Anominal variableis another name for acategorical variable.Nominal variables have two or more categories without having any kind of natural order. they are variables with no numeric value, such as occupation or political party affiliation. Another way of thinking about nominal variables is that they...
Nominal datais labelled into mutually exclusive categories within a variable. These categories cannot be ordered in a meaningful way. For example, preferred mode of transportation is a nominal variable, because the data is sorted into categories: car, bus, train, tram, bicycle, etc. ...
A nominal variable uses descriptive categories, but there is no inherent order to them. For instance, popsicle flavors fall into categories of flavor (lemon-lime, grape, blue raspberry, cherry), but there is no order to those flavors. Which one should be first? Other examples of nominal var...
For the following examples, remember that the nominal definition means “names.” Each variable has category names, observations can fit into only one of these groups, and you can’t meaningfully order the groups. Social science research often collects a lot of nominal data in the form of demo...
A pie chart is a graph that shows the relative frequency distribution of anominal variable. A pie chart is a circle that’s divided into one slice for each value. The size of the slices shows their relative frequency. This type of graph can be a good choice when you want to emphasize ...
Categorical variables are of three types: Binary, nominal, and ordinal variables. Numeric Variable The numeric variable is a quantifiable characteristic whose values are numbers (except for numbers which are codes for other categories). Moreover, numeric variables are either continuous or discrete. ...
Here, statistical, logical, or numerical analysis of data is not possible, i.e., a researcher can’t add, subtract or multiply the collected data or conclude that variable 1 is greater than variable 2. Absence of order: Unlike ordinal data, nominal data can also never be assigned a ...
The kind of variable (qualitative or quantitative). The reference class (the overall class of all those things for which a variable makes sense, such as calories for food or color for hair). The procedure used to make the measurement. ...
( b ) On a nominal scale, a variable is divided into two or more categories. The response to a particular question can fall into either group at this level of measurement. The categories are mutually exclusive. Say, for example, that a person cannot have both an A- and an O+ blood ...
A nominal variable is a categorical variable that differs by quality, but whose numerical order could be irrelevant. For instance, asking somebody their favorite color would produce a nominal variable. Asking somebody’s age, on the other hand, would produce an ordinal set of data. Chi-square ...
