A set of data involving only one variable is referred to as univariate data. This type of data focuses on a single characteristic or measurement, allowing for analysis of its distribution, central tendency, and variability. Examples include a dataset of students' heights or test scores, where only one attribute is examined. Univariate analysis can help identify patterns or trends within that single variable.
D
A binary variable.
You only change one variable in an investigation because if you change more than one you won't know which change affected the data.

In experimental design there are two variables, the independent variable and the dependent variable. You are allowed manipulate or change one variable to see how that affects results in an experiment you are conducting. Think of it as the variable Ican change. This is the i variable, the independent. The experiment will generate data that responds to these changes. This data is your dependent variable.
A set of data with one variable is a net-graph
D
A binary variable.
You only change one variable in an investigation because if you change more than one you won't know which change affected the data.
One variable data are measurements or recordings of the values of one characteristic of the subjects which are being studied. Two variable data refer to two characteristics. Examples of one variable data: hair colour, or height Examples of two variable data: hair colour and eye colour, or height and mass.
Line graphs are used to display data to show how one variable (the Responding variable) changes in response to another variable (the Manipulated variable).
There are many variable data printing services in the phone book. Variable data printing services are also available at universities, although that usually requires one to be a currently enrolled student.
An algebraic equation with only one variable, such as x, has only one variable. It represents a mathematical relationship between that variable and other terms, without introducing additional unknowns.

Because you want to see how the experimental results change due to only that one variable change. If you used two variables, and the results varied, how would you know which variable contributed more to the change if at all? It can be done this way, but one variable at a time will allow you to make sense of your data much more efficiently.
