The Sample Of 5 Data Points Had A Pearson Correlation Coefficient

depaul university HW 5 MAT 448 Burnett Peter Drogos 2/10/2014 Problems 5.1 and 5.5 in Cody and Smith text, pages 179 and 180, respectively Purpose of problem: Given the following data, write a SAS program and compute the Pearson correlation coefficient between X and Y; X and Z. What is the significance of each? Compute the regression line (Y on X). Y is the dependent variable, X the independent variable. What is the slope and intercept? Are they significantly different from 0? Sample Info and Variables collected: Information was collected from 10 data points that included x, y, and z. SAS routines used: proc corr, proc Summary of results: The sample of 5 data points had a Pearson correlation coefficient between x and y of 0.96509 (p=0.0078), while the Pearson correlation coefficient between x and z is -0.97525 (p=0.0047). These correlation coefficients are both significant. Both sets of data points’ coefficients of determination are 0.931399 and 0.951113, respectively. This means that between x and y, about 93% of the variation in y can be explained by the variation in x, and the about 95% of the variation in z can be explained by the variation in x. The following table summarizes these correlation coefficients. Pearson Correlation Coefficients, N = 5 Prob > |r| under H0: Rho=0 y z x 0.96509 0.0078 -0.97525 0.0047 The slope for the regression line is b=1.52410, while the intercept is a=0.78916. The following table summarizes both parameter estimates. Parameter Estimates Variable DF Parameter Estimate Standard Error t Value Pr > |t| Intercept 1 0.78916 1.25920 0.63 0.5753 x 1 1.52410 0.23882 6.38 0.0078 Summary and concluding remarks: It appears that x and y have a strong positive correlation, suggesting an upward trend- as one variable increases, the other increases as well. x and z appear to have a strong negative correlation; that is, as one variable increases, the...

The Effect Of Early Division Of The Chorda Tympani On Gustatory Function

The effect of early division of the chorda tympani on gustatory function November 22, 2011 by Bruno Kenway, BMedSci, MRCS, DOHNS, Anand Kasbekar, BMedSci, MRCS, DOHNS, Neil Donnelly, MSc, FRCS (ORLHNS), and Patrick Axon, MD, FRCS (ORLHNS) Share on facebook Share on linkedin Share on twitter Share on google More Sharing Services | Reprints Abstract This study was undertaken to assess dysgeusia in patients who have undergone middle ear surgery for chronic suppurative otitis media (CSOM) when the surgeon’s practice was to cleanly divide the chorda tympani without prior manipulation, if it in any way hindered operative access or the aims of surgery. We wanted to determine whether lower rates of taste disturbance might be obtained by early, clean division of the nerve. We followed 110 patients prospectively and asked them to complete a postoperative dysgeusia questionnaire 1 year after surgery. The “cut nerve” group included 81 patients, and the “uncut nerve” group included 29 patients. In the uncut group, the nerve was untouched or underwent minimal handling. In the cut nerve group, 68% of patients had no taste disturbance after surgery; 4% of patients in this group had ongoing symptoms at 1 year postoperatively. In the uncut nerve group, 67% were asymptomatic, while 11% had ongoing taste disturbance at 1 year. Statistical analysis of symptoms beyond 1 year showed a mean difference of 7%, but this is not statistically significant (p = 0.38). These results suggest that early division of the chorda tympani without prior manipulation in patients with chronic suppurative otitis media does not result in higher rates of taste disturbance than in patients with uncut nerves. Indeed rates of taste disturbance in our cut group were lower than in the uncut group, and lower than or comparable to those seen in other studies. Introduction The chorda tympani...

The Conduction Of This Experiment Is Based On A Few Targets, Namely To Carry Out Saponification Reaction

1.0 Abstract The conduction of this experiment is based on a few targets, namely to carry out saponification reaction between Sodium Hydroxide, NaOH and Ethyl Acetate, Et(AC), to determine the effect of residence time to the reaction’s extent of conversion and lastly to evaluate the reaction rate constant of this particular saponification reaction. To achieve these targets, an experiment is finely designed so much so that these targets can be finely met. Such experiment involves using a unit called SOLTEQ-QVF Continuous Stirred Tank Reactor (Model: BP 143), commonly known as CSTR, as well as some common laboratory apparatus for titration process. To put it simply, the two solutions Sodium Hydroxide, NaOH and Ethyl Acetate, Et(Ac) were reacted in the CSTR and the product is then analyse by the method of titration to determine how well did the reaction go. Hence, the experiment was conducted and the results shows that the amount of conversion of Sodium Hydroxide, NaOH increases almost linearly with the increasing of residence time. Further details can be obtained in the results and discussion sections. 2.0 Introduction In the majority of industrial chemical processes, the reactor is the key equipment in which raw materials undergo desired change to form desired products. The design and operation of chemical reactors is essential to the whole success of an industrial process. Reactors can take various form depending on the nature of the feed materials and the products. Understanding the behaviour of reactors is necessary to properly control and handle a raction system. Basically, there are two groups of reactors, batch reactors and continuous flow reactors. The unit used in this experiment, which is SOLTEQ-QVF Continuous Stirred Tank Reactor (Model: BP 143), With this unit, a saponification reaction was conducted by using ethyl acetate and sodium hydroxide among others. 3.0 Aims/Objectives The...

The Bhopal School Of Social Sciences Was Envisioned And Established In 1972 By The Founding Chairman Of The College

The Bhopal School of Social Sciences was envisioned and established in 1972 by the founding chairman of the college, the then Archbishop of Bhopal Dr. Eugene D’Souza, in response to the felt need of the time for a broad based, job oriented curriculum with focus on social service and entrepreneurship. Since its inception it BSSS has evolved into one of the premier educational institutes of Madhya Pradesh shaping the educational landscape of the states. Initially known for its Social Sciences and Management courses, which were indeed a novelty in the 70s and 80s, it grew and diversified to meet the changing needs of time and education, with the introduction of courses in Commerce, Information Technology and Physical Education. The Undergraduate programmes were further developed with the addition of Post Graduate courses in Social Work, English Literature, Commerce and Business Administration. The college offers an International MBA through collaboration with Assumption University, Bangkok in keeping with our sensitivity to global needs. This is a twinning programme where students do part of their studies at BSSS and go on to complete the programme at The Assumption University. The college has introduced two vocational programmes namely M.P.Ed and B.Ed. The approach to these courses is governed by emphasis on practical orientation and exposure. A variety of extension and co curricular activities and programmes aid the learning process and keep the learners active and involved. Enriching teacher student interaction, sharing of responsibilities, ethical development and social awareness help bring about the integrated development of our learners. All through the process of its diversification and expansion, the college never lost sight of the vision of its forefathers and continued to be guided by the spirit of the ideology with which the institute was established – building up a student community which is able to take...
