Over the past 6 ​seasons, one baseball​ player's batting averages were 0.202​, 0.364​, 0.333​, 0.276​, 0.281​, and 0.277. A second​ player's batting averages were 0.324​, 0.338​, 0.296​, 0.238​, 0.327​, and 0.196. What are the range and mean of each​ player's batting​ averages? Use your results to compare the​ players' batting skills.

To find the range and mean of each player's batting averages, we'll first organize and calculate for each player.

Player 1 Batting Averages:

  • Averages: 0.202, 0.364, 0.333, 0.276, 0.281, 0.277

Calculating Range:

  1. Maximum: The highest value is 0.364.
  2. Minimum: The lowest value is 0.202.
  3. Range = Maximum - Minimum = 0.364 - 0.202 = 0.162

Calculating Mean: \[ \text{Mean} = \frac{\text{Sum of averages}}{\text{Number of seasons}} = \frac{0.202 + 0.364 + 0.333 + 0.276 + 0.281 + 0.277}{6} \] \[ = \frac{1.733}{6} \approx 0.2888 \]

Player 2 Batting Averages:

  • Averages: 0.324, 0.338, 0.296, 0.238, 0.327, 0.196

Calculating Range:

  1. Maximum: The highest value is 0.338.
  2. Minimum: The lowest value is 0.196.
  3. Range = Maximum - Minimum = 0.338 - 0.196 = 0.142

Calculating Mean: \[ \text{Mean} = \frac{\text{Sum of averages}}{\text{Number of seasons}} = \frac{0.324 + 0.338 + 0.296 + 0.238 + 0.327 + 0.196}{6} \] \[ = \frac{1.719}{6} \approx 0.2865 \]

Summary of Results:

  • Player 1:

    • Range: 0.162
    • Mean: 0.2888
  • Player 2:

    • Range: 0.142
    • Mean: 0.2865

Comparison:

  • The mean of Player 1 (0.2888) is slightly higher than the mean of Player 2 (0.2865), indicating that Player 1 has a marginally better overall batting average across the six seasons.
  • The range for Player 1 (0.162) is greater than that of Player 2 (0.142), which suggests that Player 1 had more variability in their performance levels than Player 2. Player 1 had a performance peak at 0.364 while Player 2's peak was lower (0.338).

In summary, while Player 1 has a slightly better mean and more variability in their performance, both players have their strengths and weaknesses reflected in their batting averages.
