Sampling error concerns natural variation between samples is always present and can be described using probability Is this true?
No, it is not true. Probability can be used to describe some properties of the variation but not all.
Concept of Probability sampling and chi square test?
A probability sampling method is any method of sampling that utilizes some form of random selection. See: http://www.socialresearchmethods.net/kb/sampprob.php The simple random sample is an assumption when the chi-square distribution is used as the sampling distribution of the calculated variance (s^2). The second assumption is that the particular variable is normally distributed. It may not be in the sample, but it is assumed that the variable is normally distributed in the population. For a very good discussion of the chi-square test, see: http://en.wikipedia.org/wiki/Pearson%27s_chi-square_test
Why do you use Stratified sampling?
They have used Stratified Sample. Design because stratified sample is a sampling technique in which the researcher divided the entire target population into different subgroups, or strata, and then randomly selects the final subjects proportionally from the different strata. This type of sampling is used when the researcher wants to highlight specific subgroups within the population. So in this Research this technique is used by the researcher.
Is p value a descriptive statistic?
No, it is not. A descriptive statistic is a measure such as mean, standard deviation etc., computed from a set of observations. A p value is something that is obtained by computing a test statistic (using a formula which may involve mean, variance etc.,) and finding the probability of obtaining a value as great as or greater than the one actually obtained. In other words, a p value is a probability and must lie between 0 and 1 whereas a descriptive statistic is not a probability. It is just a number used to describe a specific characteristic of a set of sata.
What type of sampling is used to estimate the percentage of defects?
random sampling
How is probability related to statistics?
Probability is related to statistics in a direct manner. When one is doing a research for statistics, probability has to be used especially in sampling a small region.
What tools are used in descriptive research?
The tools used in descriptive research are pictures. Captions and headlines in newspapers are also a good source for descriptive research.
Parts of descriptive research?
Descriptive research is used to describe characteristics of the subjects being studied. Descriptive research is used for frequencies, averages and other statistical data collected during research.
What the methods being used in conducting a research?
Quota sampling stratified sampling random sampling convenient sampling cluster sampling semi stratified sampling stratified quota
How probability sampling is used?
Probability sampling is used to select a sample from a population in such a way that every individual or element in the population has a known and non-zero chance of being selected. This method ensures that the sample is representative of the population, allowing for generalizations and statistical inferences to be made with greater validity and accuracy. Probability sampling techniques include simple random sampling, stratified sampling, cluster sampling, and systematic sampling.
Should standard probability sampling techniques be used in content analysis?
yes
Which research is best suited for descriptive conclusive research?
When the research objective is quite clear, the research being performed is of quantitative type and the sample being used is quite big then conclusive descriptive research design is used.
What type of research is used to gather information of describe a phenomenon?
descriptive research
What type of research is used to gather information or describe a phenomeon?
descriptive research
Characteristics of descriptive research?
Descriptive research is used to describe characteristics of a population or phenomenon being studied. It does not answer questions about how/when/why the characteristics occurred. Rather it addresses the "what" question.
Which of the following are the three basic types of research used in psychology?
1)Basic( Pure )Research:2)Applied Research:3)Action Research:4)Historical Research:5)Descriptive Research:
What are the parts of descriptive research?
Descriptive research includes observational methods, case study methods, and survey methods. They are used to describe situations instead of make predictions about them.
