Variables are the basis of a scientific experiment. When the scientist is carrying out his procedure, he is actually altering a variable, called the independent variable. Unless he just likes playing with chemicals, he is likely attempting to get a result, and he does this by using measurements of the dependent variable, which has changed because of the manipulation of the independent variable. Identifying the variables becomes very important when formulating more complicated studies, and becomes the bread and butter of psychological experiments.

Andrea is testing balloon rockets by using balloons with different amount of air Identify the three variables Andrea will need to control?
smoothness,weight and strenght
What special skills would you need to be a successful forensic scientist?
A Phd in physics or chemistry would be useful.not entirally needed
What do Sometimes scientist make a mistake or what and need to do the experiment again?
Scientists may make mistakes due to errors in experimental design, measurement inaccuracies, or uncontrolled variables. These mistakes can lead to incorrect conclusions, prompting the need for repetition of the experiment to ensure reliability and accuracy. Additionally, peer review and replication by other researchers can help identify these errors and confirm findings. Ultimately, acknowledging and correcting mistakes is a crucial part of the scientific process.
What can scientist infer from the similarties between these two structures?
We would need to know what the two structures are to respond to this question.
Why does a scientist need to be creative?
imagination
Why would a scientists need to identify and control variables in an experiment?
A scientist would need to identify variables so you could know what to change and what to keep the same. A scientist would need to control variables so you can try to see exactly which factors are affecting the dependent variable (the thing you're measuring). Hope this helped! Because I have the exact same question on my homework!
How do you identify the register variables?
Registry variables can be identified with registry allocation. The programmer will decide on the variables that need to be assigned to the registry, and variables not assigned to the registry will be held in RAM.
Why would a scientist using radiation need to have a background in cellular biology?
The scientist would not.
Why would a scientist need to do an experiment again?
donut
When would a scientist use a dichotomous key?
When the scientist isn't sure what an organism or animal is, he or she would then go through all of the questions until they reach the end where the name of the cell or animal would be, or maybe they could find that it is a new discovery.
Why do you need scientists?
you need scientist because without them how would we have rockets or any technology
What scientist would you need to build a device that can help you breathe 10m underwater?
You wouldn't need a scientist of any particular specialty to build a device.
Andrea is testing balloon rockets by using balloons with different amount of air Identify the three variables Andrea will need to control?
smoothness,weight and strenght
Identify the variables that you need to control and the variable that you will change?
To conduct a controlled experiment, you need to control all variables except the one you are changing. The variable you change is called the independent variable, and the variable you measure in response is the dependent variable. Control variables are those that could potentially affect the outcome of the experiment but are kept constant to isolate the effect of the independent variable.
Identify which of the following would be composed of cells?
I need help
Is object a member of a class?
Yes, you would need to define your variables. Also initialize them
