What are common independent variables?
Two examples of common independent variables are age and time. They’re independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It’s what changes as a result of the changes to the independent variable.

What is Python variable?
A Python variable is a reserved memory location to store values. In other words, a variable in a python program gives data to the computer for processing.
What are the 4 data types in Python?

- Floating-Point Numbers.
- Complex Numbers.
- Strings. Escape Sequences in Strings. Raw Strings. Triple-Quoted Strings.
- Boolean Type, Boolean Context, and “Truthiness”
- Built-In Functions. Math. Type Conversion. Iterables and Iterators. Composite Data Type. Classes, Attributes, and Inheritance. Input/Output.
How do python variables work?
A Python variable is a symbolic name that is a reference or pointer to an object. Once an object is assigned to a variable, you can refer to the object by that name. Python does not create another object. It simply creates a new symbolic name or reference, m , which points to the same object that n points to.
How can we declare variables in Python?
Python has no command for declaring a variable. A variable is created the moment you first assign a value to it.
How do you declare a variable?
To declare (create) a variable, you will specify the type, leave at least one space, then the name for the variable and end the line with a semicolon ( ; ). Java uses the keyword int for integer, double for a floating point number (a double precision number), and boolean for a Boolean value (true or false).
What is data type and types?
In computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. This data type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored.
What is data type in Python?
Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data. Since everything is an object in Python programming, data types are actually classes and variables are instance (object) of these classes.
What are the four main data types?
Some are used to store numbers, some are used to store text and some are used for much more complicated types of data ….The data types to know are:
- String (or str or text).
- Character (or char).
- Integer (or int).
- Float (or Real).
- Boolean (or bool).

What is a type of data?
At the highest level, two kinds of data exist: quantitative and qualitative. Quantitative data deals with numbers and things you can measure objectively: dimensions such as height, width, and length. But this is just the highest level of data: there are also different types of quantitative and qualitative data.
What are examples of data types?
Common examples of data types
- Boolean (e.g., True or False)
- Character (e.g., a)
- Date (e.g.,
- Double (e.g., 1.308)
- Floating-point number (e.g., 1.234)
- Integer (e.g., 1234)
- Long (e.g.,
- Short (e.g., 0)
What are the two types of data in statistics?
Quantitative or Numerical Data The quantitative data can be classified into two different types based on the data sets. The two different classifications of numerical data are discrete data and continuous data.
What are the examples of data?
Data is the name given to basic facts and entities such as names and numbers. The main examples of data are weights, prices, costs, numbers of items sold, employee names, product names, addresses, tax codes, registration marks etc. Images, sounds, multimedia and animated data as shown.

What are characteristics of information?
Five characteristics of high quality information are accuracy, completeness, consistency, uniqueness, and timeliness. Information needs to be of high quality to be useful and accurate. The information that is input into a data base is presumed to be perfect as well as accurate.
What is a good information?
Good information is that which is used and which creates value. Good information is relevant for its purpose, sufficiently accurate for its purpose, complete enough for the problem, reliable and targeted to the right person.
What are the five parts of an information system?
An information system is essentially made up of five components hardware, software, database, network and people. These five components integrate to perform input, process, output, feedback and control. Hardware consists of input/output device, processor, operating system and media devices.
How do we use information?
Information Uses. People use information to seek meaning in a variety of situations. People also use information to confirm or verify something that they know, to predict what may happen, and to develop or maintain personal relationships.
