Statistics Experiment Essay
For my maths coursework I will be conducting an investigation into statistics. I had a choice for this coursework of both statistics on year 10 to 11 school children, and facts about them and also their likes in terms of sport and subjects at school. I chose not to do this project on that information; instead I chose data on 100 different cars, the reason for this is that I like cars more and may perhaps pursue it as a career. I did not want to do a project on data that I have no interest in.
The 100 different cars have data under the following headings, Car number in order from 1 to 100, the make of the car, the price when new of the car, the current second hand price, …show more content…
My investigation will be:
The frequency of mileage in my sample, if there is a relationship between the second hand price and age of a car, and finally if there is relationship between the age and percentage loss of a car.
I will be taking a sample of 20 cars; I will take every 5th car in the database. I will show the data in terms of tables, a tally chart, and by way of bar, and scatter graphs with a line of best fit if applicable.
To improve my investigation I will take a sample of 5 cars, which will not be included in my final investigation, but this 5 car sample is to test my investigation techniques, and to allow me to foresee and problems and practise in investigating statistics.
I will not be able to take all 100 cars and will have to do my investigations on different samples of the survey, I hope to take 1/5 of the cars, and I will do my investigations on 20 cars. I

This procedure is useful for studies in which three or more groups create rankings of items. The resulting statistic represents the level of agreement among the groups in ranking the items. For example, you could create a list of ten competencies required of an effective minister of education. You then send this list to a sample of pastors, a sample of ministers…

A Experiment On The Group
1796 Words  8 PagesIn this experiment, the participants were tested on both conditions, which are congruent trials and also the incongruent trials. I used within subject experimental design to find the pvalue under the assumption that the difference between the congruent and incongruent conditions are only happening due to random chance. In the simulation, I put all the data of the incongruent reading time (seconds) in the group A and all the data of the congruent reading time (seconds) in the group B. Then, I run…

One technique used was Doebner reaction and the other technique used was ClaisenSchmidt reaction. Therefore the aim of this experiment is to synthesize trans pmethoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol…
