Variables in Qbasic are divided into two groups. There are numerical variables
and string variables.
This is how you would use a numerical variable:
CLS
INPUT "Enter your first number"; num1
INPUT "Enter your second number"; num2
num3 = num1 * num2
CLS
PRINT "The product of the two numbers is"; num3
END
This example just has the user input 2 variables (num1 and num2)
and store them as numerical variables. Num3 is defined by multiplying
the two user-imputed variables. The text displayed with PRINT
contains normal text with a semi colon to display the result.
This is a string variable example:
CLS
INPUT "What is my name?"; name$
PRINT "Hi I'm"; name$
END
Instead of inputting just the variable name, you add a dollar sign
to signify that it's a string variable. String variables contain letters rather
than numbers. For string variables, you simply put the $ after the variable name every time it's used. Other than that, it's much like a numerical variable.
That's a basic outline of how the variables work. Manipulating the string variables is a different story.

What is the explanation for the two modes of QBASIC?
(1) Immediate mode In this mode, QBASIC performs the command/instruction that we type in immediately after we press the enter key. (2) Program mode In this mode, the instructions/commands we type in are not performed as we type them in, but are first stored in the computer memory as a program. This program can be executed later, at a high speed.
Difference between numeric constants and numeric variables in qbasic?

Is the gender of college students a discrete random variable a continuous random variable or not a random variable?
It is a discrete random variable.
What does variable held constant mean?
The distinction between these two types of variables is whether the variable regress on another variable or not. Like in a linear regression the dependent variable (DV) regresses on the independent variable (IV), meaning that the DV is being predicted by the IV. Within SEM modelling this means that the exogenous variable is the variable that another variable regresses on. Exogenous variables can be recognized in a graphical version of the model, as the variables sending out arrowheads, denoting which variable it is predicting. A variable that regresses on a variable is always an endogenous variable even if this same variable is used as an variable to be regressed on.
What is the the variable you change to see how it will affect the dependent variable?
independent variable
What is the input of a variable called in qbasic?
Variables don't have inputs. A variable is a named memory location where a value may be read or written. You write a variable by assigning a value to it. The value may be obtained from user-input.
