ok, the data values are 45, 51, 52, 58, 61, 63, 66, 72, and 74
what is the median?

Answer 7

61?

Answer 8

great! so, to find Q1, we're going to ignore all values that are 61 and above

we're left with 45, 51, 52, 58, what is the median of these 4 values?

Answer 9

51?

Answer 10

nope, not quite
when we have an even number of items, take the middle 2 values, add them, and divide by 2

what is (51+52)/2?

Answer 11

51.5

Answer 12

yup, 51.5 is Q1. we're done ~
