What is the difference between a manipulated variable and a responding variable in a controlled experiment?

A variable is something which can change, that is have different values.The proper scientific terms for these are: Dependent and Independent variable. The independent variable is the thing that you vary during an experiment. The dependent variable is what changes as a result of that manipulation.A manipulated variable is the variable which you deliberately alter the value of. So, you will know the values of this variable before you do the experiment. This variable is also called the independent variable.A responding variable is the variable which you have to measure to get your results. So, you do not know the values of this variable until you measure it. This is also called the dependent variable.For example, to find out if your heart rate depends on exercise, you could do different amounts of exercise (the manipulated variable) and measure the heart rate (the responding variable).The above answer is well written, so I will just add a couple of examples.The standard linear equation is defined as 'y = mx + b'. y = 4x + 10, for example, could be charted on a Cartesian coordinates graph as a straight line that has a slope of 4 and a y-intercept of 10. In such linear equations, x would be described as the manipulated, or independent variable, while y would be the responding, or dependent variable.In another example suppose you are traveling in a car at 50 miles per hour. How far would you go if you traveled three hours? In this example, x would be the number of hours traveled, and y would be the total distance traveled in miles. The equation would be y = 50x. In this equation, x is the independent variable, and y is the dependent variable. By substituting 3 for x (because the question asked how far would you go in three hours), we can calculate that you would travel 150 miles. So the distance you travel (y) depends upon how long you traveled (x).


How do you know the difference between the dependent and the independent variable?

The independent variable is one that does not depend on the other variable. A dependent variable "depends" on the other variable. Think about the distance traveled by a car over time. You have two variables in that, time and distance. Now think about which depends on the other. Does time depend on distance? No. Time will keep going even if the car stops. Does distance depend on time? Yes. The more time that goes on, the more distance is traveled. So distance is the dependent variable, because it depends on time. Time is the independent variable because it doesn't depend on distance.


What is the difference between a variable and a non variable?

A variable changes. It varies. A non variable does not change. It is constant. For example if I write a mathematical expression such as x + 1, then x is a variable. Its value can be whatever value we choose. However 1 is a non variable. Its value is 1 and never changes from 1. In a scientific experiment a variable would be something that you changed from one test to another. A non variable would be something that remained constant from test to test. As a final example: the speed at which light travels in a vaccum is a constant. It is referred to by the letter c which stands for the universal constant. However, the speed at which your car travels is a variable. It changes.


What does (00) mean in math?

Rate generally refers to the ratio of the change in a dependent variable to the corresponding change in an independent variable. This is a generalization of the concept of speed in everyday life, like the speed of a car on a road. In that case, the position of the car along the road is a function of time, so position is the dependent variable and time is the independent variable. The change in time is the duration of a time interval (like 3:00 p.m. to 3:05 p.m.), while the change in position is the distance the car travels during that interval. The instantaneous rate at a point is the limit of that rate as the intervals of time starting at that point get smaller and smaller (closer and closer to 0) and that is the definition of a derivative.


What is the independent variable if the rental agency charges 13 a day a day and 08 a mile?

There are two independent variables:1). The number of days you keep the car.2). The number of miles you drive it.The dependent variable is: The total cost of the rental.

What is the independent variables in a problem?

Independent variables are the factors that are manipulated or changed by the experimenter in a study or experiment. They are the variables that are believed to have an effect on the dependent variable, which is the outcome being measured. In research, the independent variables are controlled and varied to observe their impact on the dependent variable.

What type of variable is the number of car accidents reported in your city?

Depends, if you're looking for the raw score then you have a continuous ordinal variable. If you have range of number of car accidents, then you have an interval variable.


What is a structure pointer?

A pointer is a variable that holds address information. For example, in C++, say you have a Car class and another class that can access Car. Then, declaring Car *car1 =new Car() creates a pointer to a Car object.. The variable "car1" holds an address location.
