SDJosh:

Hi. Can you kindly explain the process of getting the frontpagedate and posteddate. I've been trying to replicate your work but I'm having issues with the dates(the format you used though).
On the front page, there's a link called "latest news", clicking on it takes you to a page where the latest news and their time of appearance on the front page is attached to the news link,that should be the "frontpage date",clicking the news link takes you to the news article's page itself,and the first post's date is the "posteddate".
I'm sure you can work your way around the HTML using this description. smiley

Hello Data Scientists and aspiring Data Scientists i trust you are all good.

Lets try and keep this thread alive.

@Ejiod greetings to you and thanks for creating this thread.

Thanks also for those that have shared useful information here

IMO, Power BI is Python and Excel combined, apart from ML.

initially I learnt PBI using Kiril Eremenko's course on Udemy, he only treated visualisation, in 3days I was done and I felt like what's the hype about PBI since its only Drag and drop... lol
I went back learning python till I was comfortable.

I was making research, then i discovered I could do more with PBI. I went back and got another video on udemy like 5gig content.
mehn this guy broke down PBI in and out.

basically PBI is divided into 3parts, visualisation, Power Query and DAX... with Power query, you can manipulate and query data to taste.
with DAX, you can carry out any data analysis calculation(This is deep).
Formally, when I wanted to do any anything involving datetime analysis and Forecast, I would use Statsmodel's ARIMA in Python, and that could take average of 10lines of serious Code, when I came across PBI, I could forecast with 3-4 clicks... mehn I was stunned.
most people don't know that one can Webscrape with PBI, you can do allota wonders with that monster package.

I would advice everyone to take full advantage of it if you really wanna go deep in Data Analytics.

you can contact me for materials or link to good materials.
peace

Edit:
When it comes to Business Intelligence, it has Data modelling ability where you can link many Datasets together so they interact as one and so many more.

Good day bro, pls I'm kindly direct me to a link on PBI. Kindly treat as urgent.

Gracias!

From your write up, I can deduce that two things are missing in your data analytics armament. First is the theoretical knowledge of data analysis (most guys joke with this always) and the second one is the domain knowledge needed to navigate through any data you are working on. You can't make any meaningful conclusion about datasets without these two.

Now, back to the question. Honestly, a simple google search would have given you the answers to your questions, but I'll still try to break it down according to my own little understanding of data science.

Any data collected in its raw form has no meaning until it is processed according to what the company requires so as to utilize the data solely for decision making purpose (making conclusion), which in turn helps the company to grow. Now, there are two important things here,
1. The company's requirement (i.e why was the data collected in the first place?) - Let me give you a couple of real life examples here:
a. The government wants to know whether a newly developed drug will be effective in the treatment of Covid-19. So they do this by conducting a round of clinical trials on patients willing to participate. Remember why the clinical trials were conducted? To test the effectiveness of the drug.
b. A financial institution (bank for instance) wants to develop an advanced system for detecting fraudulent transactions among their customers. They do this by getting a large record of transactions that have taken place in the past. Again, you remember why they needed the record of past transactions? I hope you are getting the gist by now?

2. Now, let's continue with the second important thing in data analysis process which is the goal/objective of obtaining the data in the first place - to make decisions or conclusion about the data.

Going back to the examples I gave above, the government can conclude whether or not the drug is effective based on the outcome of the clinical trial, the financial institution can spot fraudulent transactions based on the model built with the data collected, a country can project their future population based on the available data and make appropriate policies to address any resulting economic/social challenges, Netflix can recommend movies for you based on your history, this makes you stay glued to them, which eventually generates more revenue for them, YouTube suggests videos for you based on your past activities, you are tempted to watch more which means more money for them.

So what's data analysis in real life all about? Three basic things;
1. Why collecting the data?
2. What conclusion (actionable insights) are we making from the analysis?
3. How does the conclusion affect the growth or otherwise of the company?

The takeaways...

When carrying out any analysis, ask yourself or the client these questions;
1. What is the objective of the analysis?
2. Do we have research questions we are trying to answer?
3. Do we have any research hypothesis (which eventually leads to conclusion) ?

The above are what your visualizations and statistical analysis tell you. The more experienced you are, the more accurate you are likely to get the steps.

I hope you find this useful and grow with it.


Boss you really know much. Please profer any book, PDF or any link to download any material you have read. I will be very really be grateful

Good Day Everyone,

I am new in this data journey. I recently completed the SQL introductory course by CodebyMosh. Is there a place I can get data sets to test my abilities?

I also intend to learn python next, is this wise? Are there any recommendations for courses?

Please assist.

You can also learn data analysis for free from this website

Thanks for sharing, GreenDee. I would like to ask, is the Microsoft Data Analyst Associate certification worth it?

I went online to make research about it but some "HR managers" on quora and Reddit said it's not too relevant.

Ejiod and All, what's your take on this?

Hey guys, so I wanna get a laptop for data analysis. Wanna choose between a 2012 i7 MacBook Pro which I would upgrade and a recent specked up windows machine.

Which would you guys recommend?

Thanks.

If you've got enough data, I could put you through on how to get full udemy courses for free even the paid ones through torrent and even converting the torrent files to normal downloads.

Yes it's not too relevant if you are looking for a job at google or amazon, but it is a plus to your cv as far as naija job is concerned, if you can easily afford it, it's worth it. I'm also considering having it, at least for a start.

Note, IBM data science certification still stands out among others.

Yeah.. Exactly..Its good for a start, especially for ppl that are new to the field, and it's even free so you have nothing to lose,just only to invest your time and data.

No, it's not free. The fee is $80

like I said, IBM's Data science certification is cool, the best so far, and You can also try IIBA's Business Data Analytics Certification if you can afford it, just 575 dolls, highly respected and recognized... but I would advice anyone going for these to have a considerable experience first... if you really wanna climb the larger very fast, it is advisable to carry along PMI's Project Management Professional, with all these in one's bag, the sky is just the starting point.
