Why is a control group needed?
A control group is subjected to the same procedures as the experimental group but does not receive the treatment of the independent variable. In the control group all variables are held constant. It is used as a baseline measure. This helps determine whether any of the resulting effects of the experimental group are due to the independent variable treatment and not to the actions involved in providing the treatment.
In a controlled experiment what does a operational definition do?
An operational definition provides a clear and specific description of how a variable will be measured or manipulated in a study. It helps ensure that the variable is defined in a way that can be consistently applied and observed, making the results more reliable and replicable.
Why are controls not needed in the Arthropoda experiment described in the study guide?
Controls are not needed in the Arthropoda experiment if the focus is simply on observing the behavior or characteristics of Arthropoda in a specific environment. In this case, the purpose is not to compare a treatment group against a control group, but to solely observe and record information about Arthropoda. However, if the experiment involves testing a specific hypothesis or comparing different treatments on Arthropoda, then controls would be necessary.
Why are controls not needed in the arthropods experiment described i the study guide?
Controls are not needed in the arthropods experiment because the study does not involve comparing treatments or conditions. The purpose of the experiment is simply to observe and describe arthropods in a specific environment, rather than testing a hypothesis or comparing experimental groups. Controls are typically used when comparing treatments to ensure any observed effects are due to the treatment itself and not other factors.
Why are controls no needed in the arthropods experiment described in the study guide?
Controls are not needed in the arthropods experiment described in the study guide because the purpose is to observe the natural behavior or characteristic of the arthropods in their environment without any manipulation or comparison with a control group. This type of observational study does not require controls to assess the behavior or traits being studied.
How many manipulated variable are in an experiment?
as many as needed
When an experiment shows that two variable are closely related what does the experiment show?
The experiment shows that there is a correlation between the two variables, meaning that as one variable changes, the other variable changes in a consistent way. However, it does not necessarily establish a cause-and-effect relationship between the variables. Further analysis is needed to determine causation.
When an experiment showes that two variable are closely related the experiment shows?
correlation
Why a control needed in a valid experiment?
A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.
What are the most important controls needed in this experiment?
It is a conclusion,variable,a hypothesis,procedure,and data.
What is the experiment to find out how much acid is needed to dissolve a certain amount of alkali?
To determine how much acid is needed to dissolve a specific amount of alkali, you can conduct a titration experiment. Add a known volume of acid of known concentration to the alkali solution until the alkali is completely neutralized. By recording the volume of acid used, you can calculate the amount needed to dissolve the alkali based on the stoichiometry of the reaction.
Are controls always necessary in an experiment?
Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results
What amount of oxygen is needed for a complete combustion reaction in manipulated variable?
9
The amount of time needed to run the Boston Marathon is an example of which type of variable?
A continuous variable which is made discrete when recorded.
When an experiment shows that two variable ate closely related the experiment shows?
that there is a strong correlation between the two variables. This suggests that a change in one variable is associated with a change in the other variable. However, correlation does not imply causation, so further experiments are needed to establish if there is a causal relationship between the variables.
Why is an idependent variable needed?
An independent variable is a variable that you can control, you can choose and manipulate this variable. An example is an experiment looking at the growth of trees in the Dark, in a dimly lit room and in the direct sun. So you are going to put one plant in the sun, one in the dark and another in a dimly lit room. The independent variable is the location of the experiment, because this is what is being changed. The dependent variable may be the type of the plants and the height of the plants to begin with, The results on which is determined by the independent variable (ie amount of sunlight on the plants) So basically, without the independent variable you cannot really measure the full extent of the results. Uhm, I hope that makes sense, haha.
Which conclusion could the student draw this experiment?
Based on the results of the experiment, the student could conclude that the independent variable had a significant effect on the dependent variable. Additionally, the student could suggest that further research is needed to explore the relationship between the variables in more depth.
