It is really scary to be caught up in traffic. It isn’t just traffic; going to religious gatherings, social gatherings, or just sitting on a sofa in a house can be scary for some people. I mean, because an explosive can just go off at anytime.

Although the number of suicide attacks seem to have reduced (well, we can’t quite tell until we see the numbers in very recent times), it is still impossible to neglect that they are still happening. …


A lot of Nigerian graduates hope that they’d be retained after their National Youth Service Corps (NYSC) especially if they served somewhere they’d always dreamed of working before. Some of these people basically just feel their first job after NYSC might be gotten through these places that they have served in via recommendation to some other company, retainment, posting to some other branch of the same company or organisation they served in, or something related. But this isn’t always the case. Most people go to starting afresh in searching for a job and fitting in properly.

**NYSC is a program…


Libraries for Data Science are a lot! Although these libraries are hardly used at the same time, it is important as a data scientist or an aspiring Data Scientist to know which libraries can be used for what purposes in Data Science. Subsequently, you can investigate more if for any reason you have to use them for your projects or practice. I’d be mentioning 25 libraries that are popularly used for data science. While it is important to know these libraries exists, I feel it is important to have an idea as to what functions exists within these libraries. Mentioning…


I remember the first time I heard that term. The way it was said, made me understand that I was supposed to have known it. Of course I played along… Yea, sure EDA… no big deal! But it was sure a big deal. I got to understand what it meant though but I was still pretty much in the dark. I had questions; how far to go? How to go? What am I doing? When should I stop? How should I stop?

Explore- means to investigate systematically, Analysis-means decomposition into components in order to study. These are pretty much closely…

It has been one awesome month under the She Code Africa Mentorship Program. I have been part of the Data Science Cohort 3 Mentees that started on the 1st of October 2020. After this one month, I would say learning has been rigorously beautiful! Mad o ! 😁

When I first saw the learning path, I was a bit frightened but impressed. Like, if I would be able to do all these, it would be super amazing! The introductory meeting I had to the program was really insightful. Being someone that wanted to switch into Data Science from Teaching, my…


There are many libraries in python for data science. One major library is called Matplotlib.

Matplotlib is used for visualizing data. It can be used for animated and static visualization. In most cases, Matplotlib is imported as matplotlib.pyplot. The sub module pyplot is a style function which allows the creation of lines in plot area, labels and so on.

In order to know how to plot more advanced kinds of graphs, it is important to understand how to plot simple graphs.

In using Matplotlib to visualize data, we have to import Matplotlib first.

import matplotlib as plt %matplotlib inline #to…


Probability is an area in math. It is the chance of an event happening. It is represented as a percentage, fraction or decimal and can be applied to diverse areas and practically too. Probability isn’t one of those math concepts you learn and wonder where you’d apply it to. As a matter of fact, intelligent people make decisions daily by checking probabilities directly or indirectly. For example, you could find out what the probability of meeting your friend at home will be if you decide to pay him a surprise visit. In trying to reason that out, you might want…

It is interesting to know that python was not designed specifically for Data Science, but over the years, it has grown to be one of the most powerful programming languages for Data Science. A lot of people who learn python in recent times do so for the purpose of going into Data Science. It might be overwhelming to learn everything in python, basically because of the fact that python was built so widely for different purposes. Selecting areas to study might be confusing as well, however, there are major areas and concepts that would be enough to get one started…

It has been 34 days since I started the 100 days of code challenge and 21 days of the 70-day’s pre-boot camp classes by Data Science Nigeria. I have tried to make sure that my tasks are kept separate and I have succeeded sometimes but not all of the time. When I first started, I was curious. I wanted to see how to create models right away. I wanted to see the real thing. Although after I did, I had to go back to really understand what was going on. I’m guessing some people are as curious as I was/am…


Data analytics, Data mining, Big Data, Machine Learning, Data Wrangling, and all these trending terms might be confusing at first but let’s focus on understanding what Data Science means in general… Your eyes on the prize guys!

It is very important for ‘sanity-sake’ to focus on one thing at a time or at least multi-task intelligently. The good thing about Data Science is that it covers and encompasses many of these popularly used terms already mentioned.

Not to bore you with definitions but Data Science employs traditional, statistical, mathematical, and algorithmic techniques for analysis and predictions.

I used to pretty…
