Data collection is the process of acquiring data from various sources, such as news sites, surveys, social media, and even website cookies. Data scientists must collect data generated from millions of users all over the world. It’s a significant part of the process and requires diligent work.
Data cleaning is the next step after collection. A data scientist scrubs through raw data and categorizes it accordingly. They have to look for inconsistencies and missing data to make sure there are no errors with their analysis. This requires strong attention to detail and technical skills to ensure the data scientist has clean data sets to work from.
After the data is cleaned, the data scientist begins inspecting the information through data analysis. Data analysis is the process of inspecting data closely to find key patterns and trends. To make this information presentable to others, there is a great deal of statistical analysis and visualizations done in this stage. Data analysis highlights the points in need of further analysis. Visualization tools also allow data scientists to note the outliers and explore these further.
Data modeling is the process of analyzing and organizing how data should be updated, collected, and stored. It’s an important aspect of any organization that wants to make use of large amounts of data. A data scientist uses various powerful tools and techniques to understand the best ways to create a data model for a business.
There are various ways to build a model. It could either be through machine learning techniques or statistical modeling. Only after the modeling can a data scientist start deriving insights from it.
Data interpretation is the derivation of insights from a data model. Data scientists must present these insights in a way that stakeholders can understand.
This is when one has to go back to the drawing board. How do the insights answer the questions posed at the beginning of the project? What’s the best way of communicating these insights?
For example, a data scientist could use information about user preferences to recommend products to a user on an e-commerce site.
Data scientists work in every part of the data process, from collecting to organizing, analyzing, and interpreting. Data scientists must provide insights to help organizations come up with strategies to meet their goals.
A data analyst is an entry-level data science job. Data analysts spend most of their days analyzing data and writing recommendations. They work with existing data and provide a summary of sorts that details the company’s performance.
Data engineers work on building data infrastructure and dataset processes that data scientists use for analysis. Think of them as software engineers and data scientists combined. To thrive in the role, you must be fluent in programming languages such as Python, R, Java, and Scala.
The first step is to consider what kind of work you would like to do as a data scientist. There are many applications for data scientists as discussed above. You can be a data analyst or a data engineer. Other roles include machine learning engineers and enterprise architects.
Do you wish to attend a university? Are you more suited for the skill-intensive training provided by coding bootcamps? Or do you perhaps wish to try your luck at self-study?
Articles upon articles have pitted college degrees against bootcamp certifications. In the past, pursuing a computer science degree was the main path toward becoming a data scientist. Over the last few years, another popular option has emerged: coding bootcamps.
Coding bootcamps are intensive programs designed to equip you with the skills you’d need to break into the tech industry. The allure of the bootcamp model lies in its short, immersive, and more affordable structure. Premier bootcamps even offer career support post-program to help you secure a job immediately and thrive in it.
Each path has its benefits and drawbacks. Many have opted to take the best of each method to further their education.
To succeed in a career in data science, you’ll need to put what you learn into practice. Few employers hire data scientists without real-world experience. So, finding ways to build some projects to add to your portfolio is important.
Check out our guide on data science projects for beginners. There, you’ll encounter some basic data science projects, with links to relevant datasets. Once you’ve accomplished these, your next step is to launch your project to the world. Read how to launch your portfolio project online through Career Karma here.
Getting a data science internship is another way to boost your profile. Scour popular job websites, such as Indeed and LinkedIn, for great internship opportunities. If you already have a company in mind, check its website for any internships. Even better, go in person and inquire.
Remember that you’re not the only one on the lookout for some work experience so use all the resources at your disposal. Do you know someone in the company who can add in a referral? Does your school have some kind of a partnership with the company? Most coding bootcamps have employer partnerships that you can leverage for an internship opportunity.
