Answer:
since the median means middle, you lay the numbers out from least to greatest.
Step-by-step explanation:
52, 72, 96, 21, 58, 40, 75 would go to
21, 40, 52, 58, 72, 75, 96.
then you cross out the numbers in a pattern so like
no more 21 and no more 96
no more 40, and no more 75
no more 52 and no more 72
this leaves you with 58!
