Speaker: Okay. Hello students.
Now we are going to 1C,
where we are gonna learn how to compete the median.
So calculating the median is actually quite simple.
What the median is, is our physical midpoint
but it is the physical midpoint of the ordered data set.
So we have, first and foremost, learned how to do that.
So we are going to write down again,
the ordered data set here.
So now, what I'm going to do is go here
and select a different color for my pen tip, like a pink.
And I am going to now kind of put the numbers here.
So basically, this is the first, second, third,
fourth, fifth, sixth, seventh, eighth and ninth.
So this is basically our order data set,
smallest to largest.
So now, we are looking for the physical midpoint.
So as we all know, when our set of numbers is nine,
then the physical midpoint is going to be five.
So this is going to be our median.
So again, key here is
an ordered set.
So in an ordered set, your median is your physical midpoint.
Very simple.
Okay, so now we are going to go to the next one
and that will be 1D.
