Central to evidence-based decision-making is hypothesis testing. It establishes a basis for comparison, which allows one to analyze multiple data sets and determine if the differences that are observed are meaningful or if they are simply the product of random chance. There are many different statistical tests that can be conducted to examine the relationship between the variables and allow the researcher to draw conclusions that are logical and valid (Ranganathan, 2021). Evidence-based findings are integrated into the organizational decision-making process and are incorporated into the strategies of the programs that are planned. The emphasis of the test is hypothesis testing on the differences between two groups.

Hypothesis Generation

Research Question:

Do the mean monthly visits to Rural Clinic 1 and Rural Clinic 2 differ sufficiently to be considered significant?

Null Hypothesis (H₀):

The mean number of monthly visits for Rural Clinic 1 and Rural Clinic 2 is not significantly different.

Mathematical equation: H₀: μ₁ = μ₂

Where:

• μ₁ = mean monthly visits for Rural Clinic 1
• μ₂ = mean monthly visits for Rural Clinic 2

Alternative Hypothesis (H₁):

The average number of monthly visits for Rural Clinic 1 and Rural Clinic 2 is statistically different.

Mathematical equation: H₁: μ₁ ≠ μ₂

Appropriate Statistical Test

The independent samples t-test is the proper statistical test to use when comparing Rural Clinic 1 to Rural Clinic 2. Kent State University (2025) states that the Independent Samples t-Test can be used to determine whether the means of two independent samples are significantly different. The data that are sampled are continuous numerical variables that are count data from two independent, unrelated clinics ( independent, not paired or matched data). The t-test is designed to determine if two independent samples differ significantly in the case where two different groups are compared.

For each group, different statistical values will be computed, and it will be determined if significant difference(s) exist(s) among the groups (National University, 2023). This test will be most useful when comparing two groups on one variable that is measured continuously, and will determine if there is statistical significance for an alpha of .05 to aid the healthcare administrator in making an evidenced-based decision to implement the prenatal program.

Interpretation of the Statistical Results

Results of the independent samples t-test indicate the mean monthly visits of Rural Clinic 1 (M = 124.32, SD = 46.78) and Rural Clinic 2 (M = 145.03, SD = 39.78) are significantly different, t(198) = -3.37, p < .001. No other reports indicate a p-value of 0.000896, which gives evidence that this difference, being 0.1% of the time, is likely to be due to a sampling error. Statistically, the observed effect is not likely to be due to chance (Tenny & Abdelgawad, 2023).

The assumption of no difference in the mean monthly visits of the two rural clinics is not likely; thus, the Rural Clinics are most likely different in the mean monthly visits. It is likely that the Rural Clinics operate differently based on monthly visits, which indicates a performance gap that is worth researching in order to develop an intervention.

Recommendations

It is suggested that the health care system consider the new prenatal program and service use and active engagement of clientele at Rural Clinic 1. This suggestion is based on the statistical analysis and the significant differences in the number of visits to Rural Clinic 1 and Rural Clinic 2. It has been noted that the clinic has improved service and care provision to the patients and that the quality improvement initiatives have been proven to be helpful (Trahan et al., 2025). This action plan should address the needs of Rural Clinic 1 in terms of care provision to the patients and the identified barriers to care (transportation, care provision time, awareness in the community).

A focus should be placed on the improvement of patient outreach by recruiting community health workers, extending clinic hours to allow working mothers to attend, and improving appointment reminders to reduce no-shows (Austin & Qu, 2024). In addition, the optimal practices from Rural Clinic 2 should be identified and implemented at Rural Clinic 1. Monthly performance data should be collected for a period of six months and, during this time, the focus should be placed on each of the defined improvements to service provision. Alternatively, based on the collected data, improvements should be implemented if deemed necessary after three months (Endalamaw et al., 2024).

Conclusion

The hypothesis testing analysis indicated that the two groups differ and that the null hypothesis should be rejected. There are major differences in the performance that should be addressed analytically, as the independent-samples t-test was significant. Suggestions that are informed by the evidence and that are geared towards organizational improvement pinpoint the deficient areas and performance gaps. The improvement and performance gaps will be evaluated and sustained by the evidence-based strategies. There is a continuous need to describe the performance gaps within the context of complex organizational structures in order to make sound business decisions.
