You just nailed it. That my point exactly. People learn and comprehend in different ways. Saying watching videos is not enough to become grounded is totally off the point. I learnt everything I know in Data Science through videos and online Bootcamp. I'm still a work in progress though, Nobody knows it all. But I can tell you for free that I have learnt enough to land me an entry-level data science role. I got a couple of invites for interview for data science jobs in the USA, I couldn't attend because they all want candidates residing in the US even though its remote. The idea was to convert remote workers to full-time after covid subsides.

I just want to enjoin everyone striving hard to learn data science not to give up. There a long road ahead, but appreciate yourself for what you have learnt so far. It is not easy to learn excel alone to mastery level not to talk of SQL and Machine Learning that requires a lot of complex algorithm for building your models. Have a plan, draw a learning schedule for your self and give yourself timelines. Don't try to learn everything at once. Take it one step at a time.

What seems difficult today, will seem like a stroll in the park to you in a couple of months from now with hard work, consistency and dedication. Download different data sets on Kaggle and try to make meaning out of them using what you have learnt so far, be it excel, PowerBI, SQL, TABLEAU or Machine learning.

Believe me, you have what it takes to become a full-fledged data scientist.

Don't be discouraged guys. We will all come back here one day to share our story of how we landed a great job through our skills.

KEEP GRINGING.


Hi, I'd like to send you a DM. How may I contact you? I just want to hear more about your journey. Thanks in anticipation.

Wow! Stumbled upon this thread yesterday and I practically did a vigil on it. I've been interested in data analytics lately as I want to switch careers.

I've been learning excel, python, power bi and sql although it has not been easy combining it with my job but I'm motivated with the stories on this thread.

Thanks Ejiod and everyone that has contributed to this thread

I would like to chat with you about data science . At also new in the process so I really want personnel in the field to talk to, even if it's a group discussion. Thanks

Re: Chronicle Of A Data Scientist/analyst by Hinokami: 6:47pm On Nov 15, 2020
Hi guys.. Just to keep the morale high.. Can we get some testimonies from our bosses here. Who had successfully gotten a job, who had made any significant progress....the realities of the day are quite different.

Unfortunately it goes just beyond learning a skill at the moment. You have to demonstrate such skill, network, build a portfolio amongst others

More suggestions and comments are welcome. Cheers!!!

10 Commandments of Data Science

1. Focus mainly on solving the problem and not on tools, technologies, and models.

2. Data will never be clean or easily available. Data gathering and cleaning will take 80% of your time and effort.

3. Don’t underestimate the power of Excel and SQL - they are still two of the most useful tools for data analysis.

4. Simple models such as Linear or Logistic Regression will be good enough for many problems. You don’t need neural networks to solve every problem.

5. Textbook solutions may not work for most of the practical problems. You will need to try new approaches and innovate as required.

6. Nobody can remember everything. On the job, you can always use Google, Stack Overflow etc.

7. Learn Data Visualisation and develop the ability to explain your key insights in simple terms - such skills will be very useful with non-technical and business stakeholders.

8. Learn PowerPoint and storytelling - people may not appreciate your great work if you can’t convince them with your story.

9. Data Science is evolving rapidly. Please learn continuously, else you may become obsolete soon.

10. Focus mainly on solving the problem and not on tools, technologies, and models.

No 2,3 and 8

I’ve been on a project for sometime now and the only tool I’ve been using majorly so far is Microsoft Office and SQL sense.

I say “sense” because I did a lot of joins, merge and yada yada to pull out data from about 20 excel sheets to create a single refreshable report.

Naija recruiters don't care how good you are, as long as you can't use excel, they trash you!

Jupyter notebook has refused to launch. I've used anaconda navigator it just loads but doesn't launch, anaconda prompt just brings up a prompt telling me to copy a link to my browser.
I need it to open directly in my browser like it should.
o use a Windows and Spyder launches but what I want is jupyter.

Run your system by pressing Windows + R
Then type this
jupyter notebook
anaconda-navigator

The 1st opens jupyter notebook while the 2nd opens anaconda

Thank you for responding.
When I do the first, it brings up a prompt telling me to copy a link to my browser.
The second step opens Anaconda Navigator but when I click on Jupyter notebook it just loads but doesn't open.

Please guys, I need more ideas/processes/options on how to set up a platform to enable a school compute : (1) It's staff payroll (2) Students grade and constantly update it(3)an avenue to send these grade(results) ,other messages to their parent via email.

From what I have looked at so far, I would need to deploy ms Excel and Access.

Can this pass for a data analyst role?

To avoid any complex stuff. Just go to your program files and delete it.
Then reinstall a new anaconda

Stuff like this can be better done using C-sharp. If you know how to write C#, this won't be hard at all. You can easily find codes for this online with just some tweaks and stuff to suit your own task.

Hi everyone, started reading this thread few weeks ago and mehn, I'm pumped�. I've learned Microsoft excel (started way before I discovered this thread), PowerBI and sql. I think I'm okay with the excel, I watched youtube videos(excelisfun) and took leila gharani course on udemy. Now, I'm not too confident in my powerbi, and sql(only watched coding with mosh 3hrs vid on YouTube). Can anyone please recommend tutorials on Powerbi and sql?

for power Bi, I would suggest up and running with power Bi ( a nairalander told me this)
for SQL, I used Ms-sql and postgreSQL database design by krill eremenko

Whatever course you're looking for, just get the name from udemy and append "free" to the course:

E.g:
"Powerbi up and running" + "free"

Google should give you a handful of links to get the course for free if available.

That's the power of research. The more you read, the more information you have at your disposal.

Visual inspection of data distribution (histogram, box plot, q-q plot, p-p plot) is informal, unreliable and does not guarantee that the distribution is normal. Nevertheless, presenting your data visually gives your audience the ability to judge the distribution themselves.

There are many formal tests that can be used for normality aside Shapiro Wilk and K-S tests. However, the former is recommended by many researchers regardless of the sample size, owing to the fact that K-S test is sensitive to extreme values.

You can read more about Normality test here https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3693611/

I'm a final year student of optometry and vision science. No statistics/math. Although, I took some basic math/stat/CS courses in 100/200L
