Finding Interquartile Range Using Normal Distribution

[@keenanmacarthur9367]

Thank you. Your explanation made this concept really easy to understand.

[@SophieBrown-o2l]

Thanks so much! Every other tutorial seems to use the graphic calculator which I do not have

[@Rebecca-ck3qq]

Thanks for the help, it helped me

Where did you find that nifty z-score table that shows the differences? I could only find tables without the differences on google.
Thank you for the upload!

I have a math problem that has the values of the IQR and mean and wants me to find the standard deviation. I am so confused

[@JennaMyJenna1]

ALSO to help people, faster is to
IQR= 1.34896 x standard deviation

Bless you :,)

[@bigmansanister8716]

I dont understand how you find Z

[@mukulpoudel5665]

We just want the value of x that will give probability 0.75(0.25)
So we find value from the z table by looking at the probability and interpolate it to get the exact number.
