Nominal data, also known as named data is the type of data used to name variables, while ordinal data is a type of data with a scale or order to it Categorical data is qualitative That is, it describes an event using a string of words rather than numbersCategoricals are a pandas data type corresponding to categorical variables in statistics A categorical variable takes on a limited, and usually fixed, number of possible values ( categories;What are examples of discrete or categorical data?
What Is A Dichotomous Variable
Categorical data type example
Categorical data type example-For example categorical predictors include gender material type and payment method Discrete variables are numeric variables that have a countable number of values between any two values A discrete variable is always numeric For example the number of customer complaints or the number of flawsLet's have another example − Live Demo import pandas as pd cat = cat=pdCategorical( 'a','b','c','a','b','c','d', 'c', 'b', 'a') print cat Its output is as follows − a, b, c, a, b, c, NaN Categories (3, object) c, b, a Here, the second argument signifies the categories

Categorical data can be considered as gathered information that is divided into groups For example, a list of many people with their blood group A, A, B, B, AB, AB,O, O etc in which each of the blood types is a categorical value There can be two kinds of categorical data Nominal data;Examples of categorical variables are race, sex, age group, and educational level While the latter two variables may also be considered in a numerical manner by using exact values for age and highest grade completed, it is often more informative to categorize such variables into a relatively small number of groupsData is labeled categorical if their values describe a quality, grade, level, or other characteristics, such as happy/neutral/sad, low/high, dark/light Categorical data can be Nominal or Ordinal 1 Nominal data Nominal data is a type of categorical data where the order doesn't matter Examples of nominal data Male/Female Countries' names Colors
Categorical variables can be used to represent different types of qualitative data For example Ordinal data represents outcomes for which the order of the groups is relevant Nominal data represent outcomes for which the order of groups does not matter Binary data data with only two possible outcomes Material (Cotton, Polyester) Attributes such as cost, price, quantity are typically integers or floats The key take away is that whether or not a variable is categorical depends on its application Since we only have 3 colors of shirts, then that is a good categorical variableFor example, gender (male/female) is a type of categorical data that is nominal We can only say that males and females are different, but we can't say that one is better or worse than the other Similarly, eye color (brown, blue, green) is a type of categorical data that is also nominal Ordinal Ordinal data are those that can be classified and ranked
Some of the examples of the categorical data are as follows Birthdate Favourite sport School Postcode Travel method to school etcCategorical Data Examples Demographic information entered on surveys, employment and enrollment records, and censuses are collected as categorical data For example, a medical school may analyze statistics about students who apply to their programNominal data This type of

Categorical variables represent types of data which may be divided into groups Examples of categorical variables are race sex age group and educational level See also what rock type is the most common setting for caves formed by dissolution of a rock The most basic levels of measurement are nominal and ordinal data These are types of categorical data that take relatively simplistic measures of a given variable Building on these are interval and ratio data—more complex measures These are both types of numerical data They can be harder to analyze but will, in general, lead to muchLevels in R) Examples are gender, social class, blood type, country affiliation, observation time or rating via Likert scales
