Delve into the world of data analysis and embark on a dynamic and rewarding career path, especially in an era where data-driven decision-making reigns supreme.
A data analyst is like a Swiss Army knife of the information world and is expected to know the ins and outs of a company or organization’s data to guide informed decisions.
If you are looking for more info on how to start a career as a data analyst—you have come to the right place.
This guide is all about what you will need to become a data analyst, including data analyst degree options, info about what data analysts do all day, and what some potential career paths might look like.
Data Analyst Degree
There are several routes to becoming a data analyst. The first route is to obtain a bachelor’s or a master’s degree in finance, economics, information, mathematics, computer science, bioinformatics, and statistics.
Knowledge of the data analyst domain acquired through education helps understand industry-specific information metrics used to derive key insights. A degree in STEM builds a strong foundation in the qualitative skills needed to become a data analyst.
But a data analyst degree isn’t the only way to launch a career. If you decide to change your career trajectory to become a data analyst and come from a non-traditional background, there are several resources to assist you in finding a job in the field.
Online learning platforms such as Coursera, Udemy, and Edx can be used to assist you in developing the skill sets needed to become a data analyst. There are platforms like Kaggle that help you with a dataset that can be used to get practical hands-on knowledge in using necessary tools and tackling challenges while working with datasets to come up with solutions.
Data science bootcamp training or data analyst certifications are another way you could get into a data analyst role without a formal degree.
Regardless of how you prepare for a career as a data analyst, it is important to keep current on evolving tools and platforms to analyze the data. The career path of a data analyst has diverse forks depending on the employment industry.
It has become common for a data analyst to move into a data scientist role, although this depends on the industry if the option is available. There is an overlap between the roles and responsibilities of a data analyst and a data scientist.
A data scientist is expected to frame the right questions to help business growth and development. In contrast, a data analyst is provided with questions that can be answered through data management and manipulation.
Data scientists need to understand mathematical models, machine learning, and technical skills better than data analysts to deploy their work in a production environment.
How To Become a Data Analyst
As technology changes, a data analyst is expected to keep in touch with the latest software and tools that help in fetching, data wrangling, and describing the datasets.
Traditionally, an analyst’s best friends have been Excel spreadsheets, R and Python programming languages, and SQL. Evolving data systems might also require them to fetch data from streaming outputs from NoSQL databases, file storage objects, and continuous streaming data from Apache Spark, Hadoop (MapReduce), Hive, or cloud servers.
As much as technical skills, the importance of strong domain knowledge cannot be underestimated for this role. An analyst can perform their tasks more efficiently if they understand the domain. This will equip them to ask the right questions while collaborating with the stakeholders and providing detailed answers to their questions.
Depending on the industry, a data analyst may be provided with titles such as bioinformatics analyst, healthcare analyst, fraud analyst, and business operations analyst. A data analyst might be expected to have an educational background or work experience in the respective field of interest.
What is a Data Analyst?
In general, a data analyst is known to wear multiple hats. The roles and responsibilities of data analysts may differ slightly based on the industry sector they work for.
On a typical day, a data analyst will perform the following tasks:
Data Munging
Incoming data collected may not always be perfect. Quantitative data might be incoming into the data system as characters or in string format, causing an issue in calculating basic statistics like mean or standard deviation.
It may have a lot of missing information rendering it infeasible to develop key strategies and insights. It may also have noise or information that may not answer the questions needed for business requirements.
Data munging is one task that takes a majority chunk of an analyst’s time. It is a process of taking in raw data and cleaning it to make it conducive to research.
This process involves many tasks not limited to formatting and filtering variables irrelevant for analysis, coming up with data imputation strategies to work with partial data merging data from two different data sources based on key variables or timestamps, and so on.
Data Exploration, Visualization, and Reporting
Once the data is cleaned, the next task is to perform exploratory analysis on the cleaned data by measuring preliminary statistics and describing the data. An analytical mind is needed for the process of data exploration.
This process helps describe the key features present in the dataset. An example of data exploration would be to describe a demographic variable in a survey population like age categorized by gender and using descriptive statistics to look at mean, median, and outliers.
Creating reports regularly is also one of a data analyst’s responsibilities. This reporting leads to tracking the business’s growth or underlying trends or patterns that can help businesses understand their customers and offer insights and areas of improvement.
A data analyst needs to be creative to present their understanding of data that others can quickly grasp. The data analyst needs to be equipped with data visualization skills to plot outcomes and develop dashboards that help in reporting insight from the data.
Data Governance and Management
While this is a broad scope, a data analyst may be involved in some of the tasks but not all of the tasks related to data governance and management. Some examples of tasks involved in these areas may include developing metadata and data quality check strategies.
This requires an analyst to be detail-oriented and organized. During the exploratory phase, a data analyst may find issues with incoming data and may have to collaborate with data engineers and database administrators in the data modeling process to make the data capturing process more robust and convenient to use.
They may be needed to perform data validation by developing edge cases and collaborating with the developers to check for the correctness of data.
Decision-Making and Predictive Analytics
The ability to collaborate with different teams to understand their requirements and clear communication with the collaborating team is appreciated and valued across the industry where a data analyst is employed.
This also requires reasoning skills on the part of the data analyst to come up with information relevant to making decisions.
Occasionally or within a specific industry, an analyst may be required to have statistical skills to perform predictive analytics and projections for business decisions.
Data Analyst Career Paths
Any organization that makes data-driven decisions needs a data analyst on its team. Industries that hire data analysts include finance, insurance, credit bureaus, market research, public health, other healthcare research, sports management, social media, technology firms, non-profits, government, and security systems. The list continues to grow.
Data analytics has emerged as a transformative force in the modern business landscape, empowering organizations to make informed decisions based on data-driven insights.
Data analysts, the architects of this transformation, play a crucial role in collecting, analyzing, and interpreting data to uncover hidden patterns and trends.
