To find iqr you find 3/4 of the data known as the upper quartile
And the 25th percentile 1/4 of the data , known as the lower quartile
Then do upper quartile - lower quartile to get the iqr

#

If you do frequency divided by 4 and then use the curve to match it to the corresponding X value you will get the lower quartilr

#

Then frequency * 3/4 and do the same thing to find the upper quartilr
