## Extract of sample "None"

Statistics XL10: Project Brief introduction of the project The project seeks to understand the scores obtained by students in the U.S based on gender and State in which the student comes from. The dataset comprises of 4 variables namely; gender of the student, State in which the student comes from, the number of hours the student takes to prepare for a Mathematics test and the scores obtained by the student in a Mathematics test. In total, 30 students took part in this survey. Data was collected both from the exam registry and one on one with the students. The registry provided us with the students scores while the students were asked to state the number of hours they took to prepare for the test and the state in which they come from.
Qualitative and Quantitative Variables
a) Histograms

Based on the above histogram, the most important metrics to study would be the mean and also looking at the parametric tests since from the histogram, the variables shows that they follow a normal distribution
c) Bar graph and pie charts of the qualitative variables
i) Bar graph for the gender
ii) Pie chart for gender
iii) A bar graph for the states
iv) A pie chart for the States
Clearly from the charts presented above it is clear that in terms of gender more male respondents (students) took part in the survey as compared to the female respondents. 57% (N=17)of those who took part were the male respondents while the female respondents were 43% (N=13).
In terms of the states, Alabama State had the highest number of the respondents while California had the least number of students interviewed in this survey. 30% (N=9) of those who took part in the survey were from Alabama, 27% (N=8) were from Arizona, 20% (N=6) were from California while 23% (N=7) were from the State of Illinois.
d) Boxplots

... Should social security be overhauled, reformed or terminated? What policies do you feel are important in evaluating this? Explain and support you reasoning for selecting the particular policy issues. Social security should be reformed. It should not be terminated because social security serves as a safety net for any financial contingencies in the present as well as in the future (i.e. retirement). The reason it should be reformed is because it now faces a “projected long term funding gap” (Aaron, 2011 pg. 386). If no reform will be instituted, it is projected that the social security will have to cut its benefits by 24 percent in 2037 just to keep itself afloat (Aaron, 2011). This would be disastrous to pensioners because... Should...

... Socrates about Wisdom The ancient Greek philosopher Socrates did not leave written treatises. His teachings and ideas of wisdom can be found in the treatises of his pupil Plato, in which Socrates is the protagonist. Based on the study of Platos dialogue called Apology, it can be argued that Socrates understands wisdom primarily as ethical knowledge. Moreover, Socrates considers himself a wise man capable of a critical attitude to the existing knowledge while looking for the real truth. To begin with, Socrates is convinced that the truth requires knowledge of the distinction between good and evil actions and behavior (Plato 28). Thus, Socrates sees wisdom primarily a practice of the moral life, in which the main role is played... Socrates...

Above all, a poet did not have to identify himself or herself with Europe, but be an American.

Package is also important because of the exclusive control that the product storeowner has over it. Unlike brand that depends on influence for creation... summary...
