Descriptive Analytics Definition

Descriptive analytics is the cornerstone of data analytics, offering a fundamental understanding of both past and present data. It entails analysing historical data to uncover patterns, trends, and insights. Essentially, descriptive analytics provides an answer to the fundamental question, What has happened?

Descriptive data analytics is similar to a good detective in that it methodically examines the evidence left behind in the data to tell a story. Data visualisation, summary statistics, and data profiling are used to offer a full picture of the data's characteristics.

But what is descriptive analytics, and how can it help you or your organisation? Let's go a little deeper into the interesting world of data analysis.

Why is Descriptive Analytics Crucial?

One of the most important benefits of descriptive analytics is its capacity to shed light on past data. Businesses can identify what has worked and what hasn't by analysing prior events and trends. This knowledge will be extremely useful in making future choices.

According to Gartner, poor data quality costs organisations an estimated $13 million every year. Descriptive analytics can assist in identifying and addressing data quality concerns, saving time and money.

“Descriptive analytics helps to improve data quality issues.”

How Does Descriptive Analytics Work?

Descriptive analytics examines historical data and uses statistical tools to find patterns and trends. This procedure entails summarising data, making visual representations, and producing reports highlighting critical insights.

Data Visualisation: Seeing the Bigger Picture

Visualising data is an important part of descriptive data analytics. It converts raw data into visual representations such as charts, graphs, and heatmaps, making complex information easier to understand at a glance. This visual storytelling promotes insight-driven communication and supports data-driven decision-making.

Descriptive Analytics Example: Monthly Sales Analysis

Assume you own a store and wish to review your monthly sales for the last year.

  1. Data collection: Compile monthly sales figures.
  2. Data summary: Determine averages, peak and trough months, and total annual sales.
  3. Data visualisation: Make a chart to identify trends.
  4. Insights: Discover:
    • High sales in December,
    • Lower sales in the summer, and
    • Overall growth throughout the year.
  5. Decisions Plan promotions for December, make staff revisions during quiet months, and establish targets for success.

Descriptive analytics provides insights into sales patterns, assisting in decision-making and strategy. Table 1 contains other real-world examples.
