Why is it important to keep factors other than your independent variable as constants?

If you do not then it is harder to determine whether the changes in your dependent variable are due to differences in independent variables or other variables. However, sometimes it is not possible and good experimental design is required to permit these estimates.

What describes an independent variableWhich of the following describes an independent variable?
for Apex: the variable is an experiment that is manipulated by the scientist.
What is the variation attributable to factors other than the relationship between the independent variables and the explained variable in a regression analysis is represented by?
Regression mean squares
Terms in which the variable factors are the same?
like terms
How do you solve for the indicated variable?
Algebraically manipulate the equation until you have the indicated variable on one side of the equation and all of the other factors on the other side.
What is the coefficient in an equation?
A coefficient is a number paired with a variable. For example, in the equation4x+2x=16, the numbers 4 and 2 would be coefficients.Coefficients are the factors (usually constants) which are multiplied by the variables in each term. For example, in a second-degree polynomial equation,y = ax2 + bx + ca is called the quadratic coefficient, b is the linear coefficient and c is the constant term.
What is any factor that is not allowed to change in an experiment called?
A constant. It is important to ensure that only one factor changes in an experiment (called the independent variable). All other factors need to remain constant.
The relationship between dependent variable and independent variable?
A dependent variable depends on the other factors while an independent variable does not depend on the other factors.
Factors that distort the way the independent variable affects the dependent variable are referred to as?
The factors that distort the way the independent variable affects the dependent variable are referred to as the double-blinds. The factors try to explore the relationship between the dependent and independent variables.
Definition of independent variable and dependat variable?
The independent variable is the variable which you change. It is not changed by any outside factors and so is independent of them.The dependent variable is the variable which is changed by the independent variable changing and which you measure. It is dependent on another variable.
What is an experiment that involves changing one factor and observing its effect on another while keeping all other factors constant?
Controlled experiment. The thing you change is called the independent variable and the constants are the dependent variables. By only changing the independent variable, any results can be attributed to this.
Which of these factors varies due to effects of the factors being tested in a controlled?
the variable
Difference between dependant and independant variable?
dependent: factors of a experiment that scientist observe, and can be changed by the outcome of the independent variable independent: a factor of a experiment that changes because you change it on purpose
What describes an independent variableWhich of the following describes an independent variable?
for Apex: the variable is an experiment that is manipulated by the scientist.
What kind of variable causes the dependent to change?
The independent variable, because it isn't affected by the other factors.
What is a variable that can change?
In an experiment, factors that you change are called independent variables.
Is the independent variable the volume of an object or the mass of an object?
The independent variable of any object depends on the experiment being performed on said object. Do distinguish whether volume or mass is the independent variable, we must first know what the experiment is. Remember that an independent variable does not change when the other factors of an experiment (the dependent variables) do change. An independent variable remains constant.
Things that may change during a experiment are called?
'Variables' are any factors that can be controlled, changed or measured. There are two types: the independent variable and the dependent variable. The independent variable is the condition that you change and the dependent variable is what you are observing. So if you are trying to measure the effect of water on plant growth the water would be the independent variable and the plant growth would be the dependent variable.
