Scores of two teams across sis games team1 { 6, 0, 4, 17, 3, 12} Tram 2. { 23, 14, 22, 14, 17, 22} what is the range of both teams and what team has a more consistent number of goal scored?

1 answer

To find the range of scores for each team, we need to subtract the minimum score from the maximum score.

Team 1 Scores: {6, 0, 4, 17, 3, 12}

  • Maximum Score = 17
  • Minimum Score = 0
  • Range = Maximum - Minimum = 17 - 0 = 17

Team 2 Scores: {23, 14, 22, 14, 17, 22}

  • Maximum Score = 23
  • Minimum Score = 14
  • Range = Maximum - Minimum = 23 - 14 = 9

Now, we can compare the consistency of the two teams. A common method to measure consistency is to calculate the standard deviation of the scores. A lower standard deviation indicates more consistency.

Calculating the Standard Deviation

  1. Team 1:

    • Mean = (6 + 0 + 4 + 17 + 3 + 12) / 6 = 42 / 6 = 7
    • Variance = [(6-7)² + (0-7)² + (4-7)² + (17-7)² + (3-7)² + (12-7)²] / 6
    • Variance = [1 + 49 + 9 + 100 + 16 + 25] / 6 = 200 / 6 ≈ 33.33
    • Standard Deviation = √33.33 ≈ 5.77
  2. Team 2:

    • Mean = (23 + 14 + 22 + 14 + 17 + 22) / 6 = 112 / 6 ≈ 18.67
    • Variance = [(23-18.67)² + (14-18.67)² + (22-18.67)² + (14-18.67)² + (17-18.67)² + (22-18.67)²] / 6
    • Variance = [19.36 + 21.78 + 11.11 + 21.78 + 2.78 + 11.11] / 6
    • Variance = [87.92] / 6 ≈ 14.65
    • Standard Deviation = √14.65 ≈ 3.83

Summary of Results

  • Range of Team 1: 17
  • Range of Team 2: 9
  • Standard Deviation of Team 1: ≈ 5.77
  • Standard Deviation of Team 2: ≈ 3.83

Conclusion

  • Team 2 has a smaller range (9) compared to Team 1 (17), indicating that Team 2 has a more consistent score across the games.
  • Additionally, Team 2's standard deviation (≈ 3.83) is lower than that of Team 1 (≈ 5.77), confirming that Team 2 is more consistent in scoring.
