Understanding Different Data Analysis Methods & Models


There are an array of data analysis methods and models used in the business world today. These methods can vary a lot, depending on the desired outcome. So if you are wondering what some major modes of analysing data are, then we have got you covered. In this blog post, we’ll break down some of the most popular methods and models, and explain how they work.

Types of Data Analysis

  • Qualitative Analysis

    In qualitative data analysis, the researcher looks for patterns and themes in the data. They might look at things like body language, tone of voice, and word choice to try to understand what the participants are really saying. It is used to help assess the performance of a company and also aids in making critical decisions in the realm of finance, marketing, public relations and more.

  • Quantitative Analysis

    Quantitative data analysis methods and models are used to examine large data sets in order to identify patterns, trends, and relationships. This method is often used in market research, social science, and statistics.
    There are a variety of different quantitative methods such as descriptive, correlational, experimental and more. So, choosing a particular method will depend on the type of data being analysed and the objectives of the analysis.

  • Text Analysis

    Text analysis is a process of examining or extracting information from text data. It can come in many forms, such as web pages, news sources, emails, tweets, or reviews. There are many different methods and models that can be used for text analysis, such as topic modelling, sentiment analysis, text classification, and text clustering.
    – Topic modelling is a method of identifying the main topics or themes in a collection of text data. This can be done using a technique called Latent Dirichlet Allocation (LDA).
    – Sentiment analysis determines the emotional tone of a piece of text. This can be done using a technique called lexical analysis.
    – Text classification comprises assigning labels or categories to texts. This can be done using a technique called support vector machines (SVM), which is a subset of machine learning.
    – Text clustering is a method of grouping together similar texts. This can be done using a technique called ‘k-means clustering’, wherein different data points are assigned to a particular group, which automatically creates a cluster, as data points are clubbed together based on similar characteristics.

  • Statistical Analysis

    There are a wide variety of statistical analysis methods and models that can be used to analyse data. Two of the most prominent ones are descriptive statistics and inferential statistics.
    – Descriptive statistics are used to summarise data. It basically describes the main features of a data set, such as the mean, median, mode, and range. This method can also be used to calculate measures of association, such as correlation and regression.
    – Inferential statistics is a data analysis method, used to make predictions or inferences about a population based on a sample. They can be used to estimate population parameters, such as means, proportions, and variances. Inferential statistics can also be used to test hypotheses about relationships between variables.

  • Diagnostic Analysis

    This type of analysis looks at past data to find trends and relationships between different variables. It can be used to predict future events or behaviours and to recommend solutions to problems. Basically, it is a more advanced method of statistical analysis, where the anomalies are identified, studied in depth, and a solution is identified for the said anomaly.

  • Predictive Analysis

    Predictive analysis is a type of data analysis that uses historical data to predict future outcomes. This type of analysis can be used to identify trends, develop forecasts, and make decisions about resource allocation.
    By understanding past trends and using them to predict future outcomes, businesses can allocate resources more effectively and plan for potential problems.

  • Prescriptive Analysis

    Prescriptive data analysis directly follows predictive analysis. This method aims to explain why certain outcomes occurred and how those outcomes can be replicated in the future. These methods include predictive modelling, causal inference, and experiment design.
