Data Analytics for Beginners: What Is It and How to Learn It
The world is full of data-centric businesses these days. Those businesses rely on the expertise of data analysts to keep track of large volumes of data. These in-demand professionals help companies make data-driven decisions.
In this article, you will learn about data analytics for beginners and the skills you’ll need to get started in the field. We also explore education paths for data analytics and give you a few ideas for projects you can add to your portfolio.
What Is Data Analytics?
Data analytics is a set of processes and techniques used to draw actionable insights from raw and undefined data. Simply put, as a data analyst you should be able to make sense of data that an untrained eye can’t interpret. You should also be able to model this data and make it easier for others to understand it.
What Are the Different Types of Data Analysis?
Descriptive Data Analytics
This method of data analysis involves making a description of a dataset over some time. For example, a data analyst working on a digital marketing campaign may make a descriptive report of how the campaign has performed over time. Did certain channels bring conversion? Did sales improve? They will use analytical skills to decide the next step.
Prescriptive Data Analytics
You’ll make suggestions on the best course of action based on data collected and analyzed. If the information from a digital marketing campaign shows that Instagram posts are responsible for 50 percent of the total conversions, the data analyst would suggest that more effort is channeled toward Instagram posts.
Diagnostic Data Analytics
With these analysis skills, the data analyst provides reasons for why certain things happen. If Facebook posts don’t lead to conversions during a campaign, the data analyst would go through the data and figure out why this happened. It could be that the posts didn’t bring in enough sales because they were mainly text and people respond more to visual ads.
Predictive Data Analytics
This involves predicting what will happen in the future based on data that already exists. The data analyst studies the data, finds a pattern, and makes a prediction. For example, a data analyst can look at data and predict that Instagram posts with videos and pictures will lead to more conversations in a digital marketing campaign than those with plain text.
What Are the Stages of the Data Analysis Process?
This is the first stage of data analytics and involves data investigation. As a data analyst, you will be expected to go through the data thoroughly, looking for irregularities and confirming that the data is complete. Data evaluation simply means ensuring that the data you’ll be working with is adequate.
In this step, you’ll be making sense of raw and undefined data using a combination of analytical skills. Data cleansing also involves getting rid of corrupted, inaccurate, and duplicate datasets. Without clean data, database management systems and algorithms can’t be relied upon.
After evaluating and cleaning data, the next stage before the presentation is a summary. You need to summarize large datasets in simple language. No one wants to read long and boring reports with too many complicated words.
When you’re summarizing, make sure that you differentiate facts from opinions and main points from details. Ensure also that there is a logical flow and that the data is easy to read and understand.
