I would like to ask if my target population is all the public listed property companies in Malaysia, what will be my sampling frame??
Is that okay to say the sampling frame will be restricted to the existing database of annual reports for public listed property companies available in Malaysia?
OR is there any alternatives?
Besides, I would like to know how should I choose my sample size? because the population is too big?
I am no expert on statistical methods but I have always found the following useful.
In relation to your query “Besides, I would like to know how should I choose my sample size? because the population is too big?”. This is where random sampling comes in. A truly random sample should be statistically valid. Take a look on YouTube and the internet to help you use an electronic method for random sampling (you might have to allocate a number to each company and then the program will select the numbers for you randomly).
There is a section in the guide about sample size.
