Concluding coursework

How I supported my evidence to support my hypotheses

In this project I had 2 hypotheses that I had to try and prove. The first was boys are taller than girls and the second hypothesis was the taller you are the bigger feet you have. I have proved both these hypotheses are true. My hypotheses are supported by graphs and discussions to show what the graphs are about and how they support my hypothesis. I have interpreted my findings so it is easily seen what the graph is trying to say and how it effects my hypothesis, if it supports my hypothesis or not. The interpretations go into more detail about what the graph is trying to tell you.

Improvements I could make on my coursework

I could of improved on my project by having a bigger sample, which would of made even more accurate results in the graphs and help support my hypotheses even more accurately. Other improvement I could of made was to investigate more hypotheses which would of meant more calculations which would show I no how to do more advance mathematics.

Weaknesses of my coursework

The weaknesses in my coursework were the limitations that I had. Like the sample size had to be between 30 and 40 people which is not a very big sample size with might of made my results a little inaccurate instead if I had a bigger sample size I could have been a lot more accurate. Another limitation was the fact I only could have 2 hypotheses, if I used more than 2 hypotheses I could of proved a lot more about the selected population. Time was a big limitation in this project that meant we had to have a small sample size so we could get results from it quickly. If we had more time we could have had a bigger sample size and made the project more accurate. The sample used was only from one year in one school, if we used a different year in a different school the results could have been different this could If we looked at other students in other years or in different areas that could of helped to support the hypotheses more strongly.

There is one way that I could have been more accurate with my results and that would be to have a bigger sample size. This would make my results more accurate as it would be taking results of a lot more people which means its more accurate in saying what it would be like for a large sum of people but if you have a small sample size the results may not reflect the large sum of people which makes the sample inaccurate. I think the population having information about kids from other years and schools to make it a more general sample to be more accurate. The way the sample could have been better is if it was bigger to gain more accurate results

    It also shows the median of the data. Box and whiskers diagram can be easily compared with each other to see which year group have a stronger (higher) percentage of attendance during the academic year. 2.3 Histograms I am going to use histograms instead of bar charts is because the data I'm using is a continuous grouped data.

    The mean percentage error is worked out by dividing the total percentage error by how many pieces of data there are. So, for the mean of the year 9 line errors, the calculation would be 143.48/27 which equals 5.31%. This is quite a low percentage of error which means that the year 9's were quite good at estimating the line.

  2. Estimating the length of a line and the size of an angle.

    This is because the length of a line can be estimated accurately because most people use rulers frequently to measure fundamental things and so they will be better at estimating the length of a line than estimating the size of an angle which are used less frequently and is very difficult because the angles can be tricky at times.

    To check that I am correct with my correlations, I have calculated some things on Excel. First I calculated the Product Moment Correlation Coefficient (PMCC). When I was researching this, I found that PMCC could be found in two ways.

    Now I will calculate my Spearmans. =CORREL(L12:L61,M12:M61) My Spearmans Rank for my sample was 0.88. This again shows that my correlation is positive and very strong as 0.88 is very close to 1 on the scale. These calculations both mean that my data is really close together, and that the
