Question

people on a whale - watching trip compared the number of whales they saw. whale watching whales spotted what is the mean of the numbers?

Explanation:

Step1: Count the number of X's for each value

• For 0 whales: 2 X's, so total is \(0\times2 = 0\)
• For 1 whale: 3 X's, so total is \(1\times3 = 3\)
• For 2 whales: 1 X, so total is \(2\times1 = 2\)
• For 3 whales: 2 X's, so total is \(3\times2 = 6\)
• For 4 whales: 1 X, so total is \(4\times1 = 4\)
• For 5 whales: 1 X, so total is \(5\times1 = 5\)
• For 6 whales: 0 X's, so total is \(6\times0 = 0\)

Step2: Calculate the sum of all values

Sum = \(0 + 3 + 2 + 6 + 4 + 5 + 0 = 20\)

Step3: Calculate the total number of people (total number of X's)

Total number of X's = \(2 + 3 + 1 + 2 + 1 + 1 + 0 = 10\)

Step4: Calculate the mean

Mean = \(\frac{\text{Sum}}{\text{Total number of people}} = \frac{20}{10} = 2\)
