Instructions
1) First, you will create a discussion board post where you solve a homework question *and* provide an explanation for how you solved the question.  Sometimes, the explanation may be as simple as you used StarCrunch.  If so, provide the specific function that you used in StatCrunch.  More often, you will find that you need to analyze the information that is given in the problem and use definitions or techniques described in the instructional videos.  When this occurs, you will describe how you analyzed the problem and what definition/technique you used.  This will become natural with practice.  This counts as your first post of the week.  
2) For your second post, you will reply to one of your colleagues in the class.  In that reply, you will highlight the information in their explanation that you found particularly helpful in understanding how they solved the problem.  This could include the language that they used in their explanation that made the explanation particularly clear or it could include how they referenced the definitions that they used or the analysis that they performed to solve the question.  The goal is to develop your ability to explain how you solve statistics questions by reading the explanations of your colleagues and learning from them.
Week 1:
Researchers conducted a study on brain size as measured by pixels in a magnetic resonance imagery (MRI) scan.  The numbers are in hundreds of thousands of pixels.  The data table provides the sizes of the brains and the gender.  Complete parts a through c. 
Brain /Male
b) Explain the coding.  What do 1 and 0 represent?  Why?
c) If you answered “stacked” in part a, then unstach the data into two columns labeled Male and Female.  If you answered “unstacked”, then stack the data into one column with an appropriate name for the stacked variable.  Explain how you either stacked or unstacked the data.
