Survey Sample Size Essay Example for Free

Survey Sample Size Essay This essay will have two parts one will discuss three different surveys and the second will be a survey that was performed by the author. The subjects of the surveys will be Entertainment, Political, and General. We will analyze the surveys that do not have the population that were surveyed. Introduction The entertainment survey will be a survey that was conducted by Universal UK, was conducted in the Britain, and is about the movies they have vivid memories pictures of in their mind. (Macnab, 2013) The Political survey was conducted by Gallup Wellbeing, is about older United States employees. (Ander, 2013) Number 3, the survey is from Gallup Wellbeing also and is about how female veterans rate their life. (Meyers Liu, 2013) Entertainment Survey Universal UK conducted this survey in order to decide which movies would sell the most if put on DVD’s. To describe the number of participants Macnab said, â€Å"The participants were people across Britain†, but no number is mentioned. (Macnab, 2013) Without the number of people surveyed, we cannot calculate if the participants were the correct amount. It was thought that the memory of the movies was considered as, â€Å"escapism†, but through the survey results, it was discovered that it was the reverse. As it showed the participants did not use the movies to escape life’s problems, but they were used to face them. (Macnab, 2013) It was as if the participants gained confidence during the viewing of the movie. Through doing the survey the company discovered the movies to use for DVD’s, and the ones that had an impact on changing people’s lives by giving them self-esteem and confidence . Confidence and raising self-esteem levels of the viewers helped some viewers improve their lives, which is why they remember the movie. . Political Survey The political survey researched Federal employees to compare the younger employees to the older employees and Federal Employees to Non-Federal employees. (Ander, 2013) The evaluation was to compare who thought; they used their strengths while on the job to do what they do best the most. (Ander, 2013) One hundred fifteen thousand (115,000) people participated which when divided in half (because there are both Federal Employees and Non-Federal Employees) gives us 57,500, which would not be an appropriate amount of participants per population. It is because of this class that this author can say the participants were not significant for the population. We have learned that the targeted survey group must be appropriate for the population results. If they researched this to the total population in the United States, the participating group should be at least 100,000 per group. This survey showed the results that the Federal employees who were 18-25 years old were the biggest percentage who said yes at 85.0%. (Ander, 2013) The Non-Federal employees results are participates 65 years and older were the biggest percentage who said, â€Å"Yes† at 86.0%. (Ander, 2013) This was unexpected because it was thought the older employees would have the higher percentage for both. The least satisfied for the Federal employees were the 65 years and older at a 77.4% and the least in the Non-Federal employees category were the 18-29 year old group at 82.1%. (Ander, 2013) This survey proved the Federal Government could help their older employees more and the Non-Federal employers could help their younger workers more. (Ander, 2013) General Survey The general survey is about female veterans of the U.S. military having a much better outlook on their lives then the Male veterans. The survey was composed of 353,561 Americans. (Meyers Liu, 2013) There were 48,690 respondents, which were affiliated with the military of the 353,561 participants. The results showed that female veterans rated their lives as, â€Å"thriving† were 54% while the male veterans at 44%. (Meyers Liu, 2013) The researchers say one of the reasons for the 10% gap is due to the optimistic view of females compared to the males. Based on the total sample of national adults, the researchers comment that they can say with 95% confidence that the margin of error is  ± 1 percentage points. (Meyers Liu, 2013) The sample size for this survey was appropriate for the population. Overview The first survey did not mention any numbers as for the survey size or the population, so there is no way to tell if the survey size is appropriate for the population. The second survey did mention 115,000-survey size, which is divided in half because there are two groups. This gives us a 57,500-survey size per group for the population. Using the population of the United States, we should have a 100,000 per group at the minimum. The third survey of the veteran females’ life satisfaction is the only one that has the correct amount of survey size. This survey size is353,561 of the population of military affiliates, which is a proper size per population. Application: Copy of Survey Application: Results Chart 1 This chart show the ages of the participants, the 35-44 age categories has the most participants, which is 30% of the total 20 people. The lowest percentages of participants are the two categories of 18-24 and 65-74 with a percentage of 10%. The people ages 35-44 are the largest group of people to watch the movie. Application: Results Chart 2 15%,30%,20%,35% This chart shows the number of participants that read the number of books 1, 2, 3 and the series of 4 books. As you can see, the participants that read the series are 7, and are the highest in percent’s also at 35%. This means that most of them read the series. The least of the participants (3) read only the first book at a percentage of 15%. . Application: Results Chart 3 50% of the participants thought the movie was only somewhat close to the book. 30% thought the movie was not Application: Surveys and Business The survey above could tell the movie directors that they should make the rest of the series closer to the books. The participants seem to think they could have made the movie more like the books. There was a lot of story line missing of which some was important to the story to be complete. Some of the participants said they were very disappointed, because for the books to be so good and the movie to be so bad there had to be something somewhere that missed the whole story’s meaning. Conclusion In conclusion, we have studied various surveys showing how some have not had a survey group that was the correct size for the population. In order for the data to be accurate, the researcher must have the proper sized survey group for the population they are researching. Statistics cannot be correct if the data is off.

Theodor Herzl: Father of Zionism? Essay example -- Theodor Herzl Essay

Theodor Herzl: Father of Zionism? Theodor Herzl is often referred to today as the Father of Zionism, a man known for his role in the establishment of a homeland for the Jewish people. His most famous pamphlet, The Jewish State, inspired thousands of Jewish men and women from across the world, although particularly in Europe, to leave their homes to realize the glory of creating their own homeland in Palestine. While Herzl was originally a believer in the gradual assimilation of German and Austrian Jews into the European cultural world, the growing anti-Semitism within Europe led him to believe that the only solution to Jewish ostracism was the creation of a separate state for Jews in Palestine. Although Theodor Herzl became, over the course of his lifetime, a man who held a crucial role in the creation of a state that Jews across the world could take pride in and refuge from the prejudice they faced throughout the European world, he was never truly a believer in the traditions of Judaism and was primarily concerned with the necessity for the â€Å"reformation† of the Jewish culture instead of the founding of a prejudice-free environment. European anti-Semitism, a condition that influenced his own views on his culture, dominated the world that Theodor Herzl grew up in. In a world dominated by prejudice, even Herzl, who defended the rights of the Jews, viewed them as a people who had been corrupted by years of exile and persecution. The leading intellectuals of the time believed the Jewish people to be a race of money-lenders and usurpers with no capacity for change and as such were a class to be ostracized (Kornberg 21). In contrast, Herzl believed that while his people may have held the stereotypical Jewish vices of greedine... ... own culture. Although he held that the European Jews were exposed to extreme anti-Semitism, he also believed this oppression had caused them to become a people worthy of the stereotypes placed on them by the prejudiced European Christians. Herzl grew to believe that it was only though a complete disassociation with these peoples would the Jews again become a race of people worthy of European respect. Theodor Herzl is somewhat of an enigma in that he is a man who dedicated his entire life to the cause of improving the lives of his people for reasons that many would find to be prejudiced themselves.

The Key to Happiness

The key to Happiness Is the glass half empty, or is it half full? A true optimist would say that the glass is half full. That is because an optimist will always lean towards the more positive option. Optimism is defined as â€Å" the inclination to look at the bright side of any situation, and expect the best possible outcome from any series of events. Anyone can be optimistic, some people choose optimism as a way of life, it can reduce stress producing a better quality of life, and if used on a regular basis optimism can be the key to happiness.Anyone at all can practice optimism. To be an optimist all one has to do is choose to see the positive side of a situation. Its like the saying, â€Å"Count your blessings. † A person may feel that they have nothing to be positive about, but when they are reminded of the positive things in their lives they tend to forget about the negative. Optimism can be developed when one has realistic goals and expectations. Optimists don’t fall into a trap of feeling hopeless, instead they strive for growth and positive change. Being optimistic is not about pretending that everything is okay.It is about thinking positively when things go wrong, learning from them, and moving forward. Optimism can be incorporated into any activity that takes place on any given day and if used on a regular basis, people will see a positive change in their lives. Optimism can produce a better quality of life. Anxiety and negative emotions can take its toll on the body, it can affect your cardiovascular and your immune system. Having an optimistic attitude can protect against these effects. Research has shown the people who choose to have an optimistic attitude about their future behave differently.Optimists have been known to exercise more, smoke less and eat healthier. When they fall ill, optimists are more likely to participate actively in their treatment. Some would say, â€Å"A healthy mind, means a healthy body. † Optimists are better able to handle difficult situations with the ups and downs of daily living. Optimists tend to be more creative and harder workers. They are not afraid of there pasts or their futures. They understand that not everything can be changed, they accept that and move on. Optimism is the key to happiness. It helps us appreciate everything we have in life.It is within appreciation that we find happiness. Optimism is full of positive possibilities. It leads a person to happiness by reducing stress and pulling people towards a more positive future. Helen Keller wrote an essay on Optimism in 1903. She wrote, â€Å"Optimism is the faith that leads to achievement. No pessimist ever discovered the secret of the stars, or sailed to an uncharted land, or opened a new doorway to the human spirt. † This is a true statement because having faith in ones self will encourage that person to set new goals in their lives and better yet help them have the will power to achieve them.It is wi th a pessimistic attitude that people give up too quickly on their goals or possibly never even set them to begin with. With optimism comes hope, perseverance, and self confidence. It is with hope that one strives for a better tomorrow. It is perseverance that wills a person to keep trying. Confidence gives people the ability to believe that everything will turn out all right. All of these things portray optimism. Making yourself happy by seeing the better side of situations in life will lead to success. Optimism in everything they do will bring out the best qualities and skills in a person, and this will lead to true happiness.
