AnimeGhoul8863:

can u help blackghost

563blackghost:

Sorry I was looking at something real quick, yes i can help!

563blackghost:

though I don't know what a five-number summary is, but i do know how to find the interquartile range......

AnimeGhoul8863:

YEAH!!!!!

563blackghost:

First you need to identify the median. First list the sets in order from least to greatest then determine the median. Tell me what you find as the median.

AnimeGhoul8863:

ok im here sorry i was looking for a web site

AnimeGhoul8863:

umm ok so if im right

AnimeGhoul8863:

the first one the median is 36

AnimeGhoul8863:

second one is 25

AnimeGhoul8863:

ok so am i right?

563blackghost:

that's right! now we need to find the median of Q1 and Q3. To do this we need to find the median on either side of the median. Do you understand what I mean?

AnimeGhoul8863:

kinda not really can u explain

563blackghost:

List the set in order here.

AnimeGhoul8863:

like each number in order

AnimeGhoul8863:

Set 1: 34,35,35,35,36,36,36,38,38 Set 2:20,22,24,24,25,25,26,50,65

563blackghost:

AnimeGhoul8863:

563blackghost:

563blackghost:

Q3*

AnimeGhoul8863:

UMMMMM

AnimeGhoul8863:

37 and 38

AnimeGhoul8863:

how did i do

563blackghost:

Q1 was already found as 35. So we only need to find Q3, so it is 37 :) Can you find Q1 and Q3 of the second set?

AnimeGhoul8863:

set 1 35 and 37 set 2 23 and 38

AnimeGhoul8863:

ok so am i right

563blackghost:

let meh see...

563blackghost:

That's right! Not to find the interquartile range you simply subtract Q3 by Q1! So find the difference of the quartiles.

AnimeGhoul8863:

Set 1: 2 Set 2: 15

AnimeGhoul8863:

@563blackghost

563blackghost:

CORRECT!

563blackghost:

Now you need to make the box plot for it.... |dw:1516129643325:dw| and from this determine if they are symmetrical.

AnimeGhoul8863:

UGHGHGHGGH soooo much

AnimeGhoul8863:

im confused on what to do now

563blackghost:

you just need to list the sets in a box plot, the above picture is a setup...

AnimeGhoul8863:

|dw:1516130041324:dw|

AnimeGhoul8863:

like this

563blackghost:

well one for each set.... and it needs to be on a number line....

AnimeGhoul8863:

im confused can u show me what u mean

563blackghost:

like this.... EX. |dw:1516130440333:dw|

AnimeGhoul8863:

huh i still dont get where it goes im not putting the pic as my answer so i need something different

563blackghost:

well i cant draw it out for you, you have to put it together. you already have all the data you need. Set: Minimum: 34 Q1:35 Median: 36 Q3: 37 Maximum: 38 Set 2: Minimum: 20 Q1: 23 Median:25 Q3: 38 Maximum: 65 Just make it into a box plot.....

AnimeGhoul8863:

ok thank you is that all i have to do

563blackghost:

yea just put it into a box plot, and analyze. Part 1 is already done!

AnimeGhoul8863:
