Look below :)

You first determine the value of $Q_1$ and $Q_3$ .

Once you have found these values you subtract:

$Q_3-Q_1$

This is called the interquartile range.

Now you multiply your result by $1.5$

$(Q_3-Q_1) xx 1.5= R$

$R="your result"$

Then you add your result $(R)$ to $Q_3$

$R+Q_3$

And subtract $Q_1 - R$

You will have two numbers this will be a range. Any number located outside this range is consider an outlier.
