DESCRIPTIVE STATISTICS USING EXCEL

PART B.

QA).
The pie charts show that a higher percentage of the male gender has tried the product in comparison to the female gender. Over 50% of both genders have tried the product. However, the fact that the percentage of males who tried the product is higher, suggests that gender does play a role in whether the people will try the product. Yet the role genders play is small, because the difference between the percentage of females who tried the product and males who tried the product is small at only 7%.

However, since the graphs do not compare the genders within the total sample surveyed and are only a percentage of each specific gender, more information is required to answer this question with more accuracy. Another pie graph could be made to show the percentage of males and percentage of females who tried the product, as a percentage of the total sample surveyed. This would give a clearer picture of the role that gender plays, in whether gender plays a part in determining if people will or won’t try the product.

QB).
Both genders have a higher mean than median. The income mean is slightly higher for the male gender than the female gender. The mean for males is 44,760 and for females it is 44,095. This is because more males were surveyed than females. The mean is a measure of central location for income in the data but although the income levels surveyed for both genders are the same, the male gender’s mean is higher due to the higher number of candidates surveyed. Therefore, a second measure is used to determine the income central location and this is the median. The median is 37,500 and is the same for both genders. This shows the true measure of central location and is not influenced by the number of candidates in the gender sample as the mean is.

The fact that the mean is higher for the male gender than the female gender tells us, that the...

Existing Trade Relationships & Future Potential3:
Russia and European Union are Ukraine’s first and second largest trading partners.
Ukraine does not have a FTA with India yet, still India stands second in terms of Pharmaceuticals exports to Ukraine,
next to Germany.
Ukraine has a DCFTA and Most Favoured Nation treatment with Germany. In our business,
heart drugs exported from Germany or France can be a major competitor to our generic drug Atorvastatin.
Future potential of Ukraine’s trade relationships depend on how the economy develops in the next few months,
and European Bank for Reconstruction and Development

Descriptive Statistics Population - a set of all possible observations. Sample - a portion of a population. We often use information concerning a sample to
make an inference (conclusion) about the population.
Parameter - describes a characteristic of the population, eg: the population variance Statistic- describes a characteristic of a sample, eg: the sample variance
Frequency Distribution and Histograms Class - a collection of data which are mutually exclusive Frequency distribution - a grouping of data into classes Relative frequency distribution - calculates the number of data in a class as a percentage
of the total data
Shapes of Distributions and Histograms
A histogram is symmetrical if one half of the histogram is a mirror reflection of the other Non-symmetrical distributions are said to be “skewed”
a) Skewed to the right (Positively skewed) Mode < Median < Mean
b) Skewed to the left (Negatively skewed) Mode > Median > Mean
c) Symmetric Distribution Mode = Median = Mean
Measures of Central Tendency: The Mean, Mode and Median The mean is the average of scores: Population mean: μ = Σ xi/N
Sample mean: x = Σ xi/n
The mode is the value that has the highest frequency The median is the middle value of data ordered from lowest to highest The median and the mode are relatively less sensitive to outliers.

Descriptive Statistics and Mathematical Foundations
Part I: Pie Chart & Bar Graph
This information regards T-100 Domestic Market’s boarding information during the previous year for the top seven airlines in the United Sates. According to the data Southwest Airlines boarded 81.1 million; Delta Airlines, 79.4 million; American Airlines, 72.6 million; United Airlines, 56.3 million; Northwest Airlines, 43.3 million; U.S. Airways, 37.8 million, and Continental Airlines, 31.5 million (KU, 2014).
This is ungrouped data that needs to be grouped into a pie chart and a bar graph. The bar graph and pie chart both lists nonmetric (qualitative) descriptive statistics. The descriptive statistics are called, ordinal statistics which rank each airline from highest to lowest or lowest to highest annual boarding information (Black, 2012). The pie chart and bar graph summarizes the top seven airlines previous years boarding data. First, I will discuss the pie chart. The pie chart below shows the percentage breakdown of each airline’s annual boarding information. Each of the breakdowns represents the magnitude of the whole pie chart in percentages (Black, 2012). As you will notice that the leaders in the airline industry is Southwest and Delta Airlines with 20...

1 - Produce the relevant descriptive graph and table to summarise the MODE variable (labelled Control: Completes by phone/mail/web). The MODE variable summarises the different ways that each institution completed the survey. Write a paragraph explaining the key features of the data observed through the output.
The distribution of the surveyance mode which was conducted for a sample of 2000. The mode is displayed in the above chart. The most common primary mode was the web (53.9%) it was above the average. The second and third in common was the Mail and the Phone – Full mode at 24% and 16.3% respectively, very few people uses the Phone – Short method (5.9%)
2 - Produce the relevant descriptive graph and table to summarise the OPSEXTOTM variable (labelled QB5b_num_mal. Male outpatients – Total). This variable measures the total number of male outpatients at each institution. Write a paragraph explaining the key features of the data observed through the output
The distribution of male outpatients at each institution in a sample of 2000 is displayed in the above histogram. The distribution is positively skewed with 50% below 96 cases or less. Typically male outpatient cases were between 30 and 223 with mean at 191.62 and standard deviation of 349.62. However there were quite a number of outliers with 3 significant outliers above 4000 cases in ID 2926, 7251 and 6751 and there were a number of institutions with...
