@uri this is making me shiver already...
terenzreignz
  • terenzreignz
This is a long and annoying process... first you need to find the smallest and largest values....
uri
  • uri
lol,This is actually the first chapter which includes numbers,other is theory @terenzreignz

  • terenzreignz
yeah, I figured. it has been two years since I first read about this (it bored me to death)
terenzreignz
  • terenzreignz
but, I'll help you get started... first, the smallest and largest values?
uri
  • uri
Lol,like smallest to the largest number?
uri
  • uri
200 is the largest.
terenzreignz
  • terenzreignz
oh, well, sorting them from the smallest to the largest would make your job easier, but not REALLY necessary (for the moment). Yes, 200 is largest, the smallest?
uri
  • uri
136 looks smallest to me :D
terenzreignz
  • terenzreignz
Okay, now you need their difference...
uri
  • uri
difference,as in?
terenzreignz
  • terenzreignz
I meant difference of 200 and 136, but I think that's also not needed (in the book I read, I'd be told the number of intervals I should have, and not the width of each interval) Anyway, the width of each interval is 5, right?
terenzreignz
  • terenzreignz
Okay, first, you need to know the intervals... Intervals take the form, for example, the first interval is 136 - 140 that's an interval. Following me so far?
uri
  • uri
136 -140,what do we have to do..?
terenzreignz
  • terenzreignz
for now, it's just an example of an interval. you'll get it later :) It just means 136 to 140 now the WIDTH of this interval is 5, because there are 5 possible values 136, 137, 138, 139, and 140 okay? :)
uri
  • uri
We have to go from the smallest values to largest..? and the width is 5 so yeah..I get it.
terenzreignz
  • terenzreignz
Okay, so we need to identify ALL the intervals (that we need) starting with 136 to 140 What's the next interval? :)
uri
  • uri
141 -145.
terenzreignz
  • terenzreignz
That's good. Just name all the intervals (no need to post them here, I know you can do it) until you reach an interval that contains the highest value. that'd be 196 to 200, yes?
uri
  • uri
Yes,So waste of time so i have to see how many intervals there are altogether?
uri
  • uri
146 -150,151-155,156-160,161 -165,166 -170,171-175,176-180,181 -185,186-190,191 -195,196-200...:O
uri
  • uri
13 intervals,If I am not wrong?
terenzreignz
  • terenzreignz
nice SS uri. maybe I should unfan you to bring it back to yellow :D Just kidding Yeah, 13 intervals :) Ready for the next step?
terenzreignz
  • terenzreignz
Next step is the easiest and also the hardest :D
uri
  • uri
Yes,ready :)
terenzreignz
  • terenzreignz
It's tallying... so help me this task is taxing... so much work... anyway, you just have to tally how many in your data set (that large list of numbers you have) corresponds to each interval. For example, for the interval 136-140, you have 2 entries (if I'm not mistaken) You have one "136" and one "140" Now you have to do the rest for all the other interval >:) Good Luck...
uri
  • uri
um so the other interval is *141* and *145*
terenzreignz
  • terenzreignz
Not quite, I'm sure there are 142's, 143's, 144's... did it occur to you that these also belong in the interval 141-145 ? :D
uri
  • uri
I don't get this!! :(
terenzreignz
  • terenzreignz
don't worry... 141-145 that means all numbers between 141 and 145, including 141 and 145 themselves. I believe there are 6 of them in your data set... one 141 one 142 two 143's one 144 one 145
terenzreignz
  • terenzreignz
get it now? :)
uri
  • uri
There are 5 set in one..
terenzreignz
  • terenzreignz
huh?
uri
  • uri
wait..from 141 to 145 there are 5.
terenzreignz
  • terenzreignz
No, see, what you're asked to do is to find how many 141's, 142's, 143's, 144's and 145's are in your data set. I believe I have already found all of them ^
uri
  • uri
Oh how many in 40's?
terenzreignz
  • terenzreignz
not quite, because you don't count the 46's onwards (yet) only from '41 to '45
uri
  • uri
Why?
terenzreignz
  • terenzreignz
because the interval is only 141 - 145 remember? :P
uri
  • uri
Yes...so what do i have to do now?
terenzreignz
  • terenzreignz
tally the rest :D
uri
  • uri
Do one more for me..
terenzreignz
  • terenzreignz
sure :) The interval 146-150 okay? :)
uri
  • uri
Okay?
terenzreignz
  • terenzreignz
okay :) hang on...
terenzreignz
  • terenzreignz
I saw 8 of them.... two 146's one 147 one 148 one 149 and finally three 150's that makes 8 entries that fall within 146 - 150
uri
  • uri
Okay now let me try for 151-155.
terenzreignz
  • terenzreignz
sure :)
uri
  • uri
two 151 two 155 one 153 two 150 Um 7?
terenzreignz
  • terenzreignz
Yeah, 7 See? This is a horrendously annoying task :D Even though it's technically easy :P
uri
  • uri
Omg,I did it! Okay now let me do others fast!
terenzreignz
  • terenzreignz
I'm reposting the numbers here so I don't have to keep scrolling up and down... 200,196,192,188,186,184,180,178,191,187,183,179,177,175,173,171,169,158,156,173,150,157,155,153,151,148,146,163,159,155,151,149,147,145,143,141,158,154,150,156,144,142,140,138,146,153,150,143,136
terenzreignz
  • terenzreignz
Wait a sec, why did you count the 150's ? There were already accounted for in the 146-150 part..
uri
  • uri
Sorry 5.
terenzreignz
  • terenzreignz
and there are two 153's (don't feel too bad if you're getting this wrong. I'm getting this wrong too :P)
terenzreignz
  • terenzreignz
It's just a really annoying task.
terenzreignz
  • terenzreignz
This is why I hate stats :D
uri
  • uri
So there are 6? lol
terenzreignz

Hey @uri are you using chrome? Ctrl+F might be a godsend here :D
uri
  • uri
Yes,chrome why? :D
uri

I pressed it,i don't know what happened..o_o
terenzreignz
  • terenzreignz
ctrl + F and just type the number you're looking for. chrome highlights them B)
terenzreignz
  • terenzreignz
No, press and hold Ctrl and then press F
terenzreignz

196-200 one 196 one 200 that is 2
terenzreignz
  • terenzreignz
and we are done with frequencies, thank God... XD
uri
  • uri
Yaay,Thanks ;)
terenzreignz
  • terenzreignz
So, you have two columns now, one for the intervals... 136-140...etc One for the frequencies (the ones we were counting) You might have a column for the "Class Mark"
terenzreignz
  • terenzreignz
But don't worry, class mark is just the midpoint of each interval For example, the class mark of the interval 136-140 is 138
terenzreignz
  • terenzreignz
and so on.
uri
  • uri
Got you :3,So for 141 to 145 is 143 right?
terenzreignz
  • terenzreignz
... I can't believe you dragged me back into Statistics, I thought I had enough of this 2 years ago... (when I was 14 haha) anyway, it was fun though :3
terenzreignz
  • terenzreignz
and yes to the 141 to 145 things, the class mark is 143 :)
uri
  • uri
Lol,you're so...smart..
terenzreignz
  • terenzreignz
and you're so... persistent XD LOL good job for both of us, aye? :D
uri
  • uri
Wait,what does persistent mean,I mean idk...
terenzreignz
  • terenzreignz
Well, I think I'll call it a night... mind you, we just brushed the surface of Frequency Distribution tables, but thankfully we have done the more important parts (the rest is just computations) (persistent means persevering) anyway, I'm really tired :) I'm signing off for now ----------------------------------------- Terence out
