Sunday Quicky #2: Git Bash Tab Completion Setup

Introduction

Right now I’m working away on a bigger post, part of the topic being covered is the use of Git. If you don’t know what Git is follow the link, but basically it helps you to keep track of and manage changes made to files you use as part of a project. If you do any sort of coding on your machine and you’re not currently using version control, you really should consider it, it’s a game changer. There’s even a free course on Udacity to get you started, I did a previous version and it was most definitely worth it.

Some Probability Distribution Problems

Introduction

Over in the Udacity course I’m working my way through (AWS Machine Learning Scholarship Program), I came across my first batch of probability distribution problems. I thought that it was a good jumping off point for the blog in terms of working through their solutions. The first problem below I found to be very difficult to find the answer for. Any of my readers who are seasoned Data Analysts or statisticians will have a smug chuckle when they read it, and I don’t blame them, because the answer is pretty obvious. I will, however, ask you to bear in mind that it is about 20 years since I worked consistently with any type of statistics. I’ve dipped in now and again since then, but it really is a use it or lose it skill. I haven’t been using it, so…

The first batch of problems I came across were in a quiz and were in a multiple choice answer format. I’m going to list out the questions and possible answers first and then walk through the terminology involved and how to solve the problems. You smug chucklers see if you can spot why the answer to question 1 should have been instantaneous.

First Post: An Introduction

Posted on 29 May 20207 June 2020 by Barry Keegan

This is my maiden post so before I get into things I thought I should introduce the reason for this blog. Essentially, I’m looking to drive my career towards Data Analysis (or some associated field), but I don’t currently work at Data Analysis (DA). In my current role a kind of analysis of data does get performed, but it’s not DA as it’s understood when companies are looking for Data Analysts. So I wanted to come up with a platform to demonstrate my passion for and knowledge of DA.

An obvious solution is to develop some sort of portfolio of work that I can point to as evidence that I at least have some chops. Credit where it’s due, I was inspired by a friend who began a blog on the subject he was passionate about in order to have something to point to during interview situations, among other reasons. Thanks to Maciej of osintme.com. And so the idea for this blog was birthed.
