## Extract of sample "Sampling then write the topic by your own"

Sampling Part One In the first sample, the first 20 were considered because each of them is equally representative and that they were easily available. Convenience sampling technique comes in handy due the fact that data can easily be collected and analyzed. A major disadvantage is that sometimes it fails to represent the total population (Thompson 14). Another disadvantage of this method is that respondents may be biased. This could amount to accidental sampling. The ids of the students picked were as follows:

The number of days absent was fewer.
In the second sample, students were picked randomly; the first and the last ten students were considered. The students were chosen as follows:

Here, the students were chosen systematically. The sample of students picked were those falling between ids 21 to 40. This was because the number of days absent was evenly distributed. Again, there was need for an average that is closed to the total population’s average.

Average number of students absent: 126/20=6.3; this number was higher than the total average. This is due to the fact that the sample chosen represented the highest number of absentees.
Convenient samples can easily be assessed; they are not involving. In this sampling technique, data is easily gathered and analyzed. A major risk associated with this method is that it is not representative of the whole population (Thompson p16). Respondents can sometimes be biased. Moreover, there may be overrepresentation and underrepresentation of some members of the sample.
Simple random sampling has a major advantage; respondents are selected randomly, so the results may be close to average. Every segment has an equal probability of being chosen. It reduces biases associated with overrepresentation and underrepresentation (Thompson p24). A major disadvantage of this method is that all members of the population may have to be listed; which could be quite cumbersome and time consuming.
Systematic sampling uses fixed intervals with a stated staring point. It has the same advantages and disadvantages as simple random sampling. In all the three sampling techniques, the sample interval was ten.
Part Two (A)
The sampling interval in this second part is ten.
Below are the five simple random samples considered: 5-24; 25-44; 45-64; 65-84; 81-100.

The average number of absentees is distributed around the mean for the total; in some samples, the average is slightly higher; in some samples, it is slightly lower.
Specify your six different estimates of absenteeism. How do they compare to the population value? How much variation do you observe across your six samples?
The greatest variation is (7.5-5.95) = 1.65; the least is (5.95-5.75) =0.20.
Part B 2
The samples will be taken at the following intervals:
1-40; 11-50; 21-60; 31-70; 41-80; 51-90

Average: 289/40= 7.1
When a larger number is considered (40 instead of 20), the variation reduces. The average values are closer to the average for the total than when a sample of 20 is used. For instance, the largest variation is 7.1-5.85=1.25, and the smallest is 5.85-5.5=0.3. Larger samples have less variation. They give better results, which mean the average are closer to the whole population’s average. It leads to generalization of the whole population (Thompson 34). Systematic sampling improves estimates since it representative samples are considered for best estimates.

## CHECK THESE SAMPLES OF Sampling Assignment then write the topic by your own

In the very beginning the business would be limited to importing homemade ups namely bed covers, curtains, pillow covers, quilts, towels and the like. The market for such goods in the United States is not only large but rather diverse because consumers from all buying strata are present in the market. Moreover the market’s large size means that imported textile products have a low chance of getting stuck up in warehouses because there are not enough right kinds of buyers (Arthur and Sheffrin). Another advantage in starting such a business could be local contacts in the South East Asian region who could supervise the manufacturing and supply efforts. 2.

### Freedom, I Write Your Name

...Freedom, I Write When we consider the ramifications for the of restricting all considerations of justice to individual intention and self-ownership, we find ourselves considering Libertarianism. Libertarianism seeks to limit the central power of the State as severely as possible, leaving all or almost all matters of justice in the hands of individuals or extremely localized small groups of individuals. In essence, there are two modalities of this philosophy of Statehood. Some libertarians adhere to the “entitlement theory of justice”. Its major exponent being the philosopher Robert Nozick, it holds that every individual has the rights to life, liberty, and property, where these are rights of non-interference, or entitlement...

### Sampling

...Sampling A research study is expected to help in understanding the nature of relationships shared by variables not just for the studied individuals; but for the entire population. But in order to apply the conclusions of any study, it is important to ensure that the selected sample is actually representative of the population from which it comes (Frankfort-Nachmias & Nachmias, 2008). There are different ways of choosing a sample, and each method is useful in responding to certain types of research questions. The different sampling techniques can be divided into two groups – probability sampling techniques and non-probability techniques (Frankfort-Nachmias & Nachmias, 2008). Probability techniques are based on the principle that each member...

### Sampling strategy

... fifty (50) of such new mothers. The rationale for using random sampling technique in the quantitative survey and selecting fifty (50) respondents is that surveys require the collection of data from a relatively larger setting and as such the sample size must be large enough to give a true proportionate representation of all people within the population. For the qualitative focus group study, a purposive sampling strategy shall be used to select members in the sample size. A purposive sampling strategy do not allow for equal probability of selection of members but comes with its own advantage which is, a specific classification of respondents who are thought to be suitable for the provision of certain data will be selected (Bushman, 2007...

### Sampling & Generalizability

...Shampoo al Affiliation Sampling and Generalizability According to the article, quantitative research refers to the practice of quantifying the behavioral orientations of human beings with the intent of comparing either between various groups, or afore and after interruptions, such as emotions, thoughts and behaviors. Precision is one of the most vital aspects of quantitative research (Weir et al., 2002, p. 3). To suitably address the concerns of precision, analysts must also appreciate that there are numerous levels of measurement or variables. These include nominal, continuous, discrete, interval, ratio, and ordinal variables. In the article, Physical Activity in Pregnancy: A Qualitative Study of the Beliefs of Overweight and Obese...
