We reject H0 if the test statistic is less than 7. Sample has a known probability of being selected Non-probability Sampling: With stratified sampling one should: Mulan on September 21, at 8: Learn how your comment data is processed.

You can find the sample of the results below. The data on time spent daily by students in school to access the social media is recorded. There is a probability of 0. Chi-squared test is hypothesis test. So my conclusion which one is more suitable?
Simple Random Sampling SRS Stratified Sampling Cluster Sampling Systematic Sampling Multistage Sampling in which some of the methods above are combined in stages Of the five mathh listed above, students have the most trouble distinguishing between stratified sampling and cluster sampling.
Cluster Sampling is very different from Stratified Sampling. Please refer the table below. We reject H0 if the test statistic is less than 7. 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. You can also include the info name, interest, and others of the respondent. Coursewogk on September 10, at 6: The survey was conducted using Google Form and all students are allowed to fill in the form with multiple times even though they have been warned to fill matg once.
The frequency distributions are tabulated as above. Get more references from Internet. Is the question 5 answer this short only? Construct three confidence intervals for corsework mean time spent daily by students in your school to access the social media. Can u give some tips about to how write the methodology?
The following sampling methods that are listed in your text are types of non-probability sampling that should be avoided:. Thank you for the reference for all of us form 6 marh.
The following sampling methods are examples of probability sampling: Stratified sampling works best when a heterogeneous population is split into fairly homogeneous groups. The sample size is sufficiently large.

It is mentioned in the post above. TJY on August 22, at 2: Mulan on September 21, at With p known or unknown? Then with p unknown, Ho is rejected at any level of sl except 0. These groups are maath called strata. Thanks for helping in doing the survey. The number of people wearing glasses in a family may be modelled by a binomial distribution.
Therefore the data i used above is taken exactly from the survey from students. Lim Jun Tong on September 2, at 3: An individual group is h a stratum.
