Answer:
C). Provide a summation of survey results, without the grades.
Explanation:
As per the given description, the statement that is true is displayed through option C. It says that it 'provides a summation of survey results, without the grades' as it is substantiated with the description 'the study requires the analysis of identifiable student performance data'. This data analysis would assist the researcher to present the totality of the results acquired from the survey.
The other options could not be considered true as they assert a false claim. Option A is false as 'it doesn't involve names' neither does it 'include grades' as the focus is to 'look for children requiring special needs in local schools'(not the grades). Option D is incorrect as it offers an aggregate of the survey results and does not involve the 'ranges'. Thus, option C is the correct answer.
