The data are sampled randomly because it avoids bias. When there are very large populations, it is often difficult or impossible to identify every member of the population, so the pool of available subjects becomes biased. Will sir provide some guidence for the semester 2 project work. The sample size is sufficiently large. These groups are then called strata.
U have to integrate it. You can download from padowan.
I never prepare full answer. Give at least five different representations of a simple discrete function. Under these conditions, stratification generally produces more precise estimates of the population percents than estimates that couursework be found from a simple random sample.

Chan Chee Sam on July 4, at 7: Your email address will not be published. Standard distribution is assumed as above formula.
Can i know the website you are using to plot the graph? If the population is very skewed, you will need a pretty large sample size to use the CLT, however if the population is unimodal and symmetric, even small samples are ok. Hi, thanks for sharing. The sample values are independent of each other.
Some ideas for you.
Can i know how to write for introduction, methodology and conclusion? Which functions are you referring? You can use the graph function in the excel. Give at least three different representations of a continuous function.

Learn how your comment data is processed. With cluster sampling one should divide the population into groups clusters.
Siti Aisyah on September 18, at 2: Although the Central Limit Theorem tells us that we can use a Normal model to think about the behavior of sample means when the sample size is large enough, it does not tell us how large that should be.
Please ask your school teacher for introduction, methodology, and conclusion. July on May 1, at Non-probability Sampling The following sampling methods that are listed in your text are types of non-probability sampling that should be avoided: An individual group is called a stratum.

Maath on March 21, at 8: For 3 a and bwhy the values for T1 is greater than the value for T2? In general a sample size of 30 is considered sufficient. Hello, I have question how can you get the T exact? Cluster Sampling is very different from Stratified Sampling. Chew on June 11, at 8: Sham on May 2, at
