Analysis of data in Corfe Castle

Following on from my previous revision guide for field work.

Analysing the IPSOS MORI data
  • To analyse, we undertook the chi squared test of significance
  • Measure the relationship between age and satisfaction with life
  • We used the degrees of freedom, and decided to accept the alternate hypothesis and reject the null hypothesis
What is Chi Squared?
  • You will not be asked to explain chi-squared. It is a statistical test like Spearman's rank (which you DO need to know!)
Null hypothesis
  • In statistics, you assume there is no relation until one is proven.
  • No relation = null hypothesis
  • We proved (using chi squared) that there WAS a relation, hence we reject the null hypothesis,

Coursera Week 1: Sustainable Urban Transformation

This week looked at what a sustainable city actually is. I watched a lecture by Kes McCormick, who talked about the processes behind sustainable urban transformation. There was also a talk by James Evans, a professor at Manchester University, who talked about how cities learn to be sustainable. Dr. Jennifer Lenhart talked about the importance and characteristics on urban climate governance. A video by The Economist on efficient energy use in cities A video by WWF on housing adaptation The Urban Green Part 1 The reading this week was on Sustainable Urban Transformation and the Green Urban Economy Click here to access it The key points from this week were: Kes McCormick The 21st Century has been called the 'Urban Century' by UN-Habitat. This is because more people now live in cities that rural areas, and because of the strategic importance of cities in sustainable global development. Cities are not just a source of environmental problems, they also provide oppo

AQA A level geography notes

https://drive.google.com/drive/folders/1YpMgUsfx6DE4ndGuoYbmFegoeTq29GO4 This contains every case study and set of notes for: Changing Places Coastal Systems Contemporary Urban Environments Global Systems and Governance Water and Carbon Cycles Natural Hazard* *Natural Hazards will be added once we finish the current topics in time for mocks. I will add to them again before the real exams I felt the human half of Contemporary Urban Environments was lacking a bit, so I've added to it using different textbooks. The Changing Places section has also been developed, and the case study covers the data sources we were meant to learn about. Coastal Systems notes and case studies are very much the same, so don't feel the need to print it off again for the sake of it

How can Quebec and the UK save electricity?

Reducing energy consumption is imperative in the work to mitigate climate change; however, it has economic benefits as well: less money need be spent by the government in outsourcing energy supply to meet exceeding demand. Overconsumption and wastage of energy is predominantly a high income country (HIC) problem, but the technology developed to save wasted energy can be used throughout the globe to achieve the goal of sustainable development. In the UK, the largest consumer of energy is the transport industry. Perhaps the biggest source of wasted energy is found in the braking systems of vehicles. Typically, braking puts pressure on the wheels, and kinetic energy is wasted as heat formed by friction; regenerative braking changes this. A pilot study in Pennsylvania managed to recover up to 20% of the energy used in braking trains at a station. The saved electricity was used to start the next train in the station in its departure. A simple way to reduce energy consumption in the public
