Use statistics to explain the data collected by your science projects and experiments...
Science fair projects on probability and statistical analysis can be a great way to learn how to apply statistics to your science projects and experiments. Statistics will help you to both describe the test subjects you will be working with as well as to help you to analyze your results. If you are new to science fair projects then the following information will be very helpful.
Standard deviation is another important concept that you will need familiarize yourself with when developing science fair projects on probability and statistical analysis. Standard deviation is calculated by first figuring out what the mean of the data point values is. You will then calculate how far away each data point is from the mean. Then add these values together and divide it by the number of data points in the set. This is your standard deviation. This value will be used for calculating much more complex statistical values later on in your science career. Statistics can be used for many purposes. First of all you can use statistics to examine the population that you will be working with in your experiment. For example you can calculate the mean test score for a class room and then use this information to categorize students into test groups based on their scores. Statistics can also be used for predicting the outcome of your experiment. This option will help you to come up with a hypothesis for your experiments. For example, if statistics show that 25 percent of a given population will have blue eyes, then you can propose a hypothesis that states that 25 percent of your test sample will have blue eyes. You will then select your sample population and test them to see if your prediction is correct or incorrect. You will again use statistics to describe your results and to explain your results. The difference between a good science fair project and a really bad science fair project usually depends on how the student utilized statistics and probability in their project. Good projects will properly use statistics and probability throughout their experiment and bad projects will either fail to use these tools all together or they will use them inappropriately. Now that you know what makes a good project you are in the perfect position to develop a winning project. Copyright © 2003 - 2010 Super Science Fair Projects - All Rights Reserved.
