If you Google “types of data analysis,” the first few results will explore descriptive, diagnostic, predictive, and prescriptiveanalysis. Why? Because these names are easy to understand and are used a lot in “the real world.” Descriptive analysis is an informational method, diagnostic analysis explains “why” a phenomenon occurs, predictive analysis...
Here’s a picture to visualize the structure and hierarchy of data analysis types, methods, and techniques. If it’s too small you can view the picture in a new tab.Open it to follow along! Note: basic descriptive statistics such as mean, median, and mode, as well as standard deviation, are not shown because most people are already familiar with them...
The highest-level classification of data analysis is quantitative vsqualitative. Quantitative implies numbers while qualitative implies information other than numbers. Quantitative data analysis then splits into mathematical analysis and artificial intelligence (AI) analysis. Mathematical types then branch into descriptive, diagnostic, predictive, ...
Description: Quantitative data analysis is a high-level branch of data analysis that designates methods and techniques concerned with numbers instead of words.Importance: Very high. Quantitative analysis is a must for anyone interesting in becoming or improving as a data analyst.Nature of Data:data treated under quantitative analysis is, quite simply, quantitative. It encompasses all numeric data.Motive:to extract insights. (Note: we’re at the top of the pyramid, this gets more insightful as we move down.)Description: Qualitative data analysis is a high-level branch of data analysis that focuses on text data instead of numeric.Importance: Medium. In general, knowing qualitative data analysis is not common or even necessary for corporate roles. However, for researchers working in social sciences, its importance is very high.Nature of Data:data treated under qualitative analysis is non-numeric. However, as part of the analysis, analysts turn non-numeric data into numbers, at which point many argue it is no longer quali...Motive:to extract insights. (This will be more important as we move down the pyramid.)Description: mathematical data analysis is a subtype of qualitative data analysis that designates methods and techniques based on statistics, algebra, and logical reasoning to extract insights.It s...Importance: Very High. The most widespread methods and techniques fall under mathematical analysis. In fact, it’s so common that many people use “quantitative” and “mathematical” analysis interchan...Nature of Data:numeric. By definition, all data under mathematical analysis are numbers.Motive:to extract measurable insights that can be used to act upon.Description: artificial intelligence and machine learning analyses designate techniques based on the titular skills. They are not traditionally mathematical, but they are quantitative since they us...Importance: Medium. As of today (September 2020), you don’t need to be fluent in AI & ML data analysis to be a great analyst. BUT, if it’s a field that interests you, learn it. Many believe that in...Nature of Data:numeric.Motive:to create calculations that build on themselves in order and extract insights without direct input from a human.Description: descriptive analysis is a subtype of mathematical data analysis that uses methods and techniques to provide information about the size, dispersion, groupings, and behavior of data sets...Importance: Very high.Descriptive analysis is among the most commonly used data analyses in both corporations and research today.Nature of Data:the nature of data under descriptive statistics is sets. A set is simply a collection of numbers that behaves in predictable ways. Data reflects real life, and there are patterns eve...Motive: the motive behind descriptive analysis is to understand how numbers in a set group together, how far apart they are from each other, and how often they occur. As with most statistical analy...Description: diagnostic analysis answers the question “why did it happen?”It is an advanced type of mathematical data analysis that manipulates multiple techniques, but does not own any single one....Importance: Very high. Diagnostics are probably the most important type of data analysis for people who don’t do analysis because they’re valuable to anyone who’s curious. They’re most common in co...Nature of Data: data under diagnostic analysis are data sets. These sets in themselves are not enough under diagnostic analysis. Instead, the analyst must know what’s behind the numbers in order to...Motive:the motive behind diagnostics is to diagnose — to understand why.Description: predictive analysis uses past data to project future data. It’s very often one of the first kinds of analysis new researchers and corporate analysts use because it is intuitive. It is...Importance: Very high.Predictive analysis is critical for any data analyst working in a corporate environment. Companies always want to know what the future will hold — especially for their revenue.Nature of Data: Because past and future imply time, predictive data always includes an element of time. Whether it’s minutes, hours, days, months, or years, we call this time series data. In fact,...Motive: the motive for investigating time series data with predictive analysis is to predict the future in the most analytical way possible.Oct 21, 2024 · Data Analysis Techniques in Research: While various groups, institutions, and professionals may have diverse approaches to data analysis, a universal definition captures its essence. Data analysis involves refining, transforming, and interpreting raw data to derive actionable insights that guide informed decision-making for businesses.
Apr 25, 2024 · Last Updated : 25 Apr, 2024. Data analysis techniques have significantly evolved, providing a comprehensive toolkit for understanding, interpreting, and predicting data patterns. These methods are crucial in extracting actionable insights from data, enabling organizations to make informed decisions. Data Analysis Techniques.
May 10, 2023 · Data analysis is, put simply, the process of discovering useful information by evaluating data. This is done through a process of inspecting, cleaning, transforming, and modeling data using analytical and statistical tools, which we will explore in detail further along in this article.
