Clear and structured teaching style

I had the privilege of being trained by Dr. Alvin Ang during a Statistics with Excel course at Tertiary Infotech, and I am truly grateful for the experience. Dr. Alvin has a very clear and structured teaching style that made complex statistical concepts easy to understand, even for someone without a strong background in the subject. He guided us through practical tools such as Excel Analysis ToolPak, covering techniques like hypothesis testing, t-tests, ANOVA, and data visualization in a very hands-on and engaging way. What stood out most was his humor, patience and willingness to ensure every learner have a good time and kept up. He created an environment where asking questions was encouraged, which really helped build my confidence in applying these skills. Thanks to his guidance, I have been able to apply what I learned to my work and continue developing my data analysis skills. I highly recommend Dr. Alvin to anyone looking to build a strong foundation in statistics and data analysis. Thank you again for your guidance and support, Dr. Alvin.

Insightful and knowledgeable trainer

I had the opportunity to attend Dr Alvin Ang's R Tidyverse Data Analytics and Visualization training, and I found him to be a very insightful and knowledgeable trainer. What I appreciated most was how he connected the technical concepts with practical, real-world applications. He went beyond simply teaching R and the Tidyverse tools, and shared valuable insights into how data analytics is actually applied in the industry. As someone who is relatively new to the data analytics field, I found his industry perspectives especially valuable. He gives practical perspectives on the skills, expectations, and continuous learning needed to progress in this field. He also took the time to share additional learning resources and introduce me to a social network of data scientists, giving me opportunities to continue learning even after the training has ended. Overall, I found Dr Alvin to be an engaging, practical, and supportive trainer with strong industry knowledge.

Well-structured, engaging and easy to follow

I had the pleasure of learning R Data Analytics and Visualization under Dr Alvin Ang at Tertiary Infotech. His lessons were well-structured, engaging, and easy to follow, allowing even complex R programming concepts to be understood with confidence. Through a combination of clear explanations, practical examples, and hands-on exercises, he created an enjoyable and highly effective learning experience. Throughout the course, Dr Alvin covered a comprehensive range of topics including data wrangling with the tidyverse, data visualization using ggplot2, data manipulation with dplyr, tidyr and readr, piping with %>%, text mining using wordcloud, and statistical analysis techniques that are highly relevant to real-world data analytics. He was always patient, approachable, and willing to answer questions, ensuring that every participant understood the concepts before moving forward. Beyond the classroom, Dr Alvin generously shared additional learning resources, industry insights, and practical career advice to support our continued learning journey. I would highly recommend Dr Alvin Ang to anyone looking to build a strong foundation in R programming, data analytics, and data visualization. His passion for teaching and depth of knowledge make him an outstanding trainer and mentor.

A luminary in the field of data science

Few can claim to know such a luminary in the field of data science as Dr Alvin Ang. Our correspondence has led me to realize the sheer breadth and depth of the field of data science. Only a true expert like Dr Ang could have revealed to me through his advocacy, teaching, publications, and real world experience how diverse the field truly is. From the very start I was star-struck, first by his academic achievements — a doctorate in Operations Research, a master's in Logistics and a bachelor's in Engineering, all from the world renowned Nanyang Technological University — and then by his experience in industry as well as in academia as a lecturer, trainer, consultant and analyst. He continues to impress and inspire me with his achievements. I highly recommend Dr Ang as the most reputable data scientist that I have been fortunate to know.
