What is Data Analytics?
Data analytics, or data analysis, involves analyzing or scrutinizing data to draw meaningful and actionable insights. You can draw these insights from just about any data set, including market trends, market research, various statistics, and financial history.
Data analysis is kind of like a puzzle, where data (puzzle pieces) are put together to show you the big picture in the end. However, data analysis is slightly more complicated than that. Data analytics involves cleaning data, analyzing it, and then visualizing it into more understandable information.
What is a Data Analyst?
A data analyst is a professional responsible for gathering, cleaning, and analyzing data. Analysts also use data visualization tools to present this information in a more understandable way. Data analysts usually have strong backgrounds in statistics, mathematics, and even computer science.
The demand for data analysts only continues to grow, thanks to businesses shifting toward data-driven strategies.
How Long Does It Take To Become a Data Analyst?
There’s no single answer. The truth is, the time you take can be different from how others. Consider these key factors:
- Your starting point: Are you starting completely from scratch, or do you have some relevant skills and knowledge to help you pick things up faster? If you’re starting completely from scratch, it may naturally take you much longer to become confident enough in your skills to look for data analyst jobs. Starting from scratch also means you’ll probably have to spend more time learning certain things that others already know, further slowing down your progress.
- Your background: Data analytics requires a knowledge and understanding of mathematics and statistics. If you do not have a background in either, you can still become a data analyst! However, you may take a little longer to pick up concepts, techniques, and lessons that others may pick up more easily.
- Your choice of data analyst education: You have a few options available as you start learning the skills you need for a data analyst career. You can learn entirely on your own through self-study or by enrolling in online courses and bootcamps. Alternatively, you can attend college and earn a degree.
The factors above impact how long it will take you to become a data analyst. It could take as short as a few months, especially if you already have a relevant background and starting point. However, if you’re starting from scratch and going to college to earn a degree in this field, it could take you a few years.
What Do Data Analysts Do?
Companies collect data on every business activity and expense, be it operational costs, sales data, inventory and supply data, and more. But once they have that data, they need to transform it into information that can inform decisions.
Data analysts turn data from customers, products, performance, and costs into valuable insights that guide strategic decision-making. For example, they can help businesses plan for product development and predict which audiences they’ll find the most success with.

Roles and Responsibilities of a Data Analyst
Here’s a breakdown of a data analyst’s duties:
- Collect Data: Analysts collect data from surveys, web analytics, and buying datasets. However, analysts don’t have to collect all of the data themselves — sometimes, businesses have it available for them.
- Identify Data Errors: Analysts correct any data errors, including duplicates. They also identify outliers and anomalies. Furthermore, analysts ensure consistency to maintain accuracy in interpretations, using tools like Microsoft Excel, business intelligence tools, or programming languages.
- Create Models: Data analysts are also often responsible for data modeling, where they design database structures and determine how to store and compare data categories.
- Interpretation: Data analysts then find trends and patterns in processed data to transform it into valuable insights.
- Contextualize: Analysts will then find connections with interpreted data in the greater context of a business, including the overall market and industry trends on local and international levels.
- Presentation: Last but not the least, analysts must then communicate data findings and interpretations to stakeholders, clients, management, and colleagues using graphs, charts, and other tools.
Data Analyst Qualifications
Many data analysts pursue professional certification to gain knowledge of the role and find job opportunities. This might look like a four-year bachelor's degree in math, science, computer science, business, or statistics. Or, it might look like a professional certificate program that allows more flexibility in study. Both offer perks like networking and a more structured education.
But, professional certification and degrees aren’t necessary to become a data analyst.
Data Analyst Skills
Data analysts have easily transferable skills. Meaning that to be a successful data analyst, you don’t necessarily need a degree. However, the following qualifications and knowledge will certainly help you on your path to becoming a data analyst:
