yes. DB Question is due on wed.THANKS
this is from my peers
BUSN 311 Unit 1 DB Cherry Iott AIU Observational study is a method of data collection which involves a process of watching any given any type of situation and recording the data that is observed. The disadvantages of the observational data method are that some of the research can be conducted to a subject to the researchers. They also may not be enough information given. The advantages of observational data method are that the researcher will experience their firsthand and is easy to do. There are no calculation needed to see the outcome of what the researcher is trying to achieve. The second method is Questionnaires: In order to collect data, it is normally comprised of the questions that need to be clearly constructed. The advantages of the questionnaires is that it gives immediate feedback and they also have a way to rate the scale which is created during the evaluation. The disadvantages of the questionnaires is that if it is done in person the individual who is being asked the questions which can be influenced by the way the person who was conducting the survey. The mass mailing is of the return rate is low in the percentage. References: Editorial Board.

THIS IS THE DATA SET TO HOMEWORK ASSIGNMENT IP
I JUST WANT TO KNOW DID YOU RECEIVE THIS.
k you will need that for homework assignment Ip which i will sent to
you on friday.thanks
A little hint for your discussion board posts:
We want to reference other sources that is a great plan! However we want to make sure that our work is our own work and thoughts. When you submit your post you get a similarity score. In general for discussion boards we want to be sure that this is under 25%. If it is higher than 25% it means you are using to much information from other sources or to many direct quotes. So look at your score, use it to your advantage and go back and change/edit your post so you have less quotes or direct information from other sources. Put some of the information in your own words, summarize, paraphrase. Its great to use these sources and I encourage it but we also want to make sure that you are assimilating the information into your own thoughts as well! Remember direct quotes are RARELY appropriate unless the credibility of the author adds to an argument. This is not the case in mathematics so try to use as few direct quotes as possible!
similarty score was 29%
DB Question that you gave me on 3/21/12.THANKS
Unit 1 - Accessible Statistics - MAIN POST
American InterContinental University
Statistics is a field that collects and interprets quantitative data on any subject in order to describe traits of a state's population.
Body (4 paragraphs)
Two different methods of data collection are observational data and census.
Observational data is a process where the observer observes a given situation in order to record and collect the information observed. The observational data has been used in north Atlantic region to understand why extra tropical cyclones are the main reason of intra-annual climate variability. From 1957 to 2000, the observers registered green house gas concentration. Observers also recorded the life cycle of extra tropical cyclones. In addition, they emphasized on the level of the sea temperature surface in North Atlantic Ocean also called North Atlantic Oscillation (NAO). These observational data in this case allowed observers to interpret and explain why the number of intense cyclones increases now days (Sienz, Schneidereit, Blender, Fraedrich, 2010).
The pro of an observational data is that information is collected when and where an activity or event is taking place. The disadvantage is that the information collected by observational method cannot be generalized to a larger population.
Another data collection method is census. It is a method of collecting data by survey on an entire population at a point time. The US census bureau uses this to determine US population including sex, age, race, ethnicity and household. It was a formula that each household fielded and sent back to the bureau via mail (United States Census Bureau 2010, 2011)
The advantage of census is that there is a great chance to have feedback from the population. However, census is not practical in most study because it takes time and it cost. (Meradorf, 2009).
Observational data and census are two collection data method used in statistic. Observational data is applied on a small group while census needs a large population.
