Question

You have assessed twenty peers of your class for mathematical comprehension/knowledge. Create a distribution for the results that you are most likely to expect. What is the shape of the distribution?

Answer 1

1. The score distribution forms an approximate bell-shaped curve known as the normal probability curve.
2. In this case, 10 individuals would score around the average, while the remaining 10 would score either above or below it.
3. This distribution is symmetrical around the central value, known as the mean.
4. The left side of the curve is a mirror image of the right side.
5. People differ in their level of mathematical ability.
6. As a result, most scores cluster around the middle of the distribution.
7. Only a small number of individuals obtain very high or very low scores.
