Is birthday a categorical variable?
No, date of birth is an ordinal variable. Ordinal variables are similar to categorical variables except that an ordering of the values is possible. With date of birth there are obviously many possible day/month/year "categories" but they are discrete and can clearly be ordered from highest to lowest or vice versa.A categorical variable might be something like animal type. Each animal type fits into a class, but there's no intrinsic ordering of cow, sheep, pig for example.Date of birth itself is not an interval variable either. It doesn't make a lot of sense to talk about "average date of birth" for example. But of course, date of birth can be convertedto an interval variable (i.e. age) simply by subtracting it from another date (e.g. today's date).
Can you give you some examples of categorical data?
Race, Sex, Age group, education level, hair color... Good examples but we might elaborate: we may give categories names. Take for example the variable, hair color. We might name each of the categories like this: red, blonde, black, etc. In this case we would have nominal categorical variables. Further we can think or categorical variables as being ordered such as income level: high, medium, low, very low or socioeconomic class: low, middle, high. These are called ordinal categorical variables because they represent levels and are grouped in levels say from high to low. As another example you might group temperature levels (categories) as cold, cool, warm and hot. So you have nominal categorical variables and ordinal categorical variables. We like to put things into categories. We have classrooms, offices, addresses, etc. We have grade levels in school. What type of categorical variables is "grade"? I graduated from the 3rd grade but my father graduated from the sixth grade. Who has the highest level of education? Why do we categorize things in the world? We group things so we can make sense of the diversity around us. We catgorize animals into species; we even name people when they are born. Is a person's name a variable? Sure is! It's nominal variable. Why is a person's name a variable? Because name changes or varies from person to person. What about the number of people in a classroom. Is that a categorical variable?name of the school
Different types of variables?
In statistics or data management, there are two main types of variables. Each of these types of variables can then be divided into two more types of variables.1. Categorical variableA categorical variable is commonly known as a qualitative variable. Every response can be placed into a category. A response may fit into a specific category (mutually exclusive), or it may fit into a category such as "other" along with other responses (exhaustive). Categorical variables are either nominal or ordinal. A nominal variable is a word that describes a category (i.e. horse, dog, cat) and the order does not matter. An ordinal variable uses categories that have to be placed in an order (i.e. very bad, bad, ok, good, very good).2. Numeric variableA numeric variable is a variable that is expressed by a real number. It is commonly referred to as a quantitative variable. Numeric variables can either be continuous or discrete. A continuous variable is variable that can assume an infinite number of real values (i.e. 2.345....). These variables are often grouped into class intervals. A discrete variable is a variable with a finite number of real values (i.e. shoe size).Grade 12 Data Management class
What is difference between struct variable and class object?
structure variable can access the variable but class object can access the function also
What is difference between an instance variable and a class variable?
An instance variable is typically associated with an object instance of the class whereas class variable is not associated with any object instance. Static variables are referred to as class variables while non-static regular variables are called instance variables. Simply put, you will have as many instances of the instance variable as there are object instances. i.e., if there are 10 instances of an object, you will have 10 instances of that instance variable as well. But, there will be only one instance of the static or class variable. Instance variables are accessed as follows: objname.variableName; Class variables are accessed as follows: ClassName.variableName;
What level of measurement is the variable major?
Yeah that's a question online in your stats class. Read it more carefully. They are asking if Major (area of study) is a quantitative or categorical type of data Answer: Categorical.
Is height measured in inches for each student in a class a categorical variable?
depends where you live. Excluding US, Burma and Liberia, rest of the world uses the metric system.
What is a transient variable?
Transient variable can't be serialize. For example if a variable is declared as transient in a Serializable class and the class is written to an ObjectStream, the val ue of the variable can't be written to the stream instead when the class is retrieved from the ObjectStream the value of the variable becomes null

What do you mean by object adapter explain with an example?
The adapter method is when you create a class which wraps around another (holding that other class as a variable). The adapter class then responds to calls by calling the methods of the held variable.

In oops what is the difference between class variable and variable?
Class Variable is a subset of Variables.
Is the controlled variable the independent variable?
It can be but it is equally possible that the experimenter has absolutely no control over the independent variable. For example, in studying the grades of a class in a school, the pupils' gender may be an independent variable of interest. But the experimenter cannot control that variable.
How do you create an static int as an instance variable?
You create a static integer as an instance variable by declaring it in a class using a statement that consists of the privacy level, then the keywords "static" and "int", and finally, the name of the variable. For example:public class TheAnswerIsHere {public static int example = 0;}will define an int example with initial value 0. The variable is accessed through the statement TheAnswerIsHere.example.
What is the static variable in the class in c?
A static member variable is local to the class rather than to an object of the class.
What is difference between struct variable and class object?
structure variable can access the variable but class object can access the function also
