For a class of 30 students, the scores in a Mathematics test out of 10 marks were as follows; 4,5,7,2,3,6,5,5,8,9,5,4,2,3,7,9,8,7,7,7,3,4,5,5,2,3,6,7,7,2 Wh...
Range of a distribution refers to the difference between the highest and lowest value in a dataset.
To find the range of the given Mathematics test scores, we need to determine the highest and lowest values.
The lowest score in the test is 2, while the highest score is 9.
Therefore, the range of the distribution is 9 - 2 = 7.
Hence, the answer is 7.
