Maths GCSE Statistics Coursework

... Introduction I have been asked to compare 173 year 7 pupils and 178-year 11 pupils who were asked to estimate the length of a bamboo stick to the nearest centimetre, which was held horizontally not vertical. I am going to investigate the two different age groups to see who had the more constant guesses from the secondary data, I have been given. The actual length of the bamboo stick is 1.58 metres. As 351pieces of data would be too big to sample, I am going to random sample 50 pieces of the data for each year. Not to be biased I am going to stratify my data to keep the boys and girls in proportion. Hypothesis 1 I predict that the ability to accurately guess the length of the bamboo stick will increase by age group; this implies to me that the overall average year 11 guess will be close to the actual

User Reviews of this Essay

What our users think of this essay:

"Fair at best. The write-up includes some explanation of the basic principles concerned here, but makes no effort to expand on this base-level work. It's good to see some discussion of sampling techniques, but the choice of technique is not justified. The majority of the report consists of data tables, which are fine but don't add much to the report. I would have expected to see some analysis of the spread of the data (e.g. using standard deviation) as well as calculation of the mean (on its own this is *very* basic), while the conclusion should be accompanied by a discussion of how strongly the results support the hypotheses (rather than a simple yes/no picture).
