Qualitative Analysis In Nursing

The evidenced-base practice approach in nursing is a standardized method of obtaining and implementing clinical findings, and as professionals, we look thoroughly into research using few essential components necessary to comprehend it adequately. Therefore, it is imperative to familiarize yourself with statistical terminologies like confidence interval and statistical and clinical significance to benefit from the information acquired from a conducted study. First, to discuss the confidence interval (CI), one must apprehend the implications of this measure which could be explained as a process of initially taking a random sample from a population and computing a statistic, such as the mean from the data, while assessing the average of the population. Consequently, that measure prompts us to ask a vital question: How well the sample statistic estimates the underlying population value, or it is only relevant to the original specimen? Subsequently, the confidence interval is a measurement which provides a range of values likely to contain the population parameter of interest.("What are confidence intervals?,"n.d.)
Conversely, 95% CI is the most commonly used, and as Fethney (2010) explains it would indicate that " there is a 95% probability that the interval bounded by lower and upper limit contains 'true' population value" (p.95). With that in mind, the CI reveals the stability of the estimate evidenced by the proximity to the same value if the study was repeated multiple times (Confidence Intervals, n.d.). Furthermore, the purpose of CI is to confirm a clinical significance of a study which translates to the effectiveness of the implemented
