I'm having a bit of trouble wrapping my head around the material in this course thus far. I know why I'm having trouble, I need to be shown how to look at and complete a math problem and then walked through a few examples as I do them myself. I've always needed a mesh of hands on and direct instruction to understand new math concepts. I'm hoping we walk through how to do these problems in Monday's course or I'm going to be completely lost!! I did figure out how to compute mean, mode, median, etc using excel, which has been very helpful, but I still am lost as to how to use this data to figure out problems. I did my best to complete the worksheets for Monday, but I'm not sure I did them completely right.
Here are my questions:
What exactly does Standard Deviation tell use about a sample?
When graphing a sample, do you graph in the order you have the data listed, or do you sort the data in order?
How do you graph skew?
If mode and range are not very useful, why do we calculate them?
How do I use mean, median, mode, SD, range, and skew to get a "whole" picture of what a population might look like?
I also struggled with the assignemnts this week. I know how to do mean, median,mode, but beyond that I am struggling. How did you get the data from the CDC site? Every catagory I try to download says no dataline???
