Variables that are kept the same for each experimental set-up are called "controlled variables" or "constants." These are crucial to ensure that any observed changes in the experiment can be attributed to the independent variable, rather than other factors. By maintaining these constants, researchers can improve the reliability and validity of their results.

What is the experiment called in which all the features of each experimental group are exactly the same except for the independent variable?

The experiment is called a controlled experiment. In this type of experiment, all variables are kept constant across experimental groups, except for the independent variable, which is deliberately manipulated to observe its effect on the dependent variable. This design helps to ensure that any observed changes can be attributed solely to the manipulation of the independent variable.


If you set up an experiment with two different independent variables then the results would be?

If you set up an experiment with two different independent variables, the results would allow you to analyze the effects of each variable independently and potentially their interaction effect on the dependent variable. This design can provide insights into how each variable influences the outcome and whether they affect each other. However, it's important to ensure that the experimental setup controls for confounding factors to accurately interpret the results. Proper statistical analysis will be necessary to draw valid conclusions from the data collected.


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 are some characteristics of an experimental procedure?

An experimental procedure is characterized by a systematic approach to testing hypotheses through controlled conditions. Key features include the formulation of a clear hypothesis, the use of control and experimental groups, and the standardization of variables to ensure reliable results. Additionally, it often involves repeated trials to verify findings and minimize errors. Documentation of each step is crucial for reproducibility and validation of the results.

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.


Why do think the experimental result were different for each trial?

Experimental results can vary between trials due to several factors, including variations in environmental conditions, measurement errors, or inconsistencies in the experimental setup. Additionally, natural variability in the materials or biological subjects used can lead to differing outcomes. Human error in conducting the experiment or recording data can also contribute to discrepancies. Consistently monitoring and controlling these variables can help reduce variations and improve the reliability of results.

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.
