...Store’s Credit Card) We will take a look at three different variables at this time. Location The location variable has three subcategories which include rural, urban, and suburban. This variable is looking at where customers live. A pie chart is a circular graph which divides information into sections based on numerical proportions. Frequency distribution tables allow us to look at variables and their frequencies (or how many times the variables occur). Frequency Distribution Location Frequency (# of Customers) Urban 21 Suburban 15 Rural 14 Interpretation: Based on the information shown in both the pie chart and the frequency distribution chart, we can see that more of the customers (21/50 = 42%) are from urban areas. Suburban areas are next with (15/50) 30% of the customers and rural areas have the least amount of customers with (14/50) 28%. Credit Balance The credit balance is the amount of funds that are currently charged to the credit card. Credit balance is a quantitative variable which means we actually can get an exact numerical value. A histogram is a graph of frequency distribution using rectangles.

...credit balance. The first variable analyzed was that of Location. The location data is a categorical variable. Which was further broken down into three subcategories? These subcategories are Urban, Suburban and Rural. A frequency distribution and pie chart are given as follows: Frequency Distribution: | Location | Frequency | Urban | 21 | Suburban | 15 | Rural | 14 | The pie chart and frequency distribution, proves that the largest number of customers are those in the rural category (42%), followed by those in the suburban category (30%). There are only 28% of the customers falling into the urban category. The next variable analyzed was Size. It is a quantitative variable. Central tendency, variation and a bar graph were calculated for the Size variable. The mean household size of the customers is 3.42. And the median of the data collected is 3, the mode is 2. The standard deviation is rounded to the nearest one hundredth and is 1.74. Upon reviewing the frequency distribution chart and the bar graph, the largest number of customer household size is 2.

...| A Study on ‘Socio-economic Status of Rickshaw Pullers in Dhaka City’ | Course Name- Business Statistics ( F-503) | | Submitted to:Dr. M. Jahangir Alam ChowdhuryProfessorDept. Of FinanceUniversity Of DhakaSubmitted By:Md. Shafiul Azam (ID#26059)Student of ‘Business Statistics’ Spring, 2014EMBA (Finance) ProgramUniversity Of Dhaka Date Of Submission: 30th April 2014 | 1. Introduction The rickshaw is a small-scale local means of transport. It is generally a pedal-driven vehicle i.e. it is run by human power. But at present rickshaw with an electric motor is available to assist the puller. The rickshaw was built in the 1880s and was first used with regularity starting in 1929 in Singapore. Six years later they outnumbered pulled rickshaws. Cycle rickshaws were found in every south and East Asian country by 1950. By the late 1980s there were estimated 4 million cycle rickshaws in the world. Rickshaw is the most popular mode of transport in Bangladesh and are available for hire throughout the country. Dhaka, the capital of Bangladesh is known as the "Rickshaw Capital of the World". They were introduced here about 1938 and by the end of the 20th century there were 300,000 cycle rickshaws in Dhaka. Approximately 400,000 cycle rickshaws run each day. Cycle rickshaws in Bangladesh are also more convenient than the other public modes of transports in the country namely auto rickshaws, cabs and buses. They are mostly convertible rickshaws with...

...Section 1-2 Ex. 26 Surgery vs. Splints – A study compared surgery and splinting for subjects suffering from carpal tunnel syndrome. It was found that among 73 patients treated with surgery, there was a 92% success rate. Among 83 patients treated with splints, there was a 72% success rate. Calculations using these results showed that if there really is no difference in success rates between surgery and splints, then there is about a 1 in 1000 chance of getting success rates like the one obtained in this study. a. Should we conclude that surgery is better than splints for the treatment of carpal tunnel syndrome? It would be unfair to make such a conclusion. There are pieces of data missing: age of the patients, current health conditions of the patients, and prior treatments the patients had for this condition. b. Does the result have practical significance? The study did not generate enough viable results to make it practical for any use other than to ensure that a greater investigation should be conducted to verify the differences between the two treatment methods. These results were most likely voluntary responses, making the data gained, fairly useless. c. Should surgery be the recommended treatment for carpal tunnel syndrome? No, there is no defined level of severity for each patient. Without that information a logical recommendation for treatment cannot be assigned. Section 1-3 Ex. 30 Cloning Survey – A Gallup poll of 1012 randomly surveyed adults found that...

...Economics Theory 1. Describe The Fundamental Economic Problem? Any economic system has to deal with some fundamental economic problems. These problems are common to all economies. The following list gives the Four most fundamental economic problems faced by any economy. 1- What to produce? 2- How much to produce? 3- How to produce? 4- For whom to produce? How these problems are dealt with differ from one economic system to another. OR The fundamental economic problem is simply the problem facing a society on how it chooses to utilize its finite amount of labor and resources to satisfy the seemingly infinite number and variety of human wants and needs. Economics is the way in which ruling bodies prioritize their resources and strive to ascertain which needs and wants of the populace are most deserving of being satisfied. The fundamental needs of society tend to be the ones that are most frequently addressed; such as food, clothing, warmth and shelter. As such, most economies across the world today attempt to consistently provide for the needs of the people in their society. Once the basic needs of humanity are addressed, the population drives demand for any extra goods and services. A personal computer is an example of an item somebody wants above basic needs. This demand is met by companies making computers and selling them to the public. The issue of choice is also important. Businesses realize consumers have a choice about which items to demand and as such...

...Qualitative vs. Quantitative Analysis When research is being conducted you must gather data. “Data are the facts and figures collected, analyzed, and summarized for presentation and interpretation” (Anderson, Sweeney & Williams, 2005, 5.) You must differentiate the type of data before you can analyze it. “There are basically two ways to go about an analysis, qualitative analysis and quantitative analysis” ("Difference between qualitative," 2011). “You can use both qualitative and quantitative reports to track the work performance of individuals, business units and your workforce as a whole” (Ciaran, John). Each type of data has its own advantages and many times analyzers use a combination of both types of data to make decisions. Qualitative and quantitative data are important to gather because they provide different outcomes. These are often used together when analyzing in order to get a full picture of a population. Qualitative data is either on the “nominal or ordinal scale of measurement and may be nonnumeric or numeric” (Anderson, Sweeney & Williams, 2005, 7.). This type of data focuses on interpreting raw data. This type of data is also known as “categorical” data. Qualitative data can be used to evaluate investments or other business opportunities. This type of data can also assist when it comes to decision making. Some believe qualitative analysis is “the foundation of a broad array of investment and financial decision-making methods” ("Qualitative analysis...

The data set includes 50 customers with gross income ranging from $20,000 to $79,000 per year. Compilation of the data into a frequency/relative frequency table (see below) reveals that the greatest frequency and relative frequency of the store’s customers is found within the $30,000 to $49,000 range. Fifty-two percent of the store’s customer base gross income is found within this range. First and third quartiles have been calculated to be 33 and 57 respectfully. However, no outliers have been identified within the data set.
