Assingment 7- SOCR Website

After playing around with the website I found the "Distributions" tab interesting. What I liked about this function is that you can see how a distribution graph will look like if the mean or standard deviation change and you can also see how a variety of different distributions look like by choosing them from the list under SOCR Distributions.
This feature will be useful in the classroom because it gives us an example of what the different distributions look like under different conditions, like an increase in the mean or standard deviation.
