Understanding Research techniques in nursing - Essay Example In addition to that, the nominal level of measurement entails the grouping of cases into categories. On the same note, in this level of measurement, the measure of dispersion draws its basis on the frequency of the distribution which is the particular frequency of cases in each category (Fisher& Marshall, 2009). On the contrary, the other level of measurement in descriptive statistics is the ordinal level. Apparently, this level of measurement entails grouping of cases into several groups like the previous case. However, here unlike the first case, the categories have numerical hierarchies where data in this level of measurement are classified in a hierarchical manner; in other words, starting from the lowest to the highest point for instance marks (Fethney, 2010). Notably, the measures of the dispersion are similar to the nominal level of measurement but they only vary on the arrangement of the data in the groups. Evidently, the role of descriptive statistics is inevitable in the field of nursing; self-efficacy, which is the ability of a nurse to translate research into meaningful evidence in the field of healthcare (Britt, 2009). On that note, through the study of descriptive statistics, a nurse can be able to think critically and reasonably and thus better job performance (Fisher& Marshall, 2009). It is worth noting that, this particular area of study aids in the building of the thinking capacity of an individual and thus the self-efficacy. Apparently, descriptive statistics can be said to at times very persuasive since it is not a very difficult discipline to venture in as compared to other fields for instance science which may require very complex scientific experiments in order to yield a particular result (Fethney, 2010). Although descriptive statistics plays a huge clinical significance, so does the confidence intervals. On the same
