Data Analytics: The Full Guide

Most people won’t gather valuable insights when looking at lots of raw data.

Data analytics gives meaning to large sets of information, applying statistical and mathematical processes to data to uncover patterns and trends. It uses various tools and technologies to analyze structured and unstructured data, presenting the findings in a way that’s easy to understand.

Data goes through several steps during these processes to ensure it’s properly collected, cleaned, examined, and interpreted. The final stage of data analytics involves visualizing the findings, so businesses can see the results and decide what actions they need to take.

Data analytics allows businesses to utilize their collected data properly. It offers valuable insights that drive data-based decisions to improve operations, efficiency, and competitiveness.

All areas of a company can apply data analytics. It serves many purposes, including market research, financial analysis, risk assessment, fraud detection, optimization, and more.

To better understand data analytics' importance, let’s look at how a SaaS company could benefit from it:

• User behavior analysis: The business could analyze user interactions within the software to understand how they use the product. Applying data analytics to information about the feature usage, user journey, and clickstream data helps the company identify popular features, areas for improvement, or potential bottlenecks. They can use these insights to enhance the customer experience, optimize product features, and prioritize development efforts.
• Customer satisfaction and churn analysis: By tracking customer satisfaction metrics, such as Net Promoter Score (NPS), survey responses, or support tickets, the business can evaluate customer sentiments and identify areas where they are dissatisfied. Data analytics allows the company to address customer concerns, provide personalized support, and reduce churn rates. Analyzing the churn data can also uncover patterns and reasons behind customer cancellations, so the business can take appropriate action to retain customers and improve product offerings.
• Revenue and pricing optimization: Data analytics provides insights into revenue metrics, including average revenue per user (ARPU), customer lifetime value (CLTV), or pricing plans’ performance. The company can optimize pricing strategies, identify upselling or cross-selling opportunities, and analyse the most profitable customer segments. This information helps make informed pricing decisions, maximize revenue, and improve profits.

Without data analytics, businesses would struggle to find meaning in their masses of information. Applying a robust and effective data analytics process helps companies understand their customers, product, and operations to make better business decisions and achieve sustainable growth.

A clear data analytics process is crucial in achieving the best insights and results. These processes and steps can vary depending on the specific business objectives and project requirements and aren’t always linear. They may overlap or require iterations based on the nature of the data, making flexibility and adaptability a key part of data analytics.

However, these stages are the most commonly used if you’re looking for somewhere effective to start.

Requirement gathering

Identifying the project needs, expectations, and specifications is usually the first step of data analytics—often called ‘requirement gathering.’

During this stage, businesses collect the requirements of various stakeholders, including users, clients, business analysts, internal teams, and other relevant parties. This ensures a clear understanding of what each party wishes to discover or achieve with data analytics.

For example, product teams might want to know user drop-off points to know where to focus their optimization efforts. In contrast, marketing teams may wish to understand how customers respond to certain messaging to understand how to personalize their advertising campaigns.

Requirement gathering techniques vary depending on who you want to get information from. It could be as simple as meeting with internal teams and stakeholders to collect views or, if businesses need input from many stakeholders, using questionnaires or surveys to gather structured feedback.

Whatever the approach, collaboration, and communication are key. Requirement gathering is a great way to explore ideas and uncover additional needs you might have yet to consider.

After gathering the stakeholder information, businesses should document and communicate the requirements to the relevant teams. This allows important people within the business to review, verify, and refine the requests, ensuring they align with the business's overall needs and that data analytics can address or achieve them.

Data collection

You can’t perform data analytics without data. A well-executed data collection process lays the foundation for meaningful and reliable data analysis and insights.

Data collection involves gathering relevant and meaningful information from various sources. Businesses use predetermined criteria and objectives (identified during requirement gathering) to select data sources and collection methods.

How a business collects data varies between industries, the type of information they need, and the data origins. There are hundreds of ways and areas to gather this information—businesses might use social media platforms, sensor data, survey responses, user journeys, and more. Selecting the most appropriate method based on the data analytics objectives and available resources is essential.

In some cases, combining multiple methods provides a more comprehensive understanding of the topic. Whichever method a business opts for, it must adhere to legal and ethical considerations, including obtaining necessary permissions, protecting privacy, and ensuring compliance with applicable regulations.

Data cleaning

Once the data is collected and stored, you must prepare it for data analysis.

This involves data cleaning, sometimes called data scrubbing. It’s the process of finding and correcting errors, inconsistencies, and discrepancies in data. Data cleaning improves its quality and reliability and is vital for accurate and meaningful data analytic insights.

It’s an iterative process, meaning the data might undergo multiple cleansing techniques before continuing to the analysis phase.

Some key techniques involved in data cleaning include:

• Handling missing values
• Removing duplicates
• Identifying outliers
• Standardizing formatting and variables
• Resolving inconsistencies and errors
• Addressing data integration issues
• Validating and verifying data

Businesses should document the cleaning steps, including the rationale behind the decisions and changes. This information helps ensure transparency and aids collaboration between data analysts.

Data analysis

We’re moving on to one of the most important data analytics steps—the data analysis stage.

Here, businesses perform various data analysis methods on their cleaned data, often applying several techniques to gather deeper and more valuable insights.

There are many ways to analyze datasets. Different methods work better with different data types and also depend on what questions the business wants to answer.

Data analysts inspect the information using mathematical, statistical, and computational techniques. They might begin by exploring the data to gain a preliminary understanding of its characteristics, using calculated descriptive statistics such as mean, median, mode, standard deviation, or frequency distributions.

Statistical techniques help analyze the relationship and differences between the data. Methods include correlation analysis, regression analysis, hypothesis testing, analysis of variance (ANOVA), or chi-square tests.

Some businesses utilize machine learning for data analysis. Specific algorithms can help analysts discover patterns, classify data, and make predictions. Examples include decision trees, random forests, and neural networks.

If the business has collected much textual data, they’ll probably use natural language processing (NLP) techniques to analyze it. Sentiment analysis, topic modeling, and text categorization are suitable for exploring social media posts, customer reviews, and survey responses.

These are just a handful of data analysis methods and techniques. With more industries adopting machine learning, how we analyze information will likely result in faster and deeper insights in the future.

Data interpretation

It’s no use analyzing data if you can’t make sense of the results. Data interpretation extracts meaning from the findings, highlighting patterns, trends, relationships, and other insights to help draw meaningful conclusions.

It requires analytical skills, domain knowledge, and critical thinking. Analysts will first look at the context of the data, including how it was collected, the sources, any limitations, and other relevant information. They’ll also refer to the business objectives obtained in the requirement gathering stage to understand their needs.

Businesses can use the data analysis results to identify key observations and insights. Narrative and stories assist interpretation and explain the findings. Analysts might link their interpretations to possible causes, underlying mechanisms, or other influencing factors to detail how the results can provide insights for decision-making.

It’s also important to put the findings into perspective during this stage. Businesses must consider the broader implications and significance of their interpretations and determine their practical relevance and potential impact.

While your data analysis is robust and properly conducted, the data interpretation stage is a good chance to acknowledge any limitations and uncertainties. Be transparent about any assumptions made during the interpretation process and address potential alternative explanations or counterarguments.

Data visualization

Sharing and understanding data interpretations is crucial for devising and implementing data-backed decisions. Internal teams and external stakeholders need to visualize the findings clearly and concisely to properly utilize them.

Data visualization helps communicate complex data clearly and intuitively, making recognizing trends, patterns, relationships, and insights easier. Well-designed charts, graphs, maps, and other visual elements allow stakeholders to grasp the results quickly, facilitating meaningful insights and helping drive growth.

Visualization methods vary between businesses and the nature of the findings. Some common types include bar charts, line graphs, scatter plots, pie charts, heat maps, histograms, and treemaps. Businesses should choose the appropriate types that effectively represent the data and the message they want.

You might also consider:

• The visual design—keep it clean, simple, and free from unnecessary decorations
• Visual encoding techniques—to accurately represent the findings
• Highlighting key insights—so viewers are more likely to remember important points
• Making the data interactive—allowing users to explore the data further and examine details
• Storytelling and narrative flow—ensure the visualization is cohesive and logical
• The audience—do you need to adapt the visualizations to suit different audiences and align with their expertise?

These visualizations are largely responsible for informing the overall goal of data analytics (the insights), so making them as effective and clear as possible is integral.

Yes! You’ll most likely come across three types of data analytics—predictive, descriptive, and prescriptive.

Predictive analytics aims to answer questions such as “What is likely to happen?” or “What will be the future outcome?”. It analyzes patterns and relationships within the data to make informed predictions and anticipate trends, usually based on historical data and statistical modeling techniques.

Descriptive analytics also uses historical data but instead focuses on explaining past events. Businesses might use descriptive analytics to see their performance during specific campaigns or understand their product sales.

Prescriptive analytics goes beyond predictions and past findings to provide recommendations and optimal courses of action. It leverages data, mathematical models, optimization techniques, and business rules to determine the best decisions or actions.

Specialized data analytics types can give further insight into a company’s performance or provide more detailed explanations and recommendations. For example, diagnostic analytics focuses on identifying the causes of specific events or outcomes, and exploratory analytics involves discovering new patterns or relationships in data without pre-defined objectives.

Data analytics vs. data analysis: differences explained

Data analysis is a step in the larger data analytics process. As we’ve already discussed, it involves extracting insights and understanding patterns within the data to help draw conclusions.

Data analytics, on the other hand, encompasses a broader range of activities, including data collection, cleaning, interpretation, and visualization. Consider it more akin to data management, using several steps to facilitate decision-making.

Data analytics vs. business intelligence: differences explained

The differences between business intelligence (BI) and data analytics are subtle but still distinct.

Data analytics is a component of BI and involves analyzing data to uncover insights and solve specific problems. BI collects, integrates, analyzes, and presents data to support organizational decision-making.
