Q. Looking at the data for first base (1B) players, which of the following statements is accurate for the sample?

• A. They steal bases quite often.
• B. Of the three variables the players batting average is the most consistent.
• C. Using this graph, if you know how many homes runs a player hit, then you can estimate the steals for that player.

[ Select ] ["A", "B", "C"]

Q. Looking at the data for second base (2B) players, which of the following statements is accurate for the sample?

• A. Their batting average is often above 0.25.
• B. They tend to steal bases often.
• C. The higher the number of a players home runs, the higher the batting average.

[ Select ] ["A", "B", "C"]

Q. Looking at the data for both types of players at once, indicate whether the statement is TRUE or FALSE according to the sample.

• A. The first base players tend to hit more home runs than second base players. [ Select ] ["TRUE", "FALSE"]
• B. Each second base player has stolen more bases than any first base player. [ Select ] ["TRUE", "FALSE"]
• C. Every first base player has hit more home runs than every second base player. [ Select ] ["TRUE", "FALSE"]
• D. The second base players always have lower batting averages than first base players. [ Select ] ["TRUE", "FALSE"]

A parallel coordinates plot, stretches or condenses the vertical axes so they look to be the same height for each variable. This ables the reader to see patterns in the relationship between variables across subjects. The graph below plots seasonal data for baseball players playing two different positions: first base (1B), the solid blue line second base (2B) the dashed red line. Players are compared across the three dimensions: home runs (number of home runs hit) steals (bases stolen) batting average Home Runs Steals Average 0.34 40 2B 35 -0.32 30 0.30 25 20 -0.28 15 -0.26 10 -5 -0.24 1B 0 -0 0.22 Created by Gary McClelland, Professor Emeritus University of Colorado Boulder
