Data Science is an emerging field and there are various career options you can get in the field of Data Science. Now when you say how much budget you should keep in your mind wherein you can get quality training - On this, I would say it depends! It depends on your requirements and the skills that you already acquire. Say you are a working professional, then you have to look into a course that is inclined towards practical training and exposure and to say you are a graduate or a fresher, here you have to learn how the industry works and go through both practical and theoretical exposure.

Moreover, on the monetary terms or the cost of the course, you should consider on few other things as well, like the time that you will invest, commitment, the reliability of the platform or institution that you are getting trained from. In the end, all that matters is quality training.

Like, for example, even if you get into a well-renowned university for a program in Data Science, but you really have no idea with the prerequisites, or if you are not from a programming background, it actually creates difficulty for you to understand the things that will be covered within the course, except for the only thing that you are pursuing the training from a good university, other than that it sums up that you haven't received any knowledge which in turn leads to difficulty in grabbing a job in Data Science.

So, the first thing that I would ask you to go through is the reliability of the institute that you are going to take up the course from. You have to check up the curriculum, whether they meet up the standards of the industry and whether it is updated accordingly. Due to the growing need of Data Scientists, there are plenty of platforms that are establishing every now and then. And many of them would enroll in any of the institutes by either paying lesser fee or a huge fee, whatever fee you pay, check the curriculum. And the reliability of the platform depends on the structure of the curriculum, the mentors, the alumni, and the placement records of the institute.

Now comes the dedication part, before you join for a Data Science program, just clear your thoughts that why do you want to make a career in Data Science, are you really interested in that field or is it just because of all the hype that is created. Data Science is an interesting field and there are lots of learning in that field. If you are dedicated enough, then you can even learn it from a self-paced online training platform. 

Then comes the time part, now that you have decided to make a career in Data Science, be ready to invest a lot of time in it. If you invest a good amount of time on understanding and learning the concepts, you can end up getting trained in 6 months, as 6 months is the minimum time period that you should give yourself for getting trained in Data Science.

These are the basic factors that you have to invest in other than the money!

Now the things that you have to look upon are that, training should never be evaluated in monetary terms, it should always be evaluated on the basis of the quality that they provide in their training. You should always look into the various parameters before selecting a training institute.
These are a few parameters that you must look into:

1. Course curriculum: One should research well on the course structure of some institutes that you are actually interested in, go through the differences of each course and what makes it stand different from the other course. Check whether it includes the fundamentals that are required in Data Science like Python, R, SQL, Statistics, Machine learning algorithms, Hadoop, Spark, etc.
2. The right kind of training: Data Science is an evolving field and it needs real-time solutions. So, you have to look up to a course that provides you real-time exposure that is you get to work on different case studies and projects so that it makes you capable enough to handle the situation in the field. Only understanding the theory and where to use what doesn't help you to sustain in the industry.
3. Assistance Provided: Look for a course that provides you proper assistance, like preparing you for the interviews, you can go through various mock tests and interviews and they even provide you placement assistance. So that it helps you launch your career in Data Science.

I hope these brief insights will help you!
