Determine Causal Relationships: Hidden relationships are uncovered by looking at events that might have resulted in the identified anomalies.It requires pulling in data from external sources, thus identifying correlations and determining if they are causal in nature. This step often requires analysts to look for patterns outside the existing data sets. Drill into the Analytics (discovery): Identification of the data sources helps analysts explain the anomalies.Identify anomalies: After performing statistical analysis, analysts are required to identify areas requiring further study as such data raise questions that cannot be answered by looking at the data.The functions of diagnostic analytics fall into three categories: It is also referred to as root cause analysis as it includes processes like data discovery, mining, and drill down and drill through. The diagnostic analysis is a step further to statistical analysis to provide a more in-depth analysis to answer the questions. It includes various tools to perform statistical data analysis such as SAS (Statistical Analysis System), SPSS (Statistical Package for the Social Sciences), Stat soft, and more. It is also called a descriptive analysis. Quantitative data involves descriptive data like surveys and observational data.

Statistical analysis is the technique of performing several statistical operations to quantify the data and apply statistical analysis. Statistics involves data collection, interpretation, and validation. Sometimes people who are not interested in baseball might have trouble understanding it too. Still, if this text is fed to a computer without background knowledge, it would generate several linguistically valid interpretations. For example, humans know that “Red Sox Tames Bull” refers to a baseball match. The ambiguity of human languages is the biggest challenge of text analysis. It is also known as text mining, text analytics, and information extraction. The process consists of slicing and dicing heaps of unstructured, heterogeneous files into easy-to-read, manage and interpret data pieces.

It aims to create structured data out of free and unstructured content. Text analysis is a technique to analyze texts to extract machine-readable facts. The data here present themselves in terms of measurement scales and extend themselves for more statistical manipulation. Generally, this analysis is measured in terms of numbers. Such analysis is usually in the form of texts and narratives, which might also include audio and video representations. This approach mainly answers questions such as ‘why,’ ‘what’ or ‘how.’ Each of these questions is addressed via quantitative techniques such as questionnaires, attitude scaling, standard outcomes, and more. There are various examples where data analysis is used, ranging from transportation, risk and fraud detection, customer interaction, city planning healthcare, web search, digital advertisement, and more.Ĭonsidering the example of healthcare, as we have noticed recently that with the outbreak of the pandemic, Coronavirus hospitals are facing the challenge of coping up with the pressure in treating as many patients as possible, considering data analysis allows to monitor machine and data usage in such scenarios to achieve efficiency gain.īefore diving any more in-depth, make the following pre-requisites for proper Data Analysis: Ensuring data integrity is one of the essential components of data analysis.

Data generation is a continual process this makes data analysis a continuous, iterative process where the collection and performing data analysis simultaneously. These analytical procedures enable us to induce the underlying inference from data by eliminating the unnecessary chaos created by its rest. The systematic application of statistical and logical techniques to describe the data scope, modularize the data structure, condense the data representation, illustrate via images, tables, and graphs, and evaluate statistical inclinations, probability data, and derive meaningful conclusions known as Data Analysis.
