I also work as an analyst, and since the types of work requests are usually quite diverse, I used to spend a considerable amount of time planning analysis tasks, including report writing. However, this course has been very helpful in categorizing my work over the years. Also, the mindset you emphasized really resonated with me, and I was able to reflect on it once again. Although it's brief content, it seems to be a course that makes you think deeply and look back. Thank you for sharing.

What you will gain after the course

Practical Tips for Data Analysts
Data Analyst's Mindset

When you first start data analysis, you'll find yourself pondering questions like these:

I saw the metrics, but what decision should I make with this?
How do you determine whether B looks better in an A/B test because it's a real effect or just a coincidence?
Where should I even start when they tell me to find insights?
I analyzed it, but everyone is having trouble understanding my report

I share experiences and insights as a working data analyst.

I structured data analysis into four types: decision-making, discovery, prediction, and diagnosis, and will share experiences about what problems were solved and how they were approached.
Data analysis is a battle with oneself and a continuous process of trial and error. That's why mindset often shines more than skills and knowledge. I'll share the mindset that data analysts should keep in mind.

I am Gemma, a data analyst who started in mathematics, moved into a developer career, and eventually settled into my current role after studying statistics. In data analysis, the most important thing is identifying novel insights and trends within the overflowing sea of big data. That’s easier said than done, right? However, if you can utilize the right analysis tools and methods, anyone is more than capable of discovering valuable gems. I would like to share these methodologies with all of you.
