The relationship between two sets of Key Stage 2 results, (Maths and Science). This is hard to judge, as some pupil may be good at maths but not at science, or vice versa. But I think more pupils will gain maths level than science. tcwqX Visit coursework ec in ec fo ec for ec more project ec Do ec not ec redistribute tcwqX 3. The relationship between IQ and Key Stage 2 (English) results in year 7. I expect maths to be high with pupils with high IQ's in year 7. This work from www.coursework.infoThis data will be found from an electronic database, which has been put in by Mayfield High School, (recently). So the results/data is accurate. I know this data is reliable because it will be checked thoroughly and be made sure it is correct and seem sensible. Many sample sizes will be taken, such as; simple random sampling and stratified sampling. I will be doing a simple random sample because, it will be organised, saves time and it won't be bias. Also the bigger the sample sizes the more reliable, and I will be doing a sample of 50. It will be fair because it is simply random and I will not just pick out the best ones, so there would be no anomaly's. This data will be used to compare the correlation between height and weight of males and females of year 7. The correlation between two sets of Key Stage 2 results (Maths and English). The correlation between IQ and Key Stage 2 results (English). Lots of mathematical diagrams will be used such as, box plots, scatter graphs, cumulative frequency curve, histograms and bar charts. These will be used because the data will be shown more clearly. I expect anomalous results such as a short fat boy or a tall fat female. The results can be too much, as I am looking at year 7 there will be enough information. 1rVLbmpjS Visit coursework gd in gd fo gd for gd more cours gd Do gd not gd redistribute 1rVLbmpjS The following calculations will be performed during this investigation;codb dbr sedbdbw ordb dbk indb fodb db.· Sampling - When one collects data one almost always has to take a sample from the population. One uses the sample to make judgments about the whole population, so it is important that the sample is chosen in a way that makes it representive of the population. zain, please do not redistribute this cours.

Anybody found doing so will be permanently banned.· Mean, Median and Mode - are all ways of describing a typical value. They are sometimes called measures of control tendency. Mean; is the average of the data. Medium; is the middle value of the data. Mode; is the most common data. This hypothesis from www.coursework.info· Standard deviation - While mean absolute deviation is a perfectly good measure of spread, it is not actually very widely used. Instead a different procedure is followed in which you square the deviations, rather than their absolute values, leading to the measure called standard deviation.cogc gcr segcgcw orgc gck ingc fogc gc.These calculations will help prove my investigation, and be useful because they will analyse the statistics data more quickly, easier and efficiently.cogf gfr segfgfw orgf gfk ingf fogf gf.I will use diagrams such as;coff ffr seffffw orff ffk inff foff ff;· Scatter graphs - The line of best fit can be used to estimate an unknown value.

Austen refuted zain's rationalisation theory.· Box plots & Box and whiskers - The box is used to represent the central 50% of the data and the whiskers extend from the box to the smallest and largest values give an indication of the overall spread of the data. hUY36lT8m Visit coursework ad in ad fo ad for ad more paper ad Do ad not ad redistribute hUY36lT8m · Stem and leaf - They can be used to find quantiles, in particular the quartiles.coff ffr seffffw orff ffk inff foff ff.Others; Durkheim obfuscated zain's structuralism idea.· Quartiles - Of an ordered set of data are such that
