Statistics Review Questions - Essay Example Correlation is a method to measure the association in between two variables. When we compare the correlating scores of two variables, we are trying to determine whether the variables are related to each other or not. The purpose of doing correlations is to allow us to make a prediction about one variable based on what we know about another variable.  Ã‚  Ã‚   A frequency distribution is the tabulation of raw data obtained by dividing it into  classes  of some size and computing the number of data elements (or their fraction out of the total) falling within each pair of  class boundaries. A frequency distribution can be modeled as a  histogram  or  as a pie chart (Frequency Distribution). A pie chart shows the differences between two separate variables or subjects. A pie chart is a graph that is in the shape of a circle which represents a total of 100%. Other variables or subjects are shown on the chart with respect to their relative percentages to the whole. The different subjects are shown in different colors and the size of each subject in the pie is proportional to the percentage of the subject. A bar graph shows raw data and it is designed to show different values of two or more subjects but instead of using the pie to represent data it uses horizontal and vertical bars that represent a different value. The bar graph has numbers along the side of the bars to indicate the value of the variable and there are scales which show what variable is being measured. The difference between the pie chart and the bar graph is that a bar graph is capable of showing change over time. While a single pie chart cannot show changes over time by itself, it can only represent the given percentages at a fixed point in time. A graphical display of a  frequency table is called a frequency polygon. The X-axis has the intervals shown on it while the number of scores in each interval is represented by the height of a point located above the middle of the

Proposal - Research Paper Example Chalk Lines Exhibits intends to plan and manage this exhibition in a thoroughly professional way. The services of the staff and volunteers will be solicited and optimally administered to achieve the exhibition objectives. Special arrangements will be made for people with disabilities. Efforts will be made to assure maximal attendance and participation of the people of Brisbane. The event will be one of the first, showcasing a range of international, national and local artists in this genre. 1.0 Business Structure The Street smART is intended to be an exhibition exclusively associated with the contemporary graffiti, stencil and poster art. This exhibition will be organized and coordinated by Chalk Line Exhibits, a non profit, and incorporated organization in Brisbane. The sole purpose of Street smART is to facilitate an engaging platform for both the people of Brisbane and the invited international, national and local artists, where they can perform and experience the varied facets of the contemporary graffiti, stencil and poster art. One essential aim of the organization is to educate the local youth about the showcased art form and to encourage them to actively participate in and visit art events, exhibitions and galleries. The administration and staff at Chalk Line Exhibits is dedicated to make this exhibition a big success in the context of the envisaged goals and objectives. 2.0 Macro Environment Varied macro features at Brisbane make it an ideal venue for an exhibition of such nature and content. 2.1 Demography Brisbane is one of the most populated cities of Australia, with a major chunk of the population being urban and young (the targeted segment) (ABS 2011: Online). Brisbane is also a female majority city, which is most suitable for Street smART, as women have been found to have a greater predilection for art exhibitions (ABS 4172.0 2007, p. 13). 2.2 Cultural and Social Environment Brisbane being a cosmopolitan and modern city with its quintessential di versity and openness is inherently more accepting of change and novel trends. Thus, the populace at Brisbane could positively be expected to be more interested in and receptive of relatively new visual art forms like graffiti, stencil and poster. The cultural and social makeup of Brisbane portends an impressive attendance and participation. 2.0 Art Attendee Chalk Line Exhibits well understands that the art scene in Australia is defined by a unique mix of traditional art forms and novel approaches and trends (Australian Government 2011: Online). So the organization is dedicated to invest the financial support extended by varied public and private bodies to support and promote the upcoming art form of graffiti, poster and stencil. Hence, Chalk Line Exhibits intends to be very professional, efficient and accountable in the context of the exhibition under consideration (The Courier-Mail 2007: Online) 2.1 General Population Profile of Brisbane In 2009, the population of Brisbane stood at 2,004,262, out of which 1, 009,923 were females and 9, 94,339 were males (ABS 2010: Online). Thus, Brisbane is a female majority city. This is good for the exhibition as studies have shown that urban women are more likely to attend art exhibitions (ABS 4172.0 2007). Also, people between 15 years to 24 years of age constituted 15.3 percent of the populace (ABS 2010: Online). As this exhibition is particularly targeted at the youth, this translates
