no, just take away the number bigger than the median. so now you only look at 45, 51,52,and 58 and find the median

52

oh ok i was counting 61 thats why

you don't include 61 in this set. So you end up with 51 and 52 for the median, so you go in the middle,

9 data points,  divided by 4 is:  1Q = 2.something  so we round up to 3 and pick the 3rd value

if we had ended up with say 1Q = 2,  then we would have had to average the 2nd and 3rd values.
