@mildblue...i heard the same thing.some people have seen their names true true!!..i wonder when they intend to release the list and by that i mean the "original list" not the "edited list"..God de sha!!

@kemzo..just type "MOE update" in the search input box and look for "MOE training info update group" from the result.shldnt be too hard to find..

for all those who were at agidingbi for the one month training u can join us on facebook using "MOE trainning info update"...we intend to share ideas, gather and seek what is ours before those on the "corridors" of power substitute us.there is no doubt we worked a whole month for this and thus we deserve it.the previous set did the same and they were heard.so instead of sittin at home doing nothin join us

actually i have this web catalogue/dictionary project im to design. Something similar to www.naijalingo.com so im still contemplating on the best cms to use..any suggestions??

thanks for ur response...which do u prefer using,i intend making a dictionary website.

please i would like to learn joomla or wordpress as soon as possible,anyone with free materials or videos..abeg help a brother out!!

hello all...i see myself as an "intermediate" web designer.i wld love to design an online catalog/dictionary,with words and their meaning.the site will also contain user accounts where users can login,request for meaning of certain words and chat..something similar to www.naijalingo.com which cms wld be preferable??

whatever man!!!...as for wizzy and dbanj nd deir "careers"?.as long as Nigerians prefer to "dance to beats" and dont give a damn about "lyrics" these two dudes will definately stick around for a while..

we rounded up our exams at agindigbi on sunday...for those non-education applicants...expecting the final list on the 2nd...God help us all.

ishmael: Hope u now understand the concept of dependent and independent variables?

Yeah i do...thanks...the whole statistics thing is new to me..its interestin tho..good to have gurus like u and alethia in tha house

aletheia: ^
Taking it some few steps further:
Let's fit the regression equation in order to help Jayjuice. . .I usually use R for most of my statistical work so. . .these commands in R:

year=1:5
amount.per.year=c(1000,1300,1800,2000,2200)
eqn=lm(amount.per.year ~ year)
summary(eqn)

. . .will produce the following as part of the output:

Coefficients:
            Estimate Std. Error t value Pr(>|t|)   
(Intercept)   730.00     106.61   6.847  0.00638 **
year          310.00      32.15   9.644  0.00237 **

Recall the regression equation: y = a + bx where y is the dependent (or predicted) variable which in this case is Amount, a is the Intercept, and b is the slope or regression coefficient and x is the independent (or predictor) variable, which in this case is Year. Plugging in the highlighted values from the output above gives a regression equation:

                           y = 730.00 + 310.00*x

And so substituting the x=6 and x=7 respectively gives you your predicted amounts for years 6 and 7.

In R predicting for years 6 and 7 is sort of:

predict(eqn, as.data.frame(c(6:7)))

Though this technically is how it should read:

> year=append(year, 6:7)
> predict(eqn, as.data.frame(year))
   1    2    3    4    5    6    7 
1040 1350 1660 1970 2280 2590 2900

But bear in mind that strictly speaking. . .

thanks alot..i really appreciate

ishmael: Hope u're ok with the Chi-sqr test problem?

yeah im ok with that thanks....i appreciate..but as for the linear equation,how can u differentiate ann independent var from a dependent var generally

ishmael: Hope u're ok with the Chi-sqr test problem?

yeah im ok with that thanks....i appreciate

one last question mr ishmael..i have a problem identifying the dependent and independent variable in the regression question below...question: a motor produces
electric motor for power
valve in a construction
company. Thee plant manager
thinks the growth in sale will
continue and he wants to
develop a long range forcast
to be useed to plan facilities
requirement for the next 2
years.sales record for the
passt 5years have been
accumulated.
Yr amount
1 1000
2 1300
3 1800
4 2000
5 2200
a:identify the dependent and
independent variable
b:fit the regression line
c:estimate the sales for the
next 2 years...

Jayjuice: ok...i just need to know ur table values...what values did u use to find ur expected frequence (fe)?

no problems man..thanks..i got the same answer as u,thanks alot

ishmael: i have solved the problem but don't have a way to upload it now. The chi sq value is 341.59 and from table chi sq(0.05), with 1 df = 3.841. i hope i get a way to upload it for u to see the computations. Regards.

ok...i just need to know ur table values...what values did u use to find ur expected frequence (fe)?

ishmael: Sleep dey worry me now, let's make it 2mrw pls.

no problem..thanks

this is to be solved using the chi-square formula..i realy dont understand it....."in a study to determine iff
there is an association
between alcohol consumption
and cigarette smokers a
researcher collected the
following data from 1090
respondent. Those who take
alcohol and
cigarette-580,those who take
alcohol only-40, those who
take cigarette only-200,and
those who take neither 270.
Is there any association
between them".........im supose
to usee the (o-e)2/e
formula,but im kinda
stuck...any help??

people people please when arre they releasing the yaba tech pume results??

when r tha results goin to be released?

Jskill: . How far?

didnt see it there...double checked!

@jskill..i will be goin there 2moro by 2..waz told to come for my letter.will check forr ur name when i get there

please house,where can i go to register,i recieved my message very late..any alternative...
