The following scores were given by 8 students. 12,15,18,10,20,15,10,14 Calculate the mean The total score The number of students who scored above the mean

The total score is the sum of all individual scores.

$$\text{Total Score} = 12 + 15 + 18 + 10 + 20 + 15 + 10 + 14$$ $$\text{Total Score} = 114$$

The total score is $\boxed{114}$.

The mean is the total score divided by the number of students. There are 8 students.

$$\text{Mean} = \frac{\text{Total Score}}{\text{Number of Students}}$$ $$\text{Mean} = \frac{114}{8}$$ $$\text{Mean} = 14.25$$

The mean score is $\boxed{14.25}$.

We compare each score to the mean (14.25):

• $12 < 14.25$
• $15 > 14.25$
• $18 > 14.25$
• $10 < 14.25$
• $20 > 14.25$
• $15 > 14.25$
• $10 < 14.25$
• $14 < 14.25$ The scores above the mean are $15, 18, 20, 15$. There are 4 students who scored above the mean. The number of students who scored above the mean is $\boxed{4}$.
