the way you have laid this question out is strange but im assuming you want me to find the mean, range, medium and mode of the numbers provided?
Answer:
median=order them and find the middle= 6
mean=add them all up and divide by the amount of numbers=(6+13+7+9+5+3+2+5+4+10+12)/11=6.9
range= the difference between the smallest and largest number=13-2=11
mode= the one that appears the most= 5
