In Science experiments, it is very important to consider controlled variables so that there is only ONE independent variable and ONE dependent variable. We “control the variables” by making anything else that could change during the experiment into a constant. For example, if you are doing an experiment to find out what material can hold more water, then it is important to make sure all the materials you are testing are the same size, the experiment is happening at the same temperature, with the same amount of water, etc. In 2-3 complete sentences, explain why controlled variables are so important to an experiment.

Answer #1

it is very important to consider controlled variables you could only change one manipulated/independent variable to confirm what caused changes in responding/dependent variable.

The main aim of a controlled variable is to maintain all conditions as similar as possible between 2 subjects except for the independent variable. Controlled variables makes it easier to reproduce an experiment and setup relation between dependent and independent variables.

1.Quit Smoking: The New England Journal of Medicine published the results of a double-blind, placebo-controlled experiment to study the effect of nicotine patches and the antidepressant bupropion on quitting smoking. The target for quitting smoking was the 8th day of the experiment. In this experiment researchers randomly assigned smokers to treatments. We conducted a hypothesis test to determine if the side effect rates are significantly different for nicotine patches versus bupropion at a 5% level of significance. (The normality conditions...

For the following experiments/questions, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all.  Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...

Activity 1: Scientific Reports You may have heard the question “If a tree falls in a forest and no one is around to hear it, does it make a sound?” A similar question can be asked about experiments. “If a researcher performs an experiment and never publishes the result has science been performed?” Many people would say no because science is the accumulation of knowledge. If the results of an experiment are not published, knowledge is not gained. The final...

What do you predict will happen (do you expect something different than the hypothesis in the researcher instructions? If so, what and why?)? Do you think...
