S1 STATISTICS, CODING?

[trolololama]

i was talking to my friend the other day, and she told me we have a chapter called coding! what is coding? do we even have that (cie)?

 

[Rocking]

Yes there is!
Dd ur teacher not teach u or r u self taught...?

my teacher didn't teach it! do you happen to have any notes?

 

[ZaqZainab]

what is it
all we have is

1. Representation of data
2. Permutations and combinations
3. Probability
4. Discrete random variables
5. The normal distribution

 

[Rocking]

Its a part of representation of data

 

[Rocking]

I dont hav any notes per say but if u want i can help you out wherever u need help
try doin a few qs frm the past papers

 

[Rocking]

which variant will u be doin btw?

This is just a sub topic in the mean median mode chap there are many questions of mean and standard deviation which we have to solve using coding method in past papers

Q2

I can do this question and i have no idea what coding is

 

[omaaaar]

I can do this question and i have no idea what coding is

Do you use this formula to solve this question sigma(x-a)/n +a this is what we call coding method

 

[Rocking]

I dnt use this formula though i get the ryt ans

Can anyone help me with continuity correction plz....i'm confused when to add or subtract those limits.....plz help.....giving As this 22nd

Q2

Did u do this question? I mean did u attempt it? I know how to find the mean and var from the coding given..but how do i convert it back into the coding if i am given sigma x etc etc? Somewhat what this question asks for. Any help?

yeah
