Advantages and disadvantages of systematic sampling?
Advantages 1.It is very simple to use. 2.It also saves time and cost. 3.It checks bias in subsequent selections of samples. 4.Its variances are most often smaller than other alternative sampling technique,when it is suitable to use. Disadvantages 1.There is the possibility of losing vital information from the population. 2.It may not be possible to select the required sample size if the population is too small. 3.It may not be good for periodic data.
Why its is necessary to use sampling in statistical investigation?
Sampling gives good insight of the choosen sample
How to reduce sampling error?
The only way to get rid of sampling error is to use the entire population under study. This is usually impossible, so the next best thing is to use large samples and good sampling methods.
What are the different non-probability sampling techniques?
The related web sites give a good idea of the types of non-random sampling. These include snowball, convenience, quota, self-selection, diversity, expert, and others. Non-randon sampling is usually done because it is less expensive, easier, and quicker than random sampling.
When graphing why should you draw a smooth line that reflects the general patter rather that automatically connect the data points?
It is not true to say that you should automatically draw a smooth line. It depends on what you are attempting to do. A smooth line may be a good indicator of a trend but such a line is useless if you want to find out whether or not there is any periodicity in the data. For the latter you must join the data points and look for periodic patterns.

What is the significance of sampling in research and what are the characteristics of a good sample?
Sampling is important as data collected is used to test the hypothesis. A good sample is a true representation of the general population. In addition, it should be flexible and focus on the research objectives.
Example of panel sampling?
A good example to panel sampling will be sampling the performance of a group of companies in a specified region. This way they the samples can be revisited at a later stage thus panel sampling.

When sampling is more appropriate than a census?
Yes. A sample only provides data from some of the population and is then extrapolated to the whole population; this assumes that the sample is taken equally from all possible datum points across the population - this cannot be guaranteed. A census provides data from all of the population so it is 100% as accurate as the data reading - whether the data collected is accurate or not depends upon what the data is and how it is obtained.
