Data analysis is the practice of working with data to get useful information that can then be used to make informed decisions. The role of a data analyst generally includes collecting, cleansing, and interpreting data sets to answer questions and solve problems for a business. Examining these data sets reveals patterns, highlights relationships, or predicts consumer trends, which empowers us to make better and informed decisions.
TYPES OF DATA ANALYTICS
Descriptive analytics summarizes large sets of data clearly and understandably. It provides a current snapshot by identifying trends and patterns of past and current data. It answers questions about what has happened in the past and what is happening now.
Diagnostic analytics focuses on the reasonings behind trends and patterns that are identified in the previous stage, helping to discover the factors for past performance, identify trends, and extract valuable insights that will inform your next steps.
Predictive analytics uses techniques like machine learning and forecasting to determine what is likely to happen in the future.
Prescriptive analytics uses machine learning, algorithms, and business rules to provide specific solutions and recommendations on what to do next to achieve a desired outcome.
DATA ANALYTICS TECHNIQUES
Regression analysis is a technique for calculating the connection between a group of variables. This analytical method investigates the links between independent and dependent variables. aims to uncover patterns and trends by determining how one or more factors can influence the dependent variable. Understanding the relationship between each factor and how it has changed in the past allows you to estimate future results and make better business decisions.
Factor analysis examines variance between connected variables using a smaller set of unstructured variables known as factors. This technique helps to identify the presence of a relationship between a group of variables. This approach reveals new components or variables that shape the interactions between the initial variables.
Cluster analysis searches for structures in a dataset. Cluster analysis aims to sort disparate data points into groups (or clusters) that are both internally homogeneous and outwardly heterogeneous. This suggests that data points in one cluster are distinct from those in another while remaining comparable.
Segmentation Analysis It is a method of categorizing data into sections that have similar traits, interests, and requirements. Many organizations use this strategy to gain a better grasp of their industry and clients. In order to meet their requests, they may develop specialized tactics, products, and goods.
Time series analysis is a statistical tool for identifying patterns and cycles over lengthy time periods. A time series is a set of data points that show the same variable across time, such as weekly sales figures or monthly email newsletter sign-ups. Analysts can forecast future changes in the variable of interest by observing time-related trends.
Monte Carlo Simulation Your decisions may have unexpected consequences. Monte Carlo simulation is a technique for determining potential outcomes from a set of possibilities. The automated system generates many outputs by mixing the same data in different ways each time.
The discriminant analysis highlights features that highlight groupings by employing various measurements on many sets of data. To categorize new items, these measures are used.
Decision tree analysis is a visual representation of the potential risks and advantages of each option you choose. It facilitates decision-making and the selection of the finest solutions for your firm.
Sentiment analysis seeks to understand and categorize the emotions portrayed in textual data. This helps you to discover what your customers think about various aspects of your company, product, or service from a commercial perspective.
Content analysis condenses words and converts them into quantitative data. This process examines the data using themes, concepts, specific words, and so on.
