Question

AP Stats Standard Deviation and Variance question @ShadowLegendX

Answer 1

So I had to do 3 problems where I had to find the range, sample mean, standard deviation, and variance. Then, I was asked to create a histogram of the distributions from those 3 problems. I'm not completely sure what they want

Answer 2

Yeah, whatʻs a histogram o-o

Answer 3

Gotta ask Google

Answer 4

It's kind of like a bar graph

Answer 5

Graphing...fun stuff ._.

Answer 6

I know how to create a histogram, it's just in this instance I'm not sure what they want me to do

Answer 7

Yeah I know, graphing...awesome...

Answer 8

You donʻt know what the distributions of those problems are?

Answer 9

I do, I just wasn't sure if you wanted me to put all of them down here cause it's a lot of numbers

Answer 10

woah deja vu

Answer 11

Anyway

Answer 12

If you know how to make a histogram, and you know what the distributions are, then I donʻt see what the problem is

Answer 13

Just create the graph, and supply the data

Answer 14

Okay so the distributions I got from the 3 problems are:
1. Range: 15.1, sample mean: 65.41, variance: 14.9, and standard deviation: 3.9
2. Range: 24.5, sample mean: 74.94, variance: 42.5, and standard deviation 6.5
3. Range: 46.1, sample mean: 65.41, variance: 160.2, and standard deviation: 12.7

Answer 15

So do I create a separate graph for each one?

Answer 16

For like A, B, and C?

Answer 17

A histogram for each of the questions to that problem

Answer 18

?

Answer 19

Yeah, because the original question wants me to basically describe what the graph(s) look like and compare them to each other

Answer 20

Yeah Iʻd create a histogram for each, just to be safe

Answer 21

The actual question says: Draw histograms of the distributions from Questions 1 and 3. (4 points)
A. How would you characterize their shapes
B. How do their means compare?
C. How do their standard deviations compare?
D. How do skew and range affect the standard deviation; does one affect it more than the other?

Answer 22

What grade are you in, might I ask?

Answer 23

I'm a senior in HS

Answer 24

mhm, hey Inky

Answer 25

Answer 26

Answer 27

Yes

Answer 28

Are you here to help

Answer 29

Answer 30

You know I can ez ban you

Answer 31

and I cannot easy ban you?

Answer 32

k wutever, just be nice

Answer 33

I totally didn't get bahrom's assistance in writing code that automatically suspends people

Answer 34

Totally didn't. It totally doesn't create a bunch of accounts and reports people en masse.

Answer 35

Never and won't ever happen.

Answer 36

It's like the hedgehogger except with reports. But it doesn't exist.

Answer 37

Mini, Iʻd just supply whatever data they ask for, as you said you know what they want, and then make the graphs, for each question that the ask for. When youʻre unsure about what they want, itʻs just better to be sure, play safe, and just give a lot of data, correctly formatted, in histograms in this case ;P

Answer 38

on a website with such a consistent uptime and great service like openstudy, they would never allow such an exploit. It simply wouldn't be possible. Nope. Nada.

Answer 39

PA?

Answer 40

mini, you know how to do a histogram?

Answer 41

He does

Answer 42

She actually, just for the record

Answer 43

don't bring PA in the picture, I am talking about openstudy alone. If PA were to exist (it doesn't) it wouldn't have community suspensions anyways

Answer 44

But yes I do

Answer 45

It does exist, itʻs just a graveyard, lol

Answer 46

wow shaddy, you made the same mistake as me. I always assume male gender and have to be corrected. Sigh.

Answer 47

We are too similar in some ways, it scares me

Answer 48

and if it *did* exist, I would be hypothetically calling you a graveyard right now. But it doesn't. So I didn't.

Answer 49

and I love AP stats because histograms are fun to draw. /sarcasm

Answer 50

I took myself all the way to the top, and got access to moderator accounts, lol

Answer 51

oh. wow.

Answer 52

Iʻm sorry, she*

Answer 74

LOL

Answer 75

Answer 76

@MiniMato , did you know that every post that we add to this discussion lags it by around .1 seconds?

Answer 78

I know, thatʻs why I didnʻt correct myself initially while I was writing it

Answer 79

but they really add up

Answer 80

Wow lol. And yeah I know what skewed histograms look like

Answer 81

trust me, experience

Answer 82

ok so you just have to draw the histogram and follow the instructions

Answer 83

I've noticed, it's getting hard keeping up lol

Answer 84

don't worry
