SECI2143-09 KEBARANGKALIAN STATISTIK & ANALISIS DATA (PROBABILITY & STATISTICAL DATA ANALYSIS)

by HENG XING YU

Lecturer: Dr Rozilawati Binti Dollah

There are two main statistic that we learned in this course which are descriptive statistic and inferential statistic. Inferential statistics are used to infer information about the population as a whole from a sample of data collected in an experimental study, whereas descriptive statistics are used to characterise the fundamental characteristics of the data in various ways. This course gives us oppoturnity to learn about the R programming by using Rstudio to analysis the data. For example, one sample test, two sample test, chi-square test, correlation test, regression test and Anova test.

What We Learned?

1. Introduction to Statistic

2. Data Description

3. Descriptive Statistic

4. Probability

5. Hypothesis Testing 

6. Chi-Square Test & Contingency Square Test & Contingency Analysis

7. Correlation and Regression

8. Analysis of Variance (Anova)

REFLECTION FOR PROJECT 2

During doing Project 2, I have learned a lot of skills and gained many new experiences. I learned from this project that data analysis is difficult. We must thoroughly investigate the various types of data to determine which ones are best for analysis. The entire dataset is unavailable if any one of the variables is unavailable. Therefore, my team members and I spent a lot of time discussing datasets. All team members actively express their ideas about the datasets. So, we very smoothly analyze the data at the end. Cooperation and teamwork are very important to produce better work.

At first, I did not know the usefulness of the tests about the inferential statistics. After doing this project, I have a better understanding of tests about the inferential statistics. For example, I strengthened my statistical understanding on hypothesis one sample test, correlation, regression and chi-square test of independence. Other than that, I also learned R programming to analyze the data. These insights are also preparing me for the future and I will undoubtedly use them in the future.

Moreover, this project helped me to improve my leadership skills because it gave me an opportunity to lead my teammates and next time I will be more experienced to lead my teammates. In addition, I also improved my communication skills when doing this project.

In short, I am thankful to Dr. Rozilawati, my lecturer, for providing us with a clear explanation of Project 2 so we could successfully complete our project. Besides, I also very appreciate to cooperation of my team members. Last but not least, I am appreciative of this task because it allowed me to expand my knowledge and develop my skills.
