Chapter 4

 

1. Where did I struggle? I sometimes struggle on identify the different between the mean and standard deviation when comes to a graphical display.

2. What questions do I still have? 

3. What am I going to do to strengthen my understanding? I should read the book more and look for a lot of examples and exercises. 

 

Two key things you learned from this unit. (What are your understandings? What are you taking away from this? What real world applications have you seen? What links to other subjects did you see?)

 

-I learned that the mean is affected from the outliers, while the median does not.

-The z-score is how many value it is away from the mean.
