Stat problems for Friday, Jan 22

1. I've got a data file with some statistics for all 1199 Major League Baseball players in 2010. The first few lines look something like so:

   Name	Team	Number	Pos	Games	At bats	Hits	Home Runs	On base %	Bat Avg
   I Suzuki	SEA	51	OF	162	680	214	6	0.359	0.315
   D Jeter	NYY	2	SS	157	663	179	10	0.340	0.270
   M Young	TEX	10	3B	157	656	186	21	0.330	0.284
   J Pierre	CWS	1	OF	160	651	179	1	0.341	0.275
   R Weeks	MIL	23	2B	160	651	175	29	0.366	0.269

   1. What does each row represent?
   2. Identify the variables in this data table and classify each as
      1. Continuous numeric,
      2. Discrete numeric,
      3. Nominal categoric, or
      4. ordinal categoric
2. Baseball teams are formed by players who play a number of different positions while they are playing defense on the field:
   • P: Pitcher
   • C: Catcher
   • 1B: First base
   • 2B: Second base
   • 3B: Third base
   • SS: Short stop
   • OF: Outfield
   • DH: Designated hitter
   Statistically speaking, some defensive positions tend to be better batters than other. To illustrate, the image below uses our 2010 data set to form a collection of side-by-side box plots for the relationship between a player's position on the horizontal axis and their On Base Percentage (OBP) on the vertical axis. Use this image to roughly rank positions.
   • Use this image to roughly rank the median OBP by a player's position.
   • How would compare the OBP of third baseman (3B) to designated hitters (DH)?
