Two groups of students were tested to compare their speed working on math problems. Each group was given the same problems: one group with calculators and the other group without calculators.

What is the:
- **Independent variable**
- **Dependent variable**
- **Constant variable**

Asked by Ashlyn11

Answer (3)

The independent variable is the presence or absence of calculators
The dependent variable is the speed of working through the mathematics problems.
The constant variable is the time given to each set of students to work through the problems as well as the same kind of math problems.
The **dependent **variable is the variable that changes when the **independent **variable is manipulated. The **constant **variable must remain the same throughout the reaction.
In an experiment, a variable is a measurable quantity that changes its value. One variable is manipulated (**independent **variable) and its effect on another variable (**dependent **variable) is observed.
In this case, the presence or absence of calculators ( independent variable) is observed to affect the speed with which students worked through a math problem(**dependent **variable).
In order to make sense from the results of this experiment, the same time must be allotted to each group of students and the same type of problems must be given to both groups of students. These are the **constant **variables.

The independent variable is the calculator
The dependent variable is the speed of solving the problem.
The constant variable is the same set of problem that was assigned to two groups of students.
The dependent variable is the one that is being tested by experimentation. The dependent variable depends on the independent variable.
The independent variable can b changed by the experimenter whereas the constant variable remains unchanged throughout the experiment.

The independent variable is the presence or absence of calculators, the dependent variable is the speed at which students solve math problems, and the constant variables include the type of problems and the time given to solve them. These definitions help illustrate how the experiment is structured and what is being measured. Understanding these concepts is essential for analyzing the results of such experiments.
