It is very important to select the appropriate statistical test during analysis of the study data. Each test is usually relevant in certain circumstances depending on the nature of the study. A wrong test might give a wrong impression of the findings leading to invalid study findings. In my Evidence-Based Project (EBP) regarding the effect of hand hygiene on reduction of respiratory-like illnesses among elementary school children in a span of six months, the Analysis of Variance (ANOVA) statistical test will be most suitable. Srivastava (2019) stated that ANOVA statistical test is used to check if the means of two or more groups are significantly different from each other with time. Repeated measure ANOVA will be the most appropriate since we will be comparing data at the start of the intervention, mid-way during intervention and after the intervention using the same sample (Holt, 2023). Moreover, this test will be useful in testing the hypothesis that hand hygiene is useful in reduction of infections thereby proving that the null hypothesis is wrong (Holt, 2023). The test will provide information regarding the in-group and between-groups variance which should be larger between-groups than in-groups (Holt, 2023). The independent variable in my project will be time with three levels at zero months, three months and six months level. The significant variance between these levels will prove that the intervention has been effective and lack of any variance or minor change will unfortunately not be able to support the hypothesis.
