Statistics

Toexamine the differences between the two groups the independentt-tests and Chi-square statistics were used. A Chi-square statisticsallowed the researcher to establish whether the proportions observedfor a specific variable was different from the proportions consideredin the hypothesis (Kim &amp Mallory, 2016). On the other hand, theindependent t-test was useful when making a comparison of the meanfor an interval dependent variable that is distributed normally fortwo independent groups.Thetwo tests were appropriate as per the assumptions for differentdifferences in test. The number of variables or group in the studydid influence the selection of the test of difference. Both theintervention and control group influenced the process of selectingthe statistical test of difference. Findings from the independentt-test show a statistical significant difference between the score ofthe mean. The results obtained by the Chi-square, display a racialcomposition within the given sample which is similar to thehypothesized values, where chi-square having three degree of freedom(Wong, Chair, Leung &amp Chan, 2014 Agarwal, 2006).Theresults obtained from this study can be used in the implementation ofBEI. The results will offer aid in evaluating the impact on theoutcomes of patients with limb fractures, who went through surgery. Orthopedic surgery patients experience sleep disorders and anxiety.The limb fractured, which is unexpected could result into triggers ofanxiety. These patients create increased tension due to theirminimized cognitive ability so as to create a full meaning of theevents considered stressful. The results of the study will helporthopedic surgical patients to improve their anxiety and sleeppatterns. The results will show whether there exists a relationshipbetween the education intervention and improvement of anxiety andsleep outcomes.
