Probability and Statistical Data Analysis in short PSDA is a course that study about statistic and probability. There are two types of statistics such as descriptive and inferential. In our first project, we are using descriptive statistic to present, organize and summarize our data. Data can be differentiate into two types which are primary data and secondary data. The data that we obtain for our Project 1 (A Study on Shopping Preference of UTM Students (Online or Offline)) is a primary data as all the data are collected by ourselves.
To collect the data from respondent, we use Google Form. Thus, by setting and organizing the questions using Google Form, I learned how to relate the types of questions and the types of data need to be collected that mentioned in our task given for instance, nominal, ordinal, interval and ratio. After finalizing the questions, the next things that we need to consider is about the types of graph that used to represent our data. This may include pie chart, bar chart, histogram and so on. This process take much time due to we need to think whether the graph representation is suitable to present our data. At here, we are very appreciate to our lecturer Dr. Chan Weng Howe as he spend his time to explain and give us opinion on our project.
Through this project, I’ve learn how to generate data using R Studio. R Studio is a very useful application especially for a Data Engineering student to summarized all the data needed and run the code to produce a plot. The problem I faced is that the R Tutorial is not enough for me to only refer to it, but I need to explore more on other resources especially on YouTube. Exploration more on YouTube helps me to write and run the code more quick and smooth when doing my project.
Furthermore, because of Movement Control Order (MCO), our presentation cannot be done in class. We can only do it through online or video recorded. So, what I found out is that we can record our video presentation through Power Point! When I heard about this from my teammate, it surprised me as I have use Power Point for so many years from secondary school until university. Thus, this method is chosen for our video presentation.
In conclusion, through Project 1, I have learn a lot of knowledge that I did not know before. I will practice more on this knowledge especially for R Studio because I as a Data Engineering student, statistic and data analysis are the core. I hope that through this subject, PSDA, it will help me to improve myself and become successful Data Engineer in the future.
