Testing of Proportions
While dealing with proportions in statistics, it is imperative that you should remember that there will be a hypothetical situation and research questions that are mostly answered will have hypothesis test for a single proportion.
A test of proportion is used for assessing whether a specific sample is representative of the true proportion from an entire population. To deal with this, both Critical Value and P-Value approach is used.
How to conduct it?
- There is a simple random sampling method that is available
- Sample has to include at least 10 successes and failures
- Population size has to be 20 times of the actual sample size
- There are specifically 2 outcomes that are attributed to this sample: Success and Failure
There are 4 steps that are to be found here:
- Initially the hypotheses has to be stated
- Next an analysis plan has to be formulated
- Next the available sample data has to be analyzed against the new backdrop
- Final results are to be interpreted and sample population has to be found.
Here are sums to give you a proper idea of this process.
