Statistics rap

The interquartile range is one of the kings

This is used to find the average range for several things;

Such as the size of shoes, clothes and rings.

 

To find the middle number, the median

Chance the numbers from the smallest to the biggest

You don't need to be the quickest

 

Now when you have four quarters and three median

Pat yourself on the back and get a snack

 

The median can now be called Q2

Keep working don't say adiue

 

We should call the other medians Q1 and Q3

Now you can get yourself a cup of tea

 

To get our interquartile range we need to subtract

Don't lose your tact we will get through this it is a pact

 

Q3 minus Q1 will give you the answer you wanted

The size of clothes will be good so don't be daunted.

 

We now have our IQR

To make it easier we will make it into a graph

 

It is called a box and whisker plot

This will make our data for our clothes look nice Jackpot!

 

You have now found the average rage for clothes

So now you to know what your customers will choose.

 

So now lets make some examples

I went to find clothes and i got some size samples

 

2,4,8,12,16 was the sizes that I found

So the median would be 8 all year around

 

Q1 would be 3 since it is in the middle of 2 and 4

Q3 would be 14 now that we have our numbers don't walk out of the door

 

Now subtract 14 - 3 to get the number 11

Now we have the IQR this is heaven.

 

In the box and whisker plot you include the Q1, Q2 and Q3

The normal rage would be between Q1 and Q3

 

We will also include the highest and lowest number

Q1 is 3 Q2 is 8 and Q3 14 and the highest number is 16 and the lowest 2

 

There now we are done and now we know how to find the interquartile range

good job well now that wasn't so strange.
