The table below shows the number of hours some college athletes in two states spend on indoor sports each week:
State A 7 9 5 4 25 21 6 6 8
State B 14 12 10 13 15 14 11 15 16
Part A: Create a five-number summary and calculate the interquartile range for the two sets of data.

Sometimes I wonder why they make us do things only 5% of us will use in their lives....

They make you do this because someone able to do this is more impressive than someone who can't and employers want someone who can do more. :)

Sure ok still doesn't take away the fact it is annoying and that I hate algebra... anyway can you help me out?

- anonymous

Sure, I'm gonna google these terms as I have forgotten some of em' but I'll be back in a couple minutes to help :)

- anonymous

Alright

- anonymous

hmmm I prefer fractions over this.

- anonymous

And I hate fractions. Sorry.

- anonymous

Yeah no I prefere getting beat on the side of the head than doing this but hey life HAHAHAHAHA people and jobs enjoy making it more complex than it really is!

- anonymous

Well if you're the employer you choose the person more qualified to do the job...

- anonymous

Yes but what if the job has nothing to do with Algebra my point only a tiny percent of jobs need you to learn this

- anonymous

I mean if you want to do manual labor then you don't need to bother with school, just drop out and get ready for a life of hard work.

- anonymous

No man I am staying in school I simply dislike this class

- anonymous

And knowing how to make graphs, and manipulate data is used in lots of jobs, accounting included.

- anonymous

If you don't know how to do this, you won't get to higher maths. No higher maths cuts off lots of mathematician jobs and scientific jobs. In other words, high-paying jobs. If you want to work an easy jobs, all you really need are decent grades. But the better a job you want, the more effort you need to put in school to do good.

- anonymous

I said I hate this class, but if it will pay me later in life do I have a choice? 95% of the people in the world HATE there jobs but they do them! Why? Because they need money and be able to sustain a decent life! I don't want to be a Scientist, in fact I always wanted to be a director or a lawyer, I still need some basic math but Algebra just makes things more COMPLEX there are better ways on figuering out problems than making an Equation.

- anonymous

Equations are the best way to represent an idea to a large group of people :). I use equations much more than manually trying to explain things on here. They also give something to fall back on. But whatever, let's get on to formatting this problem.

Do you KNOW what a five-number summary is?

- anonymous

Some what

- anonymous

http://www.mathwords.com/f/five_number_summary.htm http://www.purplemath.com/modules/boxwhisk.htm It's pretty much just the literal representation of a box-and-whisker plot. So we're going to be figuring out the 5 quartiles of each set of data.

- anonymous

Alright

- anonymous

Q1, Q3, and Q5 are all easy. Q1 and Q5 are the minimum and maximum, respectively. They are usually just referred to as the minimum and maximum, while Q2 and Q4 are referred to as Q1 and Q3. So for data set A, the minimum is 4 and the maximum is 25. Q3 (usually referred to as Q2) will be the median of the set.

- anonymous

I'd recommend re-writing the data set from least to greatest first though :)

- anonymous

Makes it more simple ok here goes nothing
4 5 6 6 7 8 9 21 25

- anonymous

10 11 12 13 14 14 15 15 16

- anonymous

Minimum is the smallest number
Q1 is the average of the numbers between the minimum and the median
Median is the middle number
Q3 is the average of the numbers between the median and the maximum
Maximum is the biggest number

- anonymous

Interquartile range is Q3-Q1

- anonymous

That's all you really need to know. All that's left is doing the calculations.

- anonymous

ok

- anonymous

brb

- anonymous

Sorry I was eating lunch now I am back

- anonymous

Q1 is 4 and 10

- anonymous

Q3 is 7 and 14
