It seems that the given data consists of two sets of numbers separated by an equals sign. The first set of numbers appears to be a list of math test scores, while the second set of numbers is unclear.
Assuming that the question is asking about the number of students represented by the first set of numbers (the math test scores), then the answer would be 31. This is because there are 31 numbers in the list, which could represent the scores of 31 individual students.
