Question

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.

Answer 1

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

Answer 2

@EclipsedStar
@Jane

Answer 3

@nincompoop

Answer 4

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. :)

Answer 5

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

Answer 6

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 :)

Answer 7

Alright

Answer 8

hmmm I prefer fractions over this.

Answer 9

And I hate fractions. Sorry.

Answer 10

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!

Answer 11

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

Answer 12

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

Answer 13

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.

Answer 14

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

Answer 15

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

Answer 16

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.

Answer 17

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.

Answer 18

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.

Answer 19

Do you KNOW what a five-number summary is?

Answer 20

Some what

Answer 21

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.

Answer 22

Alright

Answer 23

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.

Answer 24

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

Answer 25

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

Answer 26

10 11 12 13 14 14 15 15 16

Answer 27

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

Answer 28

Interquartile range is Q3-Q1

Answer 29

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

Answer 30

ok

Answer 31

brb

Answer 32

Sorry I was eating lunch now I am back

Answer 33

Q1 is 4 and 10

Answer 34

Q3 is 7 and 14
