What kind of sampling technique are you using (simple random‚ stratified‚ systematic‚ cluster‚ multistage‚ convenience)? Answer: For all students I would use the convenience sampling. The reason
Explain and briefly distinguish between simple random reasoning, systematic random sampling, stratified random sampling, and cluster sampling. Which of these techniques is designed to guarantee representativeness? How? What is your decision regarding the null hypothesis? Given the following hypotheses:...
A simple random sample of 700 individuals provides 200 Yes responses. a. What is the point estimate of the proportion of the population that would provide Yes responses (to 2 decimals)? b. What is you Determine the probability that in a sample of 100, the sample proportion is less ...
Figure 3. HPV genotypes of random samples and controls amplified by NMPCR as detected in agarose gel electrophoresis. (A): Example of first-round amplification (outer-PCR reaction) using 10 degenerated primers, generating 450-bp amplicons. (B): Examples of first-round amplification of the inter...
Now having said all this, it's important to remember two more things. First, what sounds good or bad is a subjective thing; you might prefer the bassy sound of an MP3 player with simple earbuds for EDM (electronic dance music) and a CD player with fine headphones for classical symphonies...
In a nutshell, this is the probability that the observed difference (or a greater difference) in scores between the experimental and control group could occur due to random chance, if the experimental stimulus has no effect. For a more drastic example, an experiment could test whether wearing ...
Sampling Procedures There are many sampling procedures that have been developed to make sure that a sample really represents the target population. Simple Random Sampling In simple random sampling‚ every individual in the target population has an equal chance of being part of the sample. This...
PPS, or probability-proportion-to-size sampling, is a sampling technique in which a fixed population is used. In PPS, the probability of choosing a unit is in correlation to its size. Answer and Explanation: The answer isfalse If the...
In order to increase the responsiveness of a forecast made using the exponential smoothing technique, what can we try? Describe with regards to smoothing constant value. Compare random selection and random assignment. Define each term and an ...
B. Explain what is the sampling methodology. C. What are all of the components to sampling when creating a research study? D. What are the limitations of sampling? E. What are the statistical te Explain and briefly distinguish between ...
