameter values when the parameters are uncertain [
25]. According to [
26], CFI, RMSE, or root mean square approximation error, is a good match for the original data set.
HYPOTHESIS: 2
Null hypothesis (H0): There is no significant difference between using virtual reality simulators for medical education reducing stress and anxiety among medical students. The alternate hypothesis (H2): There is a substantial difference between using virtual reality simulators for medical education reducing stress and anxiety among medical students.
Since the p-value is less than 0.01, the null hypothesis is rejected at a 1% level regarding the virtual reality simulators for medical education reducing stress and anxiety among the respondent. Virtual reality simulators used in the finest medical training facilities have improved anatomical position learning and minimized surgical time in the real world. Increased patient and physician safety, and good psychological impacts on learners, resulting in lower training costs and effort has improved and their anxiety has been dramatically decreased because of VR-based training. Additionally, they have inquired about employment needs in the city. Needlestick, vehicle shop, and injury prevention, are all terms that come to mind when thinking about injuries.
Medical and stressful situations can both be life-threatening. It is difficult, unnatural, or expensive, to train new doctors to handle medical emergencies before they face them in real life. The failure to properly portray the stress and intensity of real-world trauma management in VR. It offers one-of-a-kind training options. Education, reports, and almost-effective call center training are provided. Reducing surgical durations and the real-world setting improves both physician and patient safety, has beneficial psychological effects on learners, and lowers training costs and efforts, as well as total consequences. Among the 607 participants, 207 males and 155 female medical interns said VR training has dramatically decreased their worry regarding occupational and needlestick injury prevention. VR simulators, according to them, help students cope with tension and anxiety when pursuing medical education, as shown in
Table 6 and
Figure 6.
HYPOTHESIS: 3
Null hypothesis (H0): There is no significant difference between using virtual reality simulators for medical education during COVID-19. The alternate hypothesis (H2): There is a substantial difference between using virtual reality simulators for medical education during COVID-19.
The coefficient of correlation between virtual reality simulators and their use during a pandemic situation during COVID-19 is 0.741 percent, indicating that there are positive connections of 74.1% between virtual reality simulators and their use during COVID-19 on coordination, which is significant at the 1% level. Therefore, the null hypothesis was rejected at a 1% level. Most nations implemented strict lockdown measures to prevent the coronavirus from spreading during the pandemic. Several medical colleges and institutions use virtual reality to enhance traditional teaching methods and medical turning in hospitals. Due to restrictions on in-hospital access, training providers gave students with virtual patient-based instruction, interrogation, and simulated clinical scenarios on a case-by-case basis, all via virtual reality, as represented in
Table 7. Medical students see VR training as a reliable platform for first cleaning evaluation. The VR training is suitable for identifying activity, and its utility in therapy alternatives has been recognized. In addition, students anticipated that the scope of virtual reality instruction would increase apprenticeship at the bedside of a patient.
4.3. Analysis of Result
VR has a positive impact on the level of student involvement. The use of VR has been shown in studies to increase students’ interest and motivation in the study of scientific topics. Students can experience a sense of wonder, cleverness, and power, thanks to augmented reality technology, which may be the primary motivator for their excitement. The ARCS modelling system: a person’s level of interest in the subject at hand, as well as their confidence, sense of accomplishment, and overall contentment (ARCS). VR technology’s impact on students’ desire to learn has been analyzed using the motivational architecture paradigm. Students need to be interested in the architecture, understand its relevance, have faith in it, and feel confident utilizing technology that is based on ARCS for the VR system to be successful. Given that both the VR app and the medical education scale have Cronbach’s coefficient alpha values that are greater than 0.70, this indicates that there is a high degree of internal consistency (V.R. app and medical education model with the only measure of performance). The overall Cronbach alpha value of the VR app and more education dimension is 0.938, which is higher than the cut-off value of 0.70. Confirmatory factor analysis reveals that the VR app and medical education scale used in this investigation (VR and higher education) system with output evaluation alone is a good fit for the data that was collected, as shown in
Table 8. This research presents a five-factor model that, based on the feasibility and statistical significance of relevant parameter estimations, offers a satisfactory explanation of the VR app and medical education framework for the influence of new media technology in learning on higher education. Hopefully, this research will help students have a clearer understanding of the significance of VR simulators technology in medical education and how it impacts student learning. If we take a deeper look at how immersive technology is being used to teach medical students, we may conclude that it has a bright future and room for expansion; as a result, education departments should focus on implementing and standardizing its use.
There was a sample of 670 students participating in the table sample of participants, whose skills were evaluated as a consequence. Research contrasted VR-based therapies with traditional learning, and the aggregate pooled estimate of student performance across all 22 studies indicated a significant increase in post intervention cognitive skill scores for intervention groups when compared with control groups. Refs. [
26,
27,
28] analyzed and contrasted the performance of a variety of VR formats with regard to the learning of cognitive abilities. We were able to integrate the findings of two research that both supported the use of more interactive VR (moderate impact size, poor confidence evidence), as shown in
Table 9.
By enabling students to engage with AR content on their smartphones, augmented reality can make it easier for pupils to learn new information and remember it. Educators will work in conjunction with subject matter specialists to determine the most effective means of incorporating specific qualities into the curriculum. Implementation may be expensive due to the fact that individual schools may not have the necessary funding and rely on subsidies. The new reality of education presents a wealth of opportunities; nevertheless, there is also a significant amount of opportunity for development. When educators use virtual reality (VR) technology in the classroom, they need to exercise caution in order to ensure that students and teachers are able to utilize a range of educational methods. To get the most out of new media and higher education, educators need to become more skilled in the use of technologies such as virtual reality.
