Median Voter Theorem On the spectrum of politics (or any other ideologically-based matter), personal opinions will inevitably vary from one extreme on the left to the opposite on the right. In a governing system such as that of the United States, where the population directly elects representatives to govern, the position a candidate holds on the spectrum pertaining to certain issues in relation to other candidates becomes increasingly important. Theoretically, two people coming from different

Statistics Investigation Into Height and Weight Relationship From the data I have received I have chosen to conduct an investigation comparing height and weight because I feel there much relevance between ones and height and weight. I have chosen to compare height and weight because I feel I will get clear results and therefore conduct a meaningful and knowledgeable investigation. I will be trying to determine whether ones height has any relevance to ones weight and then I will attempt to
Statistics Investigation Introduction I was given some data for 60 pupils in the school, with their height, foot length and gender. Firstly, I decided to compare this data by putting this data onto a graph and see if there is a correlation between height and foot length. I think that taller people will have bigger feet, which will be my hypotheses. Hypotheses My hypothesis is that taller people have bigger feet. Aim To find out if there is a correlation between height and
Passengers of the Titanic The relationship between the median ticket fare cost and whether the passenger survived or not. Question: I wonder if there is a difference in the median ticket fare cost (in the time’s British pound) between passengers that died and passengers that survived on the Titanic from a sample of the passenger data from the Titanic when it sank in 1912. The purpose of this question is to investigate whether passengers who paid more for their ticket had a better chance of surviving
have collected the data I will then organize the heights and weights of the girls and boys in a grouped frequency table. I will then use this table to find the mean, mode, median of the results of the heights and weights of these males and females. I will then construct a cumulative frequency graph to find and locate the median, lower quartile and upper quartile. This will then be used to draw a box plot for the heights and weights of male and females. This data will be used to help me to conclude
Analysis of Data Between Height and Weight in Girls and Boys In my first investigation, I will be analysing data between height and weight in girls and boys. I will also use this data to compare the results between boys and girls as well. I will use a variety of graphs to show this. PREDICTIONS I predict that as the heights increase, so will
There are 44 test scores from students and I am ask to analyze the data using different methods of graph. Talk about advantages and disadvantages of each graphs lastly describing the “Middle” and the “Spread” of the compiled data and how is it significant overall. There are many different types of graphs mathematician can use to compiles data to help them get a better understanding of everything by seeing it visually before start doing all the calculation and draw conclusion. The 4 types of graphs
better at estimating the length of a stick than year 7 pupils. Plan- In my investigation I plan to use secondary data gathered from both year 7 and year 10 pupils, which I will then do a random sample of which will be used to find the mean, median, mode, range as well as standard deviation which I will then put into groups and frequency tables to compare and from this I will hopefully be able to come to a conclusion. Aim- I am hoping to find if the statement that year 10 pupils are better
A Comparison of Newspaper Articles Introduction I have chosen the "Read All About It" option for my Maths Coursework. This involves comparing articles from newspapers and comparing them. I have chosen to use two newspapers for my investigation. I have chosen to compare articles from a Tabloid and a Broadsheet newspapers. The papers I have chosen are "The Mirror" and "The Guardian". I am predicting that the articles in the broadsheet newspapers would be more complex and often longer
Testing a Hypothesis about Male and Female Drivers My initial thoughts on the data are that it seems that more females are taking driving lessons than males as seen in the pie chart below. It would also seem that as the number of 1hour lessons increases the number of minor mistakes made decreases. Instructor B looks to be the most popular as he is chosen the most out of the four. I am going to state 3 hypotheses based on this data and am going to use my mathematical knowledge to support
Relationship between Height and Weight I am using the data from Mayfield high school as I am unable to use data from Nabwood School. This is because although the school has a database system, information regarding height and weight of year 10 and 11 students will not be accurate as it was taken when students came to the school in year 7, which was three or four years ago (if they are now in years 10 and 11). Therefore to try and update the database with the latest height and weight of year

The LQ is about the same as all the other medians, the median is higher than most of the other upper quartiles and the UQ is larger than all the others. The highest value is 125, this is the higher than all the others by at least 4. Evaluation Generally, my coursework went quite easily. I didn’t
greatly, when this happens the mean my not be the best measure of central tendency (Levine, et al., 2008). The median is another measure of central tendency that measures the half waypoint in a data set (Levine, et al., 2008). If the data set has an odd number, the median will be the middle ranked value (n+1 / 2) (Levine, et al., 2008). If the data set has an even number of values the median with be measured using the average of the two middle-ranked values (Levine, et al., 2008). The mode is the value
The medians are 100mm for length and 47mm for width. In both cases the box plots indicate a positive skew. To investigate the relationship of the length and width of the leaves as there are two [IMAGE] variables I shall draw a scatter
not really strong evidence to base the statement of fact that Brunettes are more intelligent as they have higher IQ's than the Blondes. The Box and Whisker Diagram for the Blonde Females IQ has a larger Lower Quartile, a smaller Median area, and a larger Upper Quartile than the Brunette Females IQ. The spacing of the sections in these diagrams shows to me that due to the Blonde Females having a smaller Lower Quartile IQ space there are less people in this section
Project 1 The winter sport of skiing and snowboarding has a huge market base in South Lake Tahoe, California. Tahoe locals and tourists from all over the world come to South Lake Tahoe to ski/snowboard at their ski resorts. Visitors range from toddlers to elders, which makes the ski resorts very family friendly. Heavenly and Sierra at Tahoe are the main ski resorts in South Lake Tahoe, and they are always looking for ways to make their resorts better. Both Sierra at Tahoe and Heavenly are interested
Statistics are necessary for scientific research because they allow the researchers to analyze empirical data needed to interpret the findings and draw conclusions based on the results of the research. According to Portney and Watkins (2009), all studies require a description of subjects and responses that are obtained through measuring central tendency, so all studies use descriptive statistics to present an appropriate use of statistical tests and the validity of data interpretation. Although descriptive
Measures of central tendency which include, the mean, median and mode, attempt to provide the centre point of the data set as wells as represent it with all with one value. Whereas measures of variability (range, interquartile range, variance and standard deviation) attempt to show the spread or difference in a data set. The mean, also known as the average, is the sum of all the values in a set of data divided by the number of values in said set. For example a class of 10 students were administered
Investigating the Relationship Between Foot Size and Height I predict that the taller the pupil is, the bigger their foot size will be. Plan ==== I’ve been given 60 pieces of data from pupils, about their height and foot size. I will be using a piece of software called Fathom where I will place this information into a scatter graph, to see whether or not my hypothesis is correct. Fathom will produce a line of best fit on my graph and tell me what my r-value is. The r-value shows
