My son has this homework and I am all confused... the paper says to think back to the experiment you just designed to test the Best Wheels Bike Shop's new super titanium wheel bearings. He did not do this experiment which leads me to believe this is just a statement for the kids to answer these questions.
1- what was the independent variable in your experiment? And was there more than one?
2- what was the dependent variable in your experiment?
I have no clue what to answer, I think the independent variable is the wheel bearings but not sure if that is right and the dependent variable could be weather?
You haven't posted enough information about the experiment. The questions cannot be answered without that information.
How many groups of 14 can you make with 9
its a question on my math homework and i need to make it into a mixed number????
please help me?
Alicia the fraction and mixed number i 1 and 5/14
And you need to do the expirement to answer these questions
I understand your confusion, but don't worry, I can help you figure out the answers to these questions. To determine the independent and dependent variables in an experiment, you need to consider the cause and effect relationship being investigated.
1. The independent variable (IV) is the factor that is deliberately manipulated or changed by the researcher. It is the variable that you, or in this case, your son, have control over. In the context of testing the super titanium wheel bearings, the independent variable could be something like the type of wheel bearings used. For example, your son could have used two different types of wheel bearings, such as the new super titanium wheel bearings and the old standard wheel bearings. If that's the case, the independent variable would be the type of wheel bearings used. There should generally be only one independent variable in an experiment, unless you are testing multiple levels or variations of a single factor.
2. The dependent variable (DV) is the factor that is being measured or observed and is expected to change as a result of manipulating the independent variable(s). In this case, the dependent variable would be an aspect related to the performance of the bike or the wheel bearings. For example, your son could have measured the speed of the bike or the distance it traveled using the different wheel bearings. The dependent variable should be something that can be quantitatively or qualitatively measured.
It's important to note that the weather itself is not likely to be either the independent or dependent variable in this experiment. However, weather conditions could be a controlled variable if your son took precautions to conduct the experiment under consistent weather conditions.
To fully answer these questions, your son would need to describe the specific details of the experiment he designed. But I hope this explanation helps you understand the concepts of independent and dependent variables a bit better, so you can work with your son to come up with an appropriate response.
