If a dataset shows the values 4, 7, 7, 8, 10, what is the mean?

• A. 7.2
• B. 8
• C. 8.5
• D. 9

Answer: (A)

To find the mean of a dataset, you sum all the values and then divide by the number of values. In this case, the values are 4, 7, 7, 8, and 10. First, add these values together: 4 + 7 + 7 + 8 + 10 = 36. Next, count how many values there are in the dataset, which is 5 in this instance. Now, divide the total sum by the number of values: 36 ÷ 5 = 7.2. This calculation shows that the mean of the dataset is 7.2, making the first option the correct answer. Each step demonstrates how to compute the mean, ensuring a clear understanding of the process involved.
