How many variables do all formulas have?
There is no limit to the number of variables a formula can have.
Why is redi's experiment on spontaneous generation considered a controlled variable?
Redi showed the need to limit/control outside variables when he covered 1/2 the jars and got different results than the uncovered.
What are the variables in a scientific experiment?
There are 3 different variable. The independent variable is what you will be changing in the experiment and there should only be one. The dependent variable is what you will be measuring or observing. The controlled variable is what you will be keeping the same and there can be more than one. There is no limit on how many controlled variables you can have.
Why is it important to limit the variables in an experiment?
To understand this you need to remember that the independent variable is a condition that you can change, and the dependent variable is the outcome that you see. If you have two independent variables, and you change both during an experiment, how are you going to tell which one caused the change to the outcome? So, you only change one independent variable at a time.
How many variables can a scientist change in an experiment?
Anything that can be changed in any way is a variable. so,,,,,an infinite number. Day, time, heat, light, humidity, speed, what you ate for dinner the Wednesday before you go shopping. So, quite literally, an infinite number. Hope this helps.

Why is it sometimes difficult for ecologists to design controlled expermients?
Ecologists study complex and interconnected natural systems that are influenced by numerous variables. This complexity can make it challenging to isolate and control all relevant factors in an experiment. Additionally, ethical and logistical constraints may limit the ability to manipulate certain variables in a controlled setting.
Why is it sometimes difficult for ecologist to design controlled experiments?
it is difficult to control all variables except the one being tested
What does control mean when your talking about science?
The control is the part of the experiment that is NOT allowed to change. It is put through the same environments changes as the Independent Variable so to limit the environmental effect to the conclusion.
When do you use a normal distribution?
When studying the sum (or average) of a large number of independent variables. A large number is necessary for the Central Limit Theorem to kick in - unless the variables themselves were normally distributed. Independence is critical. If they are not, normality may not be assumed.
How many experimental variables should you have?
It is recommended to only have one experimental variable in a scientific study to properly isolate its effects and draw valid conclusions. Multiple variables can complicate the results and make it difficult to determine which variable is responsible for the observed effects.
