Analysis of Categorical Data
Analysis of categorial data refers to using statistical methods to analyze data grouped into categories. These categories can be nominal (with no inherent order, like hair color) or ordinal (with an inherent order, like education level). The goal of categorial data analysis is to uncover the patterns, relationships, and insights within this data type.
Here are some common ways of analysis of Categorial Data:
Frequency Tables: Create tables to display the data counts or frequencies of different categories.
Crosstabulation: Crosstabulation of two categorical variables is performed to explore the relationship between the two variables.
Chi-Squared Tests: A statistical method used to determine if there is a significant association between two categorical variables.
Contingency Tables: Constructing a two-way table showcases the frequency of occurrence of all unique pairs of values in two columns of attribute data.
Bar Charts and Pie Charts: Categorical data’s Graphical representations help visualize the categories’ distribution.
Odd Ratios: It is a statistical measure used to quantify the association between two categorical variables in case-control studies.
Logistic Regression: A regression analysis used to model the relationship between a categorical dependent variable and one or more categorical or continuous independent variables.
Multiple Correspondence Analysis: A technique used to analyze the relationships among categories of multiple nominal variables.
Analysis of Variance (ANOVA): A set of statistical tests used to compare the means of three or more groups, allowing for the analysis of the effects of categorical variables on continuous outcomes.
Regression Analysis: Modeling the relationship between a continuous outcome and one or more categorical predictors, providing insights into the effects of categorical variables on continuous outcomes.
Categorical Data
Categorical data classifies information into distinct groups or categories, lacking a specific numerical value. It refers to a form of information that can be stored and identified based on their names or labels. Categorical Data is a type of qualitative data that is easily measured numerically.
