Data Analysis in April
Let's talk about practical matters!
Monthly Datalian Seminar 🎤

April's Datalian Seminar is 🔍
Don't miss Datalian's April seminar, packed with information ranging from profitable sales analysis to cohort analysis frameworks.
“From coming to Avan* to signing a contract for Gran* full option”
Revenue, Paying User Ratio, ARPU, ARPPU, LTV, Up-selling, Cross-selling, Unit Price... Why are there so many technical terms related to sales? Because making sales is the most important thing for a company. We will talk about 'money-making' data analysis, from the basics of sales analysis to Up-selling/Cross-selling.
“Analysis is sluggish? Then try adding a cohort.”
On your first day at work, your team leader suddenly comes to your desk and asks, “We launched a service in January. Can you take a look to see if it’s going well?” He leaves a cup of coffee on your desk. The number of customers is increasing by 1,000 every month, and the average purchase amount per customer is 5,000 won in January, 4,300 won in February, and 4,500 won in March. Team leader, are we… going well?
I recommend this to those who are having these concerns ✅
- I work as a data analyst, but I don't know which analysis method to use for my analysis.
- I want to get a job as a data analyst, but I don't know exactly what this job involves.
- I want to use data in my work, but how do I get started?
📺 In May, we'll talk about how to use visualizations to better present your data.
April Seminar Timeline ⏰

#1 - Data analysis skills that can be used right away in the field
- “From coming to buy Avan* to signing a contract for the Gran* full option” _ Hyejeong
- “Analysis is sluggish? Then try adding a cohort.” _ Sunmi
#2 - Q&A with 4 Data Analysts (Hyejeong, Seonmi, Minju, Bomin )
Expand the pre-questions answered in Part 2
Q1. I'm also curious about CLV utilization ! I know that CLV is predicted and utilized when selecting good customers or measuring marketing costs, but do you know all individual CLVs? Or do you roughly estimate it with average CLV? I'd also like to know the reason for choosing the method! Or do you use another analysis method?
Q2. Domain knowledge is said to be important for data analysts. How does the application of the same analysis technique differ depending on domain knowledge? Is there a way for data analysts to study domain knowledge?
Q3. I feel like it is more difficult to see and analyze various data for retention than for acquisition . I am curious about what data, including cohorts, are recommended for analysis.
Q4. From the perspective of a job seeker, I am curious about how to study analysis methodologies such as Cohort and AARRR.
Q5. How can I develop a business perspective ? Should I take a separate business class? Questions about methods, etc.
Q6. I'm curious about the process of deriving a hypothesis when a problem is given :)
Q7. What are the current trends in analysis techniques ?
Q8. I’m curious about insight derivation skills!
Q9. How can I select important analyses when analyzing data? If I go into too much detail, it feels like TMI (a waste of time), but if I don't go into too much detail, I'm worried that I'll miss out on important things!
Q10. Have you ever regretted your decision to become an analyst?
Q11. I'm curious to know when you feel the most rewarded in your job as a data analyst. :)

If you're curious 👏
What was the most impressive thing you learned during the seminar?

- I liked how you explained it with easy examples, such as Avante, iPhone, Baemin, and KakaoTalk.
- The content definitely contained things that are necessary for practical work, so for me, a new employee in my first year, it felt like I had met a kind senior.
