Tugas Personal ke-4
Minggu 7
1. Apa keuntungan dan kerugian yang akan anda peroleh, apabila penelitian anda menggunakan pengambilan Sample?
Sampling is the process of selecting sufficient number of the right elements from the population. The major steps in sampling:
Define the population
Determine the sample frame
Determin the sampling design
Determine the appropiate sample size
Execute the sampling process
There are 2 major types of sampling probability and non-probability sampling
The advantages and disadvantages are:
Probability Sampling:
Advantages:
High generalizability of findings
Easy to use if sampling frame is available
Most efficient among all probability designs
In geographic cluster, cost of data collection are low.
Cost-effective. Useful for decisions relating to a particular location
Offers more detailed information on the topic of study
Disadvantages:
Not as efficient as stratified sampling
Systematic biases are possible
Stratification must be meaningful. More time-consuming than simple random sampling or systematic sampling
The least reliable and efficient among all probability sampling designs since subsets of cluster are more homogeneous than heterogeneous.
Takes time to collect data from an area
Original biases. If any will be carried over. Individuals may not be happy responding a second time
Non probability Sampling:
Advantages:
Quick convenient, less expensive
Sometimes, the only meaningful way to investigate
Very useful where minority participation in a study is critical
Disadvantages:
Not generalizable at all
Generalizability is questionable; not generalizable to entire population
Not easily generalizable
2. Coba anda terangkan mengenai simbol-simbol ini μ, σ, dan σ2! Digunakan untuk apakah simbol-simbol ini?
μ is used to measure population mean:
The population mean of a property is equal to the arithmetic mean of the given property while considering every member of the population. For example, the population mean height is
