Methods Modeled as a two phase effort, this research project will initial employ quantitative methods to determine if a statistical significant relationship exists between how advanced and economy is and the age of its population. Two data sets will be analyzed with frequency analysis, bivariate linear regression, and hypothesis test based on interval analysis. The second, qualative phase of this research effort will employ a content analysis if authoritative literature sources designed to seek out links between older populations and current socioeconomic issues of importance affecting advanced economies today, and which will affect developing economies in the future. The first part of this research effort will seek to establish a …show more content…
The second set of data to be collected includes the ages of populations segregated by nationality. This data set is sourced from The World Bank as well. The categories employed are also defend by the World Bank: 0 to 14 years old, 15 to 65 years old, and over 65 years old ("World Development Indicators | DataBank," n.d.). Each nation has three data points, one each representing the percentage of each age groups within their population. Analysis methods employed are to include: A frequency analysis and analysis of distribution, depicted with histograms and box plots, portraying the distribution of the different age groups within the world population. Scatter diagrams to provide visualizations of the relationships between per capita GNI and the percentage of population in the three different age groups diagrams relating. Linear regression including trend lines, regression formals, and the coefficient of determination for each pair of variables visualized in the scatter diagrams. Cross tabulations, segregated into deciles, with individual cross tabulations for the four aggregates under study. A three dimensional bar chart, with accompanying data in tabular format visualizing the relationships between the mean percentage of age groups within the three income aggregates. Interval analysis with accompanying sample size analysis to provide margins of error based
The first variable considered is Location, a categorical variable. The three subcategories are Urban, Suburban and Rural. The frequency distribution and pie chart are included. Measures of central tendency and descriptive statistics are not calculated due to the categorical nature of the variable.
You are all interested in something. Explore the literature (magazines, books, web sites, etc) for your interest area and find an example of the use of graphical statistics. I suggest a Google search using the Images option, and select some interesting and visual display of data. Identify the related materials that support the graphic and containing some form of statistical analysis and/or display. Review your materials using the framework offered below.
A scatter plot diagram provides a graphical observation of how two different variables are related to one another. Looking at the data collected for credit balance of customers along with the data collected for income of customers, it’s easy to recognize that there is a correlation between the two variables. The linear positive slope indicates that an increase in the credit balance correlates with an increase in income.
Starting to look at individuals of note since going over everyone would take me all year. But first, the genders and my guess of age before I start with the individuals. Starting from the top left corner: male 70, female 30, male 25, male 40, male 50, male 60, female 50, female and another 50, Male 35, male 30, male 27, male 26, male 70, male 40, male 30. Now restarting at the bottom left corner: male 26, male 30, male 35, female 30, male 29, male 30, male 55, male 25, and male 35. As I stand here looking at this data, the vast majority are male and most look under 50 to me. The woman I chose as my focal point is in bright clothing with blonde, short hair and black sunglasses. The man next to her has a black overcoat with a beard that makes his mouth looks to be nonexistent. The man with the bright suit and the mustache two people away from the focal points reminds me the most of the 80's and my father's old mustache.
- Age and sex structure of a population: refers to the number or proportion of males and females who are in each age category, tells us about a population 's past trends in fertility, mortality, and migration, provides information about the population 's potential for
The information in this section of the AoA website brings together a wide variety of statistical information about this growing population. (Aging, 2013)
During orientation in my second year of Teach for America, my school district presented graphs and figures boasting improved standardized test performance and graduation rates. Teachers began cheering and patting each other on the back. Meanwhile, I squinted at the PowerPoint slide, trying to make sense of a glaring error in the bar graph displayed. If such an obvious mistake was overlooked, how could these results be trusted? For that matter, was the data responsibly collected? Information about student performance was too important to be handled haphazardly. I sensed that the results were not being diligently communicated to us; yet, I was unable to pinpoint how to improve the presentation. In that moment, I knew I needed to learn more statistics. The following spring while still teaching full-time, I took an elementary statistics course. I enjoyed it so much, I decided take more mathematics courses. Finally after years of searching, I found my true love: mathematics and statistics.
E. The age and sex structure of a population refers to the number or proportion of males and females who are in each age category. Age-sex structure tells us about a population's past trends in fertility, mortality, and migration. It also provides information about the population's potential for future growth. The greater the proportion of people in the younger-adult age groups, the greater the potential for more births and population
With all of this being said the chart basically discusses the percentage of age differences in students in college. A probability of older students is starting to increase versus the population of younger students. Older Americans that are going back to school is on the rise according to the chart and percentages it is slightly on the rise. Being an older adult in college it shows the persistence of older adults wanting a high
while going to the museum and looking into Ancient Egypt I have notice that one of the mummy had amulets all over. The amulets were in different size, shape, and colors. Ancient Egypt believe that amulets would protect the living and the dead. For example, Harwa an Dynasty 25 mummy adult in late period was full of Amulets. According to the display on the museum, amulets were used to wrap within the mummy’s bandages and had its own special function. For instance, the scarabs are a symbol of rebirth and resurrection. Scarabs is shape of a large dung beetle. Also, they gem cut the form of a scarab beetle or spread their wings and they would hieroglyphs on the flat underside. Furthermore, a scarab beetle would be portrayed as Ra also known as Khepri
In terms of independent variables, by referring to the Appendix, figure 1 reveals the summary of the sample; it also
Over the years, there have been major shifts within the United States in regards to its population. Statisticians have estimated that 20% of the population will be 65 years of age and older. There is an even
Having the distinct honor and privilege of serving as an international cultural ambassador and contributing artist has afforded me the rare opportunity to observe firsthand the perpetuation of African-American created art forms and social traditions around the world. In my professional development I have made it my personal mission to ensure that historic and modern Urban Dance forms are authentically shared, presented and celebrated. Sharing from this lens has allowed me to observe to the seeming disparities that result when authenticity and cultural reverence are relegated to the desires for mass enjoyment and profit.
According to the UN World Health Organization definition of aging over 65 years as "elderly", when the population of a region or country, the ratio of the elderly more than 7%, referred to as "aging society."
The biggest threat to humans today is the rapid growth of the human population. Not many people know about how over population is effecting the environment and the few people who do don't know what to do to help. Over population is the "greatest non-issue of the past 100 years" unless you count global warming (Blair 27). Over human population has been over looked for years. In order to solve this problem we must come up with a solution. There is not only one solution, but a good start is to make contraceptives more available for third world countries.
