Data Analyst Job description: Roles and Responsibilities
Many companies are now talking about ‘data’ and using it to make decisions, this means that data is becoming the key. To make it easier to see how data is changing the world, just look at how major tech companies, especially social media platforms, are using data.
Statistics predict that we create roughly 2.5 quintillion bytes of data each day. And with the growing popularity of IoT (Internet of Things), this data creation rate will grow even higher and exponentially.
The fast rate at which big data – large volumes of varied data generated – is being churned out has opened new multiple opportunities for companies to generate valuable insights to inform their decision-making.
This ever-growing trend has in turn increased the demand and appetite for skilled data analysts across many industries and professions – think about the medical research world, IoT, Agriculture, Electric vehicle manufacturing, and many more. Data Analysts and Data Scientists are therefore highly sought after and frequently feature in most in-demand jobs and careers of the future.
In simple words, a Data Analyst’s job description is to deal with massive data volumes and glean meaningful insights from them. They do this by interpreting statistical data, translating and simplifying this into useful information and visuals that businesses and organizations can use for critical decision-making. For example, a manufacturing firm will use data to precisely determine which products to make, in what quantities, what markets to enter, which investments to make, or which customers to target by which specific product(s). they also use data to identify and do projections of the weak areas in the business that need to be addressed.
Data Analysts’ tasks and responsibilities:
Here’s a short list of Data Analyst’s duties on a day-to-day basis:
- Identify Data: An analyst will be required to scope the data needed for analysis and the intended purpose or goal of this data.
- Data mining or gathering: Analysts are often required to collect data themselves. This can include targeted channels such as running and conducting surveys, tracking visitor behavior, entry and exit characteristics on a website, or landing page, or buying a specific type of datasets from data collection entities or persons.
- Clean data: From the raw data gathered, an analyst will then clean it by removing duplicates, errors, or outliers. By cleaning this gathered data, an analyst will ensure that they maintain the quality of data in a spreadsheet or workbook or a programming language such as Python to ensure the resultant interpretations won’t be wrong or skewed.
- Model and Analyze data: This entails the creation and design of the structures of a database. Here, an analyst might choose what types of data to collect, store or establish how data categories are related to each other.
- Interpret data: This is almost the last leg of data analysis and is probably the most visible. In this stage, an analyst will interpret the data by finding patterns or trends that will help the stakeholders answer the questions at hand. Here, an analyst is also required to research new ways of making use of available data.
- Presentation: This is the last leg and that involves the less complicated yet most difficult job of documenting and communicating the findings or results of the analysis. It is a very key part of a Data Analyst’s role. Here, he or she will present visualizations – for example, charts and graphs, write reports and explanations of scenarios – and lastly, present information to interested parties in a simple to understand manner. A skilled data analyst not only knows how to untangle data but how to present it as well to any audience without losing them or making it too cumbersome to understand.
Key skills required to become a Data Analyst
Now that we know what a Data Analyst does on a day-to-day basis, let us delve into the key skills for the role. We shall break them into technical and soft skills.
Data Analyst technical and hard skills:
Database tools: A good analyst should be able to use spreadsheets such as Microsoft Excel and database tools such as SQL. Excel or other spreadsheets are good and ubiquitous across industries, while SQL is a necessity used to handle larger sets of data faster and accurately.
Programming languages: It is imperative that a Data Analyst learn a statistical programming language, such as Python or R in order to handle large sets of data and perform complex equations.
Data visualization: This is used as we learned above, that’s in the presentation and visualization of findings in a clear and compelling way. Here, one will use tools such as Tableau, Excel, and Jupyter Notebook among others.
Statistics and math: Data analytics is math and statistics heavy and as such, knowing the workings behind what data tools do in the background of processing your data helps a data analyst produce good work. These skills will also help you catch bugs and errors that may skew your data, and have a better understanding of the results.
Data analyst soft or workplace skills:
Communication: Knowing how to properly communicate your ideas to other people is a skill that will take an analyst far in their career. A good analyst will therefore learn or strive to have strong written and speaking skills.
Industry knowledge: Here, it is very important to know more insights about the industry you work in – for example if it’s Business, Manufacturing, Finance, or Healthcare. This will give you an edge and industry advantage in your work and results in producing better analytics.
Problem-solving: When working with large swathes of data, there are many problems as well as short timelines, demands, and pressure from your managers. A data analyst should therefore have a good insight to identify problems fast and their workarounds. Having the critical thinking skills will enable one to target the right data types, identify the most revealing methods of analysis, and not miss the gaps.
What qualifications do you need to become a Data Analyst?
A Data Analyst does not actually require a degree to qualify. However, one needs to have the right combination of both hard and soft skills to be considered for a role in data analysis. A good project portfolio is a good proof of work done that can increase one’s chances of getting a job.
A good Professional Data Analyst Certification can be a great entry and does not require any prior programming or statistical skills and is supposed to be suitable for all types of learners with or without college degrees. An example is the ALX Data Analyst Nano Degree 3-month programme. It’s actually all you need to get started in your career as a Data analyst.
