What advantage does chorionic villi sampling have over amniocentesis?
yes
What are the advantages and disadvantages of a time sampling observation in childcare?
Time sampling observation in childcare involves recording specific behaviors or events at predetermined intervals. The advantages include obtaining quantifiable data on children's activities and interactions, which can help identify patterns and inform targeted interventions. However, disadvantages include the potential for missing important behaviors outside the sampling periods and the risk of observer bias influencing what is recorded. Additionally, this method may not capture the full context of children's experiences and interactions.
What kind of errors arise in sampling?
sampling is a waste of time
What are the advantages and disadvantages of systematic sampling in statistics?
Hi, 1.The main advantage of Systematic sampling over simple random sampling is its simplicity. It allows the researchers to add a degree of system or process into the random selection of subjects. 2.Another advantage of systematic random sampling over simple random sampling is the assurance that the population will be evenly sampled. Disadvantage The process of selection can interact with a hidden periodic trait within the population.
What is the advantage and disadvantage of the convenient sampling?
Convenient sampling refers to using a sample group that is the easiest to gather. The advantage of this is that it is the easiest way to convene a test group. The down side is that the sample may not be representative of the population, so the results will be skewed.
Advantage of sampling?
The advantage of sampling in results is that it greatly simplifies results. If the sample is appropriately random, the results of the sampling will accurately represent the whole.
Advantages and disadvantages for probability sampling?

How soon in the pregnancy is chorionic villi sampling performed?
The chorionic villus sampling is performed by 10 weeks of gestation. The pregnancy can be safely terminated by this time, if necessary. That is the advantage of the procedure.
What are the advantages of time sampling?
It can observe behaviors in natural setting...or Observation can serve as basis for further assessment or to validate other assessment measures.
What are the advantage of sampling over complete enumeration?
more expensive , less expensive ,less time consuming and greater accuracy

What advantage does chorionic villi sampling have over amniocentesis?
yes
What are the advantage and disadvantage of sampling techniques?
Sampling techniques in research allow researchers to gather data efficiently and cost-effectively, providing a snapshot of a larger population. This can save time and resources compared to collecting data from an entire population. However, sampling techniques may introduce sampling bias, where certain groups are overrepresented or underrepresented in the sample, leading to results that may not accurately reflect the entire population. It is crucial for researchers to carefully select and implement sampling techniques to minimize bias and ensure the validity and generalizability of their findings.
What are examples structured observation?
Examples of structured observation include checklists, rating scales, event sampling, and time sampling. These methods involve systematically recording specific behaviors or events at predetermined intervals, allowing for a more objective and standardized way of collecting observational data.

What are the Advantage and disadvantage of purposive sampling?
Purposive sampling involves selecting participants for a study based on some characteristic that you know they have. There is nothing random about their selection - it was done with intent. An advantage of this type of sampling is that it allows the researcher to quickly hone in on the target population. A disadvantage to this form of sampling is that researcher bias can creep in to influence results, if subjects are not chosen very carefully.
