The table above shows the scores of 20 students in further mathematics test. What is the range of the distribution?

Answer Details

The range of a distribution is the difference between the highest and lowest values in the distribution. In this case, the highest score is 10 and the lowest score is 3. Therefore, the range of the distribution is: 10 - 3 = 7 So the correct option is 7.
