mean,range,median,mode: in class of 28 6th-graders, all but

can anyone help me solve this problem

in a class of 28 sixth graders all but one of the students are 12 years old. which two data measurements are the same for students ages? what are those measurements

Try picking a different value for the twenty-eighth student, and computing the various values. What is the mean? What is the mode? What is the median? What is the range? Which two values matched?

If you're not sure of your solution, pick another different value for the twenty-eighth student, and do the computations again.

If you get stuck, please reply showing how far you have gotten. Thank you.
