What else can I help you with?
How many variables can you have in an expirament?
If you have substantially more than one, you run the risk that your experimental results don't mean what you think they mean. It's always best to eliminate as many variables as it's possible to eliminate, because when you get your results, you have to figure out how much each variable affected them.
Why it is difficult to control extraneous variables in class rooms?
Extraneous variables are any variables other than the independent variable (the experimental variable) that can affect the real-world situation, with multiple uncontrollable variables that can affect the outcome of any experimental manipulation. These include the different personality, intellectual, and motivational qualities of the individual students in the various classes and the nature and quality of their interactions. Added to this is the fact that each class has a different teacher, whose own personal teaching style may influence the outcome. Some of these extraneous variables can be statistically controlled by the use of techniques like analysis of covariance, but this may be of limited value in a small scale intervention.
What is experimental growth function?
Experimental growth function are graphs. The graphs shows the growth of each function.
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
How do you figure out the variables in a science project?
The variable that you change is the independent variable(which you change). This could be the amount of light, fertilizer or salt that you give to a plant to observe how it affects its growth. What you measure is the dependent variable(the variables that change due to the change in independent variable) eg mass of the plant each day or week, number of leaves or height. All other variables are called the control variables(variables that are constant throughout the experiment). These make the experiment a "fair test". In the above experiment if you were to vary the amount of salt in the soil then each plant must be given the same amount of light, fertilizer, water etc.
What is a experimental constant?
There are potential variables that are kept constant for each trial in a set of trials.
What function will be called by default to initialize the member variables of the object of the class?
The constructor. It's run each time a new object is created, usually setup to initialize member variables, but it can do most anything.
How do a control sample and an experimental sample differ from each other?
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
The variables in an experiment that stay the same?
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.

Which part of an investigation is only found in an experimental investigation?
The part of an investigation that is only found in an experimental investigation is the manipulation of an independent variable. In experimental investigations, researchers deliberately change the independent variable to observe the effect on the dependent variable. This manipulation allows for the establishment of cause-and-effect relationships, which is a key component of experimental design. Control over the independent variable is a defining feature of experimental investigations that sets them apart from other types of research designs.

Why is counterbalancing used to control experimental and control groups?
Counterbalancing is used to control for potential confounding variables by ensuring that each participant experiences all levels of the experimental conditions in a different order. This helps to eliminate the influence of any variables that may affect the outcomes of the study, leading to more reliable results and accurate conclusions about the effect of the independent variable.
How to conduct a 2x2 analysis in research methodology?
To conduct a 2x2 analysis in research methodology, you need to categorize your data into two groups each with two variables. Then, you compare the groups to see if there are any significant differences or relationships between the variables. This type of analysis is commonly used in experimental research to examine the effects of two independent variables on a dependent variable.
How is a traditional home setup?
a traditional home is setup with a hut for each room
Where does the variables go the science board?
In a science board display, variables are typically organized in a clear manner to convey their roles in an experiment. Independent variables, which are manipulated, are often listed or highlighted on one side, while dependent variables, which are measured, are placed on the opposite side. Control variables, which remain constant, can be noted in a separate section to illustrate their importance in maintaining experimental integrity. This layout helps viewers easily understand the relationships and significance of each variable in the study.
What is a inderpendent variable?
Dependent variables and independent variables refer to values that change in relationship to each other. The dependent variables are those that are observed to change in response to the independent variables. The independent variables are those that are deliberately manipulated to invoke a change in the dependent variables. In short, "if x is given, then y occurs", where x represents the independent variables and y represents the dependent variables. Depending on the context, independent variables are also known as predictor variables, regressors, controlled variables, manipulated variables, explanatory variables, or input variables. The dependent variable is also known as the response variable, the regressand, the measured variable, the responding variable, the explained variable, the outcome variable, the experimental variable or the output variable.
