Hi, great video! Soon I have to choose a bachelor program keeping in mind that I will probably choose master in data science. I've got 2 options: 1.Mathematics and data analysis 2. Data analysis and engineering (data science) I know that naturally the second option is the better one in terms of a smooth transition. But maybe it is not a huge difference? The first option includes more math oriented topics, the second one - more programming (also in Java for example).I am talking about one of the best uni in my country, the quality of teaching is good when it comes to both options . What would you say and potentially recommend?
@josuebarragan4559
@josuebarragan4559 4 месяца назад
I believe it depends right. Both sound great options and will get your foundational layer covered for the most part. Even within option 1, I can assume you will get basic programming such as R (for statistical analysis) or Python. A better question for ya might be: what you do aspire to use this masters degree or what are your future professional goals? Looking to apply these skills in the industry as a data scientist? Do you intend to pursue a PhD in the future? Is research & the higher theoretic field something you’re passionate about? Based on those questions option 1 sounds more theoretical and could help you further down the line. Option 2 sounds more applied and could help you understand how these skills can be applied in a company. The type of industry niche could play a factor too! Thinking of going into manufacturing? I can tell you first hand that our data scientists often work on creating models but often doing a bit of other roles such as data engineering roles and even operations. Perhaps you want to go into big FAANG companies, then maybe those companies have more of a budget to spend solely on r&d and thus option 1 could be helpful. At the end of the day, both could work for anything because if you do option 1 you could work on some side project that involves more programming! On the contrary, if you go for option 2, you could also do self study on very specific math intensive subjects at your own pace while you learn industry ready skill. Hope my very small 2 cents help in some way shape or form! Best of luck!

I got a 2.2 in CS (admittedly didn't try hard enough) and been thinking of doing a Masters in Data Science but im not 100% on it. I'll be real and say I'm doing the DS masters to make up for the 2.2, despite being more interested in Data Analytics and rather get a job in that but I have doubts that I can land one with a 2.2 in London(I live in London and I have no previous work experience). How hard would you say a Data Science masters is in general? (I know it depends on the Uni) What would you do if you were in my position? I am genuinely lost at the moment and only have a few days to decide if I want to go forward with the DS Masters 😭

It’s definitely possible to become a data scientist without a masters and no experience. I did a 9 week data science Bootcamp and I have a degree in Electronic Engineering. I previously worked in construction as a Quantity Surveyor and I got a job as machine learning scientist 3 months after completing the book camp

I studied maths for my bachelors. A life science background could help, but it really depends on how much stats you know. IMO, the more confident you are with stats, the easier the data science master's will be.

Your opinion could mislead people if I'm honest. Black and white logic doesn't help people see the truth easily. Whether R or Python depends on problems you're solving and the team culture.
@LeonLokk
@LeonLokk Год назад
Thanks for the feedback. I'd add that it also depends on the infrastructure you work with, and since (at least from what I've seen) most companies prefer having a more general infrastructure, Python seems to be the more logical choice for a data science team to use.

No problem! I'd say as a graduate the biggest thing is to make sure you have enough projects on your CV to talk about in the interviews. Try apply to as many companies as possible and really try your best to research each company and their products before beginning the interview process.

Yes, a data science master's will cover the fundamentals. Since you have a maths background, you can pick more programming or data science theory modules if that's what you want to focus on instead.

I've seen people go from an analyst to data scientist in 2 or 3 years. but some people take longer. It really depends on what you're exposed to at work. If there's already a bunch of data scientists that you get to work with, then I'd imagine it'd be much quicker to progress.

@kelverrodrigocontrerassala8899
Good morning Leon, I am a foreigner very enthusiastic about doing a master's degree in data science in the UK with the profile you described. For example, I find it very important that the master's degree is based on Python and I am preparing myself to handle this programming language. However, there are too many masters and universities in the UK, which universities do you suggest? I have a bachelor's degree in economics so I am looking to specialise in data science to use big data in the development of public projects. Glasgow University is my first choice for now, what do you think?
@LeonLokk
@LeonLokk Год назад
It's hard for me to suggest any universities besides my own, as that's the one I studied at. I can only suggest doing your own research on what the course offers and whether it matches with your interests and needs.

I had no work experience during my time at secondary school. The best thing I can suggest (and wish I did) is to do your own projects in your own time and treat them seriously like you would with work experience. Most employers can understand if you don't have any work experience in the beginning, so having a portfolio will make you stand out a lot.
