In probability sampling it is possible to both determine which sampling units belong to which sample and the probability that each sample will be selected. Thanks in advance Reply. I am showing what I observed from the question. Loo kim hooi on July 27, at CS on June 12, at 3: Random sampling is the purest form of probability sampling.
You can also include the info name, interest, and others of the respondent. Non-probability Sampling The following sampling methods that are listed in your text are types of non-probability sampling that should be avoided: Construct three confidence intervals for the mean time spent daily by students in your school to access the social media. Chew on June 11, at 8: An individual group is called a stratum. Sample does not have known probability of being selected as in convenience or voluntary response surveys Probability Sampling In probability sampling it is possible to both determine which sampling units belong to which sample and the probability that each sample will be selected. How about Question No.
Construct tspm confidence intervals for the mean time spent daily by students in h school to access the social media. Siti Aisyah on September 17, at The following sampling methods are examples of probability sampling:. Tiffany Cheah on March 9, at 7: Will sir provide some guidence for the semester 2 project work. 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.
Of the five methods listed above, students have the most trouble distinguishing between stratified sampling and cluster sampling.

Give at least five different representations of a simple discrete function. To convert to degree.

Stratified Sampling is possible when it makes sense to partition the population into groups based on a factor that may influence the variable that is being measured. The data on time spent daily by students in school to access the social media is recorded.
So think about your sample size in terms of what you know about the population and decide whether the sample is large enough. Share your papers Please share your school or your collection of trial exam papers to me.
Jin on June 12, at 6: How about Question No. Because x is equal to all real number. X on May 1, at 4: For the total number of combinations, please refer to your school teacher. Chew on June 11, at 8: Sampling Methods can be classified into one of two categories: So, how to continue with comments the validity???

I am not going to discuss the questions in class. Different school teacher have different requirement on the non-mathematical part Introduction, methodology, and conclusion.
If you never compare with the exact value, it is no point for you to comment about T1 is greater than T2. The data are collected from a random sample from large population all students from KL. 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. 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 mzth us how large courseworrk should be.
Can i know how to write for introduction, methodology and conclusion? Please do it yourself. Selventhraan on March 21, at 8: The question mention use alternative method to find T1 n T2 The question oso didnt ask for the value of T right?
There is a probability of 0.
