what the fuck is slope b?

the slope the number in front of 'test 2' in the regression fit box at the bottom of the plot (1.203)

>>8283714
rate of change formula

>>8283714
Looks like 1.203 but that software is garbage

>>8283720
You're an idiot if you think that it's not already given to him right there.

>>8283718
>>8283721
So then whats the 30.04 for?

>>8283737
thats the intercept (what test 1 equals when test 2 is zero), also its -30.04

>>8283714
Is this using EViews? I hate that goddamn program.

>>8283740
Oh OK thanks. So that's what the y axis is equal to at zero. So then if I had to work out what someone would get on test 2 when they got 63 on test 1 how would I use that to work it out?
>>8283744
No it's minitab but it's not very helpful

>Minitab

why are you using that piece of shit.

Also -30.04 is your b slope from my memory of minitab

1.203 is the y intercept.

>>8283792
But someone said that the 1.3 value is the slope b
...

>>8283838
The slope is increasing, it is clearly a postive value.

Line equation is y =mx + b

In this case, b is the intercept and m is the slope. Just plug in numbers.

>>8283871
you're fucking retarded, read my post here >>8283721 minitab has done the calculations for him the value is right fucking there he doesnt need to plug in shit.

>>8283878
Please stop being such an aggressive dick. I appreciate the help but is that really necessary?

>>8283725
its not though you stupid american

>>8283916
fuck off read this post >>8283871

y= mx+b

1.203 IS the slope b value you stupid europoor, you can't prove me wrong either because it's literally right there.

Proof Europoors can't into maths.

Whether 1.203 is the y intercept I don't know though as I'm not familiar with minitab

>>8283920
I'm from Brasil idiot

First and foremost, what the fuck is a slope b.

I have NEVER heard that term before, is it exclusive to minitab? I know that the slope in a normal y equation is the last variable, is that what it means this time?

slope b is actually the b part of y = mx + b?

Or am I missing something here? What does OP need to plug in if that's not it because seriously, as far as I'm aware and from what I've learnt, 1.203 IS the slope, and it also happens to be the b value of the equation y = mx + b

Did this monkey get ahold of one of the Internet devices brought by the 1st world Olympians?

>>8283923
microcefalia confirmed

>>8283925
slope is m

b = f(0)

>>8283944
>slope clearly has a positive gradient
>it's actually -30.04

Brazilians are not smarter than americans.

>>8283951
>>it's actually -30.04

yup, b = f(0)

>>8283954
Thats fucking wrong,

Go to the bottom of this page and read the last 2 lines

http://support.minitab.com/en-us/minitab/17/topic-library/modeling-statistics/regression-and-correlation/regression-models/slope-and-intercept-of-the-regression-line/

Tell me that 1.203 isn't the slope now you shitty hue

>>8283942

at least fucking spell it right

>>8283968
yup,
f(x) = 1.203x - 30.04

slope = 1.203
slope b = -30.04

>>8283975
sorry, haven't been myself after zika

File: y is b plus mx in this case.png (29KB, 741x235px) Image search: [Google]

>>8283984
Are you fucking stupid or something??

Read this.

it states that the first value b0 in this case is the intercept

it states b1(x) is the SLOPE

the equation op posted is -30.04 + 1.203

Hue is proven wrong once again.

So does minitab show the equation as y = b + MX?

>>8283999
>>8283984
How can both values be slopes? What about the intercept

What is going on?

>>8283714
Use matlab or excel while solving linear regression

>>8284027
I can't I need to use minitab

>>8283714
>what the fuck is slope
it's the slant of your forehead
fgt pls

Are Brazilians and Americans this retarded?

>>8283714
Just look at it.
1.203 sounds good.

Rise over run is about 50/40 which is 1.25. That's with rough rounding.

>>8284092
You're retarded, its -30.04

how can the intercept be 1.203 when at 60 the y axis is at 42/43?

>>8284092
OK I'm going to assume >>8284127 is a troll.

So would that mean if someone got a score of 63 on test 1 they would have a score of 64 on test 2?

>>8283999
>what is the commutative property of addition?

>>8284180
I think you meant 74.
I don't know what these tests are, I was just talking about the slope.

Shieet.
Right
Take any Test2 value, multiply by 1.203, subtract 30.04 and you have Test1

The reverse would be Test 1 value, add 30.04, divide by 1.203 to get test2

I haven't read the thread so someone might have said this pls no bully

>>8284200
To me, the value of a slope would mean its "slope" (rise over run)

I learned maths in a different language though, so it could be something else

>>8283878
Both of those posts are mine. Can provide pic if you haven't fucked off in embarassment

>>8283925
Software line excel and their knockoffs use b as the slope.

The variables don't matter, the relations do.

You could say y = x + ¿ if you wanted to.

>>8284003
Apparently

>>8283925
No, the slope is how much x changes when y changes.

y = x is a line from the origin going up and left at a 45 degree angle.
y = -x is a through the origin going down and to the right.

Since the line is clearly up and to the left in op pic, it's positive, meaning it can't be -30. Therefore, the equation must be
y = 1.203x - 30

This is literally middle school math.

>>8284204
I meant to quote >>8283725 as my post you faggot.

Read this post >>8283999 its straight from minitabs website and says clearly that b0 IS THE Y INTERCEPT and b1 IS THE SLOPE

Since fucking when was the slope connected with x?

y = mx + b
mx = intercept
b = slope

Why else is it asking for the "slope b" ??

fuck off

>>8284211
So you're telling me that 1,203 is "slope b" when I've just said above that it can't be 1.203 because mx is the intercept

if that's the way you're typing it the slope b is -30

because y - mx + b

the way it is in OPs picture shows him that its y = b + mx because according to you "mx" = "1.203x" and "b" is "-30.04"

Are you seriously telling me that's correct?

>>8284211
So 1.203 is the value of slope b?

>>8284274
whoever wrote the question was a slop.

the slope is the rate of climb
the intercept is where the line hits the y-axis

the general way to write the formula is
y = ax+b

So, 'slope b' is a criminally sloppy and retarded
name for the intercept.
Whoever wrote the question should be fired and whipped in public.

This thread is hilarious

>>8284296
I'm with you, this is gold
What >>8284282 meant to say is that -30.04 is you're slope b

>>8284274
Yes, trust me. Otherwise you'd get negative test scores, which isn't possible

>>8284383
>Implying the slope = test scores
Are you retarded?

>>8284200
This is fucking wrong too
Op your better off going to reddit this thread is filled with idiots

>>8283714
ask yourself why the fuck you can't use R

>>8284508
Where does r come from ops question

>>8284533
He's trolling

>>8284460
No?
Why are you putting words in my mouth?
If the equation was Y = -30x + 1.203, a test score on test 2 of 60 would be - 180 on test 1

>>8285820
thats exactly the format it is in though.

y = mx + b where the slope b is 1.203 and m aka the intercept is -30

Does it look to you like a test score of 1.203 on test 1 is 0 on test 2?

no.

>>8285897
b is the intercept

>>8285897
test 2 = x
test 1 = y

1.203*(test 2 score) - 30 = test 1 score

a score of 1.203 on test 1 would be a score of 30 on test 2

>>8285973
So I've been reading it wron all along? then whats the fucking slope?

also OP disregard my posts I suck cock apprently

>>8286090
the confusion here is that the question asks for slope b.

the general form for the line equation is
y = mx + b
where m is the slope, and b is the y intercept
(what y is when x = 0)

when you said the slope b is 1.203 and the intercept is -30, that is correct, but in this case,
"slope b" is m
and b intercept.

you were right for the wrong reasons

Seriously surprised this thread is still going on.

I wrote down that "slope b" as the write sloppily put it is 1.203

And to work out a test 2 score when test 1 score is 63 would be (63+30.04)/1.203

Am I correct?

>>8286137
No and No.

>>8286137
You are correct.
Idk why you're being trolled so hard.
See my previous post

>>8286398
Thanks for not being a troll like the other guy, I understand it now.
