hello house, please how i do data cleaning with my dataset set
Depends on the tools you use,
I use pandas, my main aim of cleaning is to remove missing values and convert all categorical features to numerical features, it depends on your aim with the data.

Good evening House. I've been following this thread for a while now. I'm a lover of Data analysis.

I'm in my final year, an Engineering student. Sooner than later when this pandemic is over, I'll be analysing my project report. I'll be using some statistical analysis like ANOVA table and others to analyse my Data.

Now I will consider myself an intermediate in Python and in Excel. Also I'm a beginner in Pandas. I'm yet to learn Sql, MySql, Matplotlib, seaborne, etc. I only have gotten an intro into Pandas and it's really cool and interesting. I'll soon be done with it.


My Questions are
(1). Which among these; Pandas, Sql, Mysql, Matplotlib, seaborne among others, should I master so as to have a smooth ride in analyzing my project results. Which one also applies ANOVA table??

(2). Which of them aside Pandas (cos I've already started learning Pandas), should I start learning immediately I master Pandas? I'm very conscious of time. I'll really love to use this little time we have to master the more important ones for final year result Analysis. I want to make money from it when school resumes. I want to Master the ones I can so that I can help provide Analysis on other students project results and get paid for it.


Pls I need your Candid responses. Thank you in advance

I think SPSS can effectively handle most data and analysis thrown at it in the academic realm but if you are considering using python scipy and researchpy libraries could also do the same analysis but graphs in SPSS kinda suck so you can learn mathplotlib,seaborn and probably plotly for data visualization if you need something higher.
But overall I think a "theoretical" in-depth knowledge of statistics is the foundation of analysis so you know why and what to do the tools are just there to enhance everything.

Good day sir and thanks for your response. I really appreciate it.

Sir is SPSS a library in Jupyter notebook or it's a software entirely on its own?

Why Is pandas not enough for the job??

Yes it's another software on it's own. Pandas is meant for dataframe wrangling majorly although you can plot with it but if you need to use ANOVA you need the scipy library to do it.

Thanks for this,

I have been trying to scrape a certain car selling website (not like nairaland that load all its details once) but the website is such that as you scroll down it keeps bringing information for new cars. When I tried to scrape it, it only gave me the information for 10 cars alone.
Is there a way to do it that it will give me more cars information.


For pages injected with JavaScript, Selenium is the main tool here. You will need to combine Selenium with infinite scrolling (it will stop once it reaches end of page). A good approach is to scroll to the end of the page first and once everything is loaded in the DOM you can grab them and send them to BeautifulSoup for parsing.

Hello Guys,

As i mentioned earlier. Below is another one from fiverr. The budget is $108. My objective is purely for us to discuss and for people to see real life data science problems that people pay for to be solved for them

I do not even know how to solve this one. I hope out gurus in the house can use it to teach us. Just give us an idea of how to approach it.


>>>>> hi Everybody, I looking for someone for Machine Learning sequence prediction models who are not afraid from numbers & big numbers, So the work will be analyse a file with more then 32000 results of raffles. Each raffle is include 4 cards, Heart, Diamond, Clubs and Leaf. So in each raffle there are result for each cards, means 4 results. Now I think that on this file there is something that return and based on old results new result is coming. There is not pattern or something, you should find something like that. After we success to predict the next raffle, I need it automate, so every time I will load the new CSV it will predict the next results. Do you think you can handle this big file and try to found some algorithm or solution to get high accuracy of the results in next raffle? I've attached here the CSV file with the results. I also know the next raffle result, so let me know if you can predict the results. What I need from you is a "demo" or predict the next raffle results and we compare the results with the real results. Regards.<<<<<

Just put r immediately after the opening bracket such that it reads:
data= pd.ead_csv(r"C:\users blah blah blah...)
That should solve it.

The problem is about sequence predictions. You take an ngram of raffles and you predict the next one. Since you have four classes for each raffle, IMHO you can have four models for each card i.e a model handles all diamonds card history etc.

Once you are done with training the four models, you can then create a function that abstracts the models, takes four cards, distribute them to the models and outputs the predictions.

If you are comfortable using python, you can achieve most of these tasks with it (just learn the relevant libraries)... However, the deeper you go into data analysis/science, the more you discover different tools and what they are best good at. My advice is that whatever tool you are learning, learn it well and practice with it.

For data manipulation, pandas is a must. For visualization, you need matplotlib and/seaborn. I highly recommend plotly for fanciful charts. I don't think you'll be needing SQL for now since you are not going to be interacting with DB.

Wow. I really appreciate your Candid response. I'm already getting to the end of Pandas learning. Tho I'll keep practicing because I can see it's a must.

Now like you said, my next target will be Matplotlib.

Please which one is plotly again ;(
And what is DB( Mongo DB??)

Plotly is similar to matplotlib for plotting charts ...
Just take it one at a time..
DB means DataBase
