Introduction

Maths statistics coursework

 My coursework will involve me investigating the relationships and correlations between the data in the Mayfield high spreadsheet. I will be analysing the data and portraying them in different statistical forms. I have decided to look at the height, weight, gender and age. By looking at these I can make a hypothesis and predict outcomes like as follows:

My first Hypothesis:

I predict that genders affect your weight e.g. boys are heavier than girls. I shall do this by using averages and means for boys and for girls and then comparing the two set to see. I think that boys will be heavier than girls of the same age, this is because of many different reasons, like body mass is higher for boys than girls. In my investigation I may find outliers that may offset my results.

The year 8 mean shows that the girls are heavier than the boys at this point. This means that the girls are at their peak of their growth spurt compared to the boys. The range shows that girls at this point have a more varied weight than the boys.

Conclusion

I conclude that the my hypothesis was correct at the end of the investigation but as my results shows the hypothesis isn’t correct whilst the pupils were in the years 7,8,9,10 this would be because of the physical difference between when sexes have their growth spurts. I believe that boys over the year of 11 will be heavier on average than girls excluding any outliers. This was downloaded from courswork.info so if you haven’t read this and understood it then you’re cheating yourself and will be found out During the years 7,8,9,10 the girls have a larger range as there growth is staggered across these years but at years 11 the girls have stopped growing and the boys are growing at their peak and so their range is bigger.

    Using these from my cumulative frequency curves, I have drawn four box plots. Outliers are not present in every box plot drawn, except one where there is an extreme value which deviates significantly from the rest of the sample. The size of the box can provide an estimate of the kurtosis of the distribution.

The data in the cumulative frequency column will be plotted onto a cumulative frequency graph, to show the spread of data and then the median, upper quartile and lower quartile will be plotted in a box plot to show the inter-quartile range (the upper quartile take away the lower quartile)

    The class widths are therefore 6, 5 and 2. The area of a histogram represents the frequency. The areas of our bars should therefore be 6, 15 and 4. This information can be marked on the grid. A frequency polygon is an easy way of comparing two sets of data frequencies as they can be drawn on the same graph.
