Key Steps in Data Analytics

Analyzing data involves several steps. These steps, from understanding data requirements to organizing and cleaning, contribute to unlocking valuable insights for informed decision-making:

Step 1: Data Requirements Determination:

  • Understanding how data should be categorized or grouped
  • Data can be numerical or categorical
  • Goal is to define the scope of analysis and establish criteria for data collection

Step 2: Data Collection Process:

  • Collecting relevant information from various sources
  • Ensures a comprehensive dataset for meaningful analysis

Step 3: Data Organization:

  • Organizing data systematically for effective analysis
  • Using tools like spreadsheets or statistical software
  • Arranging data to facilitate easy examination

Step 4: Data Cleaning:

  • Cleaning data involves scrubbing and validation
  • Eliminating duplicates, correcting errors, and addressing incompleteness
  • Enhancing the accuracy and reliability of the dataset

What are the 4 main types of data analytics?

Four primary types of data analytics include:

1. Descriptive Analytics:

Descriptive Analytics focuses on summarizing historical data. This indicates that descriptive analytics is focused on comprehending what has previously occurred. It accomplishes this by summarizing and organizing historical data in an easy-to-understand and interpret format.

They frequently incorporate trend analysis, like as sales numbers, website traffic, or customer satisfaction levels over time. It also entails examining performance data including conversion rates, click-through rates, and average order value.

They are used to answer questions about the past, such as:

  • What were our sales figures last quarter?
  • How has our website traffic changed over the past year?
  • What is our average customer satisfaction level?

2. Diagnostic Analytics:

Diagnostic analytics goes beyond descriptive analytics to explore the reasons why something happened. It does this by examining diverse datasets and looking for patterns and correlations.

Examining various datasets to acquire a complete picture of what transpired is common in diagnostic analytics. A retailer, for example, can examine sales data, customer feedback, and marketing campaign data to determine why sales fell in a specific month.

Diagnostic analytics involves formulating hypotheses about the root causes of events. These hypotheses can then be tested using further analysis or experimentation.

3. Predictive Analytics:

Using past data, predictive analytics makes future projections. Finding patterns and trends in data is done by applying machine learning techniques and statistical algorithms. Many different factors, like consumer behavior, sales information, and market trends, can be predicted by using predictive analytics techniques.

Based on historical data, it can predict future events such as customer turnover, demand for new products, or the chance of a natural disaster.

4. Prescriptive Analytics:

Using the information from predictive analytics, prescriptive analytics makes recommendations that can be put into practice. You can accomplish greater outcomes and make wiser judgments with the help of these suggestions.

Prescriptive analytics not only forecasts future events but also makes recommendations for counteractions. This has the potential to assist businesses in making astute decisions regarding the allocation of resources, refining marketing strategies, and enhancing customer support.

Prescriptive analytics has diverse applications, providing recommendations in various fields, such as:

  • Marketing: Which products should we promote? Which channels should we use?
  • Sales: How should we allocate our sales force? How should we price our products?
  • Operations: How should we schedule our production? How should we manage our inventory?
