- 3. Page | 3 INTRODUCTION Our survey focused on a very common chronic disease, which is called Diabetes mellitus, commonly known as diabetes. Diabetes is known to develop due to a high level of blood glucose and some other commonly known symptoms such as excessive thirst and production of large amount of urine. Even though diabetes is a very common disease, not much people know about some facts about it. Through this survey, we had prepared some questions relating to some facts of diabetes, such as the types of diabetes, transmission of diabetes and the death rate of the disease all over the world. We also included some not commonly known facts about diabetes like the sugar level of severe diabetes patients and the fact that which gender is more likely to be diagnose with diabetes. What we want to learn through this survey is the knowledge the people of a certain gender and age towards diabetes, and then analyze the ratio of the answer from our respondents so that we can learn how much the society understands about the lifestyles of diabetes patients. Also, we wanted to compare the results from our respondents to know their thoughts on what they think the patients live like, and their understanding towards the disease.
- 4. Page | 4 OBJECTIVES We had chosen to focus on male respondents for our survey question. So our objectives of the survey is firstly, to test the knowledge of male young adults about diabetes, because people often misunderstood the symptoms of diabetic patients. Secondly is to analyze the difference of how people view diabetic symptoms, as some people look at diabetes as a very severe chronic disease while others think of less severe. Thirdly is to get an accurate result from different people as we have a minimum of 200 targets and so that we could create a fair statistic to compare the results. And lastly is to complete everything and then come to a conclusion of the aim of our survey.
- 5. Page | 5 METHODOLOGY Since we were targeting 200 male young adults for the survey, each of us were responsible to survey 50 male respondents each, and for a fair result each of us surveyed 25 males of aged 21 to 25 and the rest aged 25 to 30. Because the age ranged from 21 to 30, we went to two places for the survey, which was in Taylor’s Lakeside Campus itself and in Sunway Pyramid mall. We spent 3 days of surveying from 6th of November to 8th of November, and then gathered the information together to do the statistics analysis. Zhao Hong (Ben) surveying a male respondent age 21 to 25. This was in Block D Level 4, in front of the classrooms. Zhao Ming surveying a male respondent aged ranged 26 to 30. We met him at Block D Level 4 as well.
- 6. After gathering all the completed survey forms, each of us analyze our own 50 forms and then gathered all the information together to make our statistics analysis for this report. We first discuss with each other about the calculations needed and diagrams to portray the information, and we transfer the information onto the report.

- 21. Page | 21 CONCLUSION In conclusion, we had come up with the statistics analysis of the ratio and mode. We came up with common and uncommon questions and all the questions, where some were to test the respondents’ understanding towards diabetes, while some were about estimating, mostly the numerical questions. There were some questions which were difficult to estimate. More people assumed that male were more likely to be diagnose with diabetes, which had a frequency of 103, whilst for female there is a close frequency of 97. The mode of the ratio of diabetic patients in Malaysia is 2 to 3 out of 10 Malaysians. As the world is more developed and advance, the respondents had assumed that the recent years of 2010 to 2012 has the highest rate of diabetic patients. More people think that financial is a more severe problem when it comes to a diabetic patient’s lifestyle, as they have to visit the doctor more often than normal people. And that lead to questions about the medication fees of the patients every 6 months, and that more people had chosen the answer of RM300 to RM450, which was a more neutral answer of the 5 answers we provided. And for the mode of the 3 percentages questions, were the death rate of 30% to 50%, prevention rate of 30% to 50%, and curing rate of 30% to 40%. All the 3 questions had a mode towards neutral. While for the questions that tests the understanding level of the respondents, firstly is to test them the types of diabetics there is, and the mode is 3 different types. Next is the stage of a human who were more likely to be diagnose with diabetes, and senior citizens got the highest frequency of 110. The mode for transmission of diabetes is high sugar level diet of 102, and secondly comes genetics, of 57. The sugar level of severe diabetic patients were mostly 6 to 8
- 22. mmol/L chosen by the respondents, where mmol/L means millimoles per litre. More respondents think that watching one’s diet is more likely to prevent diagnosis of diabetes. The last question is a question where the respondents can choose more than one answer, which is about the symptoms of diabetes. Most of the answers’ frequency were equally distributed, but the mode of weight gain with a frequency of 61, then comes swelling on arms and legs of 53, and in third place is loss of appetite of 50. After an analysis of this survey, it shows that the understanding level of diabetes of male aged 21 to 30 in total, is fairly high, but there were some respondents who does not really understand the disease. But overall, the responses were mostly accurate about diabetes and fair enough for us to make a comparison. Page | 22
