The 9% task of stage 3 needs you discuss standard deviation and how it can be used in research methods,
For most students the easiest way to do this is to discuss sample estimates using a data set that is similar to the data set below
For the stage 3 9% task you have to discuss the theory of quantitative methods
Or if this is too difficult discuss ALL the following simpler ideas , this will be much easier if you follow all of the instructions given in the rest of this document
* fact that different samples give different results.
*estimates have the normal distribution which can be completely described in terms of the mean of the estimate and the standard deviation of the estimate
* discuss some methods are not valid, The method does not do what it is supposed to do.
*Many estimates normally distributed even if the estimate are not valid
* Why you need to follow a standard format when presenting your results in a journal article
*The standard error of the estimate is the standard deviation of the estimate
*If someone has experience with simulations they will understand probability value was developed by people Ronald Fisher that understand the concept that different samples give different results , Ronald Fisher had a much better understanding of the reliability of using samples than normal people. He could approach the problem deductively, He could work out the distribution of samples before any samples were observed. Normal people have to copy Ronald Fisher instead of coming up with their own solutions to the problems caused by the fact that different samples give different results.
This is similar to the fact that a anyone with actual experience using google knows that if Google start competing with your Business then you should change Businesses because the people at Google are better than you,
For example
In 2005 the head of the major Australia phone company Telstra was Sol Trujillo, Heembarrassed himself by stating he could stop google taking his business away and he used the phrase Google Schmoogle , You dont have to know exactly how google works to know that many people thought head of Telstra was crazy to say Google Schmoogle that the head of Telstra was wrong, You do not need to fully understand a simulation of many samples that gives percentile plot similar to the z chart to understand that people will think you are crazy if you dont copy the quantitative methods from other journal articles when you write your own journal article
What to do with the 1000 sample proportions (phat) file page 1 of 5
Open the excel file enable editting and content and type your student number into cell a2
Paste in the chart showing the population and the first 2 samples
What to do with the 1000 sample proportions (phat) file page 2 of 5
Also paste in the summary of the 1000 sample estimates
Paste in the summary output and demonstrate you know how to calculate the mean and standard deviation of the 1000 estimates of sample proportion by hand
