As the aim of an experiment is to see what happens when one thing is changed and how it affects something else. If you change two variables, then you don't know which variable is responsible for the change e.g. You are measuring the time it takes for something to fall. If you change both the height and the shape of the object, the time is lengthened. You don't know if the lengethening of time is a result of the change in object shape or height.
Because,Scientist is away of having fun and learning about things all over the world.
"A threat to external validity is an explanation of how you might be wrong in making a generalization."[4] Generally, generalizability is limited when the cause (i.e. the independent variable) depends on other factors; therefore, all threats to external validity interact with the independent variable.
A controlled experiment is an experiment where there are limited or no variables other than the one you are testing for.

local Variable A Local variable is a variable whose scope is limited to the Block of the Subroutine defining it. Private Sub Command1_Click Dim a as integer End Sub Module Level Variable A Module Level variable is a variable whose scope is limited to the Form Module defining it. Public Sub Command1_Click Dim a as integer End Sub Global Level Variable A Global Level variable is a variable whose scope can be limited to the entire project defining it. Private Sub Classjnitialize () Dim a As Integer End Sub

There should be one dependent variables. Depending on the type of research you are doing, the amount of independent variables will change. If you are doing research on a large scale, you will use more independent variables. If it's on a small scale, you will use very little. If you are not able to run your regression it means your sample size is too small or you have too many independent variables.

It was not limited. It consisted of over 2,000 independent city-states spread around the Mediterranean and Black Seas.

For C programming, the use of a static variable has two uses: One reason is to hide the variable from other modules. The scope of the static variable is limited to the compilation unit that it is described in. The second use of a static variable is to keep the value of the variable intact through the entire program execution unit.
