If we think deeply, then we will see. Online Tables (z-table, chi-square, t-dist etc. . And Algebra depends on variables. Hence, we can see graphs for discrete and continuous variables are part of numeric data forms. Categorical data forms are more qualitative. the numbers go on and on until infinity), you have what’s called a continuous variable.

Then you can see the change of the dependent variable. Why not? And stats have a significant role in these changes. He used different colors as unknowns in algebraic equations. We can find variables as single letters in mathematics. These commands are full of pf variables. And the number of students present in a class changes every day. Therefore, if the domain of a continuous variable is the interval (0, 5), then the variable can take any real number value in between 0 and 5. But also many famous scientists used variables in their work. In a nutshell, discrete variables are points plotted on a chart and a continuous variable can be plotted as a line.
