A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples
of variables. It is called a variable because the value may vary between data units in a population, and may change in value over time. For example; 'income' is a variable that can vary between data units in a population (i.e. the people or businesses being studied may not have the same incomes) and can also vary over time for each data unit (i.e. income can go up or down). What are the types of variables? Show Numeric variables have values that describe a measurable quantity as a number, like 'how many' or 'how much'. Therefore numeric variables are quantitative variables.Numeric variables may be further described as either continuous or discrete:
The data collected for a numeric variable are quantitative data. Categorical variables have values that describe a 'quality' or 'characteristic' of a data unit, like 'what type' or 'which category'. Categorical variables fall into mutually exclusive (in one category or in another) and exhaustive (include all possible options) categories. Therefore, categorical variables are qualitative variables and tend to be represented by a non-numeric value.Categorical variables may be further described as ordinal or nominal:
The data collected for a categorical variable are qualitative data. Types of variables flowchart: Return to Statistical Language HomepageVariable is a quantity or a characteristic that has or more mutually exclusive values or properties of objects or people that can be classified, measured or labeled in different ways. Types of Variables
Characteristics of Variable 1. Capable of assuming several values
representing a certain category. What do you call to characteristics that has two or more mutually exclusive values or properties?A nominal variable with two mutually exclusive categories is sometimes called a dichotomous variable.
What is the two characteristics of variable?A variable is a characteristic that can be measured and that can assume different values. Height, age, income, province or country of birth, grades obtained at school and type of housing are all examples of variables. Variables may be classified into two main categories: categorical and numeric.
What is a variable characteristic?"A variable is a characteristic of a statistical unit being observed that may assume more than one of a set of values to which a numerical measure or a category from a classification can be assigned."
What are the characteristics of independent variable?An independent variable is the variable you manipulate, control, or vary in an experimental study to explore its effects. It's called “independent” because it's not influenced by any other variables in the study. Independent variables are also called: Explanatory variables (they explain an event or outcome)
