INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

Statistics Assessment 

Question 1 

Using statistical analysis investigate whether there is evidence that the incidence of cancer in these 2 cohorts is related to tumor stage at diagnosis, tumor size at diagnosis, age of patient or recorded ethnicity of patient. Discuss your results and any significant association found. Explain the nature of any significant association.

Answer

For each question you need to start by stating which test is appropriate and why to answer this question. Then you need to test the assumptions for that test. Then state the null hypothesis for that test and level of statistical significance you are using. Only then do you run the test. Once the test is run, you then discuss the numbers generated from the test and state whether the null hypothesis is proven or disproven and continue to answer the question posed.

Quyestion 1 - You have presented nothing useful in answering question 1. You haven’t chosen or run a test. Go back to the tutorials 1-6 and decide in first place which test is appropriate and then do the test(s) in the same way as we did in the tutorial class.

By keeping in mind the above question researcher has made this hypothesis given below;

State null hypothesis

H1: There is a significant difference between age, ethnicity, tumor stage and tumor size of patients on the basis of area.

Areas  * Metropolitan Tumor stage at diagnosis	3697	91.0%	366	9.0%	4063	100.0%
Areas  * Non-Metropolitan Tumor stage at diagnosis	366	9.0%	3697	91.0%	4063	100.0%
Areas  * Non-Metropolitan Tumor size at diagnosis	339	8.3%	3724	91.7%	4063	100.0%
Areas  * Metropolitan Tumor size at diagnosis	3265	80.4%	798	19.6%	4063	100.0%

 

The above table indicates the total number of sample and percentage. The researcher firstly applied descriptive statistics to measure the number of participants and percentage according to the variables in both cohorts, Metropolitan and non-metropolitan. It’s indicates the total number of respondents in each group, excluded and included as well as their percentage. The below tables also portrays the mean and standard deviations according to different variables on the basis of area.
