Question

the dot plot below represents the number of goals scored by the boys soccer team in every game so far this season.
goals scored
0: two dots, 1: two dots, 2: zero dots, 3: three dots, 4: one dot, 5: two dots
what was the mean number of goals scored?
answer attempt 1 out of 10
goals

Explanation:

Step1: Count dots per goal

• 0 goals: 2 dots (total \(0\times2 = 0\))
• 1 goal: 2 dots (total \(1\times2 = 2\))
• 3 goals: 3 dots (total \(3\times3 = 9\))
• 4 goals: 1 dot (total \(4\times1 = 4\))
• 5 goals: 2 dots (total \(5\times2 = 10\))

Step2: Sum total goals

Total goals = \(0 + 2 + 9 + 4 + 10 = 25\)

Step3: Count total games

Total games = \(2 + 2 + 3 + 1 + 2 = 10\)

Step4: Calculate mean

Mean = \(\frac{25}{10} = 2.5\)

Answer:

2.5
