There are many different data analysis techniques to help you better understand your customers, business efficiency, and research outcomes. Data analysis methods are in high demand. In 2018, the Society for Human Resource Management reported that data analysis was one of the top three missing technical skills in the US workforce.
Whether you want to learn regression analysis for business or descriptive statistics to see the change in different environmental systems, data analysis ideas can help you draw conclusions from data using statistical techniques. This article will show you how to learn data analysis and discuss some common data analysis techniques.
Best Data Analysis Technique Examples
Knowing what data analysis techniques to use can be challenging, but the right data analysis techniques can help you make data-driven decisions in research or business. Below are a few examples.
Regression analysis is a kind of statistical analysis that shows any relationships between a dependent variable and an independent variable. You can use simple linear regression to compare one dependent variable to one independent variable or multiple linear regression to compare one dependent variable to multiple independent variables.
Content analysis is used to identify patterns in written and recorded text. It can illustrate the content’s purpose, messages, and effect. Content analysis can be used to study the impact of political messages, like investigating attitudes about vaccines before and after the start of the COVID-19 pandemic.
Factor analysis is used to decrease the number of variables you need to analyze by finding correlations between groups of factors and conducting your analysis using these factor groups. A dummy variable is used to represent the grouped factors in your analysis. This analysis technique is useful for large and complex data sets and is good at revealing hidden patterns.
Cohort analysis takes a given dataset and breaks it down into smaller related groups, or cohorts, for analysis. Individuals within the cohort share key characteristics. For instance, if you are analyzing how often people use a certain mobile application, you might break them into cohorts based on age.
Discourse analysis uses the social and cultural context of communication to determine the intent of the speaker or writer. Discourse analysis can help uncover the meaning of verbal and nonverbal cues and clarify misunderstandings. It’s a relatively new analysis process.
If you want to learn more about the structure and distribution of a data set, you should use cluster analysis. This analysis technique sorts data points into groups or clusters based on their similarities. Cluster analysis is a good first step to understanding a new data set and can be used to decide which analysis techniques to apply.
Sentiment analysis analyzes textual data to find the emotions behind words. Opinion mining is another term for sentiment analysis, and it uses Natural Language Processing (NLP). This type of analysis is very useful in marketing when you want to understand how a customer feels about a product.
