This is a very interesting presentation as the final exam of my “Business statistics” class at Yokohama National University in Japan.
My classes are all for international students and this is work of a student from Vietnam.
The students learned how to set a practical goal and how to effectively use some analytical techniques to support the conclusion(s).
The student tried to find out the difference of the students from two different countries, Vietnam and Japanese in terms of GPA and objectives to learn at university.
While the sample size is small and the conclusions are not necessarily surprising, the approach and analysis itself was quite interesting.
My class is not just to teach some academic analytical techniques but to teach how to apply those techniques to meet practical goals.
I would be happy to give my lecture anywhere in the world.
This is an assignment of another class “Business data analysis” at Yokohama National University.
Students are required to develop their own story, supported with the analyzed data.
This is the key skill-set when you apply those analytical techniques to the practical business issues/proposals.
We have already experienced several similar exercises at the class and I am so excited that they will enjoy it and present interesting insights.
Please send me an email if you / your organization would like to try those lessons/lectures.
This was an exercise at my biz data analysis class in Yokohama National University for the international students.
The topic of the class was “Data visualization/illustration”. After learning some basic types of graph such as bar chart, line chart, pie chart, Histogram, scatter diagram etc., they tackled the following question:
Assuming that you are required to effectively illustrate the sales results data and report your conclusion to the boss.
Data is quite simple but not easy to find an effective way to summarize the data.
(1) Determine your final key message to report to boss
(2) Study the best way to summarize the data to fit the message.
In my class, the students discuss thier own outputs on how they can improve it.
Some examples are:
You can compare the results by product to identify the best selling product and where is the hot area.
This is an “area-wise” view with product-wise breakdown. You can identify strategic potential area and which product may fit the market.
This simply shows the ratio by product type. No detail about the area but it delivers which products are selling more in a very simple way.
What is the answer? No single “right answer” here. It all depends on your final message.
This is a good exercise to have practical “data managing” skills which will enhance your business competitiveness.

My business statistics class has started at Yokohama National University.
The first exercise of the class today was making a summary of the customer inquiry data at a shopping mall.
The students (international students from 12 countries) were required to make a brief report of the data with the following consideration:
(1) Which category is the most critical, Gender, Age or type of shop?
(2) At which level do you need aggregate the original data to find the insights effectively?
(3) What is the conclusion rather than calculation results?
You do NOT have to rely on any advanced statistical techniques rather you can use simple tools such as TOTAL, AVERAGE, PERCENTAGE etc.
This is the first step for the students who want to manage business data effectively. They were really excited about the exercise.
Enjoy and study hard!
My business statistics class started at Yokohama National Univerisy for the international students from all over the world.
Just to explain some basics for the new students, I was struggling to show the level of aggregation of data in my class.
This is a concept that you need to learn for managing data itself before studying some statsitics.
Today I found the word “granularity”.
I guess it is not that common word even for English speakers but it really fits the concept.
The new semester at Yokohama National University in Japan will begin soon.
Here is an agenda of one of my programs for the international students:
Modeling with statistics and meta-data
The name of the program is a bit strange against my intention but the program is designed for the students who need to make:
(i) a story-based presentation supported by quantitative information (data, data analysis)
(ii) a survey for their business plans/presentations
The class is composed of three parts:
(1) Data management basics
(2) Data analysis techniques
(3) Application exercises (Story-making, survey arrangement)
So excited to start the extremely practical business program in April for the undergraduate students from all over the world!
IoT (Internet of Things) and BI(Business Intelligence) are recent typical buzzwords.
But many business people pay attentions to those new “epoch-making” technologies and keep investing huge amount of money to them.
In my opinion, only technologies or tools(application etc.) may not necessarily help you to resolve your business issues.
But you need a certain level of “analytical skills” to draw a meaningful result from the technology or tools.
In more specific, you need the skill to analyze the outputs which are visualized by a BI tool. A BI tool only gives you an “output” but not” conclusion”.
Likewise, those tools need an input to make an output, which the analyst needs to define.
My training programs improve such analytical skills, which cannot be replaced by any kinds of machines so far. In reality, many of my clients recognized the fact that the technology is just a tool and improved their human skills to reach better performance.
