Mayfield High School

Introduction

I have decided to investigate the truth behind the theory that “Blonde haired, blue eyed people are better than others” brought out by Adolf Hitler. I will be trying to see if blonde haired, blue eyed people are generally better than people with other types of hair and eye colour.

The concept ofaryanization” is a Nazi concept based on Hitler's ideology that the Aryan race is a master race, cleverer, more beautiful (in terms of females) and more muscular (in terms of males) than other races.

I have decided to carry out an investigation to see if this true by looking at secondary school pupils. Mayfield High school is fictitious secondary school with records based on a real school. Using the student database, I will try to see if aryanization theory of the Nazis had any basis at all.

Planning

Mayfield High school has 1,183 students, of which 179 are blonde haired and blue eyed. There are 124 of these students in Key stage 3 and 55 students in Key Stage 4.

I will be starting off with the students in Key Stage 3. This means I will be doing my research on students in Year 7 to Year 9. Secondly, I will research into the students of Key Stage 4, the students in Year 10 and Year 11.

To do a proper investigation, I will have to take samples from each class. I will use the stratified sampling method. I will choose a 10% average from each group. Due to the fact that there will be a different number of students in each year group, the average number of students chosen from one year group will be different from the number of students chosen from another year group.

 22 (2sf)

The standard deviation of the IQ of the students in Key Stage 4 is 22. From this I can gather that the dispersion across both sides of the mean (99.97) is quite widespread. This shows that generally the Key Stage 4 students are not so intelligent. However this means that the lowest average IQ is 77.97 and the highest average is 121.97.

Because the standard deviation is 22 and the mean is 99.97, the standard deviation shows that the data is widespread across the mean, which in turn shows that there are extreme values. The presence of extreme values proves that some students have a very high intelligence quotient while others may not have an IQ that high. This would in turn; mean that the group as a whole does not have a very high intelligence quotient.

I will now be measuring the dispersion of the IQ of the blonde haired and blue eyed students in Key Stage 3; from the mean IQ of Key Stage 3.

Blonde-haired, blue-eyed students (KS3)

I will again be using the equation

    ∑X2

     n

The mean is 101.56.

Conclusion

image02.png


The two box plots above back up my conclusions that I derived from the scatter graphs that I used to show the IQ of the two different samples for Year 7.

Year 8 (both samples)image03.png


Again, these whisker box plots back up the conclusions that I derived from the scatter graphs that I used to show the IQ of the two different samples of Year 8.

Year 9 (both samples)


image04.png

Just as before, the whisker box plots above, back up the conclusions that I derived from the scatter graphs that I used to show the IQ of the two different samples of Year 9.

The box plots have all backed my conclusions that I gathered from the scatter graphs that were drawn using the IQ of both the blonde-haired, blue-eyed students and the non blonde-haired, blue-eyed students in all the year groups.

When I first started, I was investigating the truth behind the theory that “Blonde haired, blue eyed people are better than others” brought out by Adolf Hitler. I will be trying to see if blonde haired, blue eyed people are generally better than people with other types of hair and eye colour. I wanted to see which statement was truer, Adolf Hitler’s or the general stereotypical theory that all blonde-haired, blue-eyed people are “all play, no work” in other words, air-heads.

From the various calculations that I carried out, and the conclusions that I have gathered from the different types of graphs that were drawn, I can say that generally blonde-haired, blue-eyed students are more intelligent than their student counterparts with different phenotypes. Therefore, it seems that Adolf Hitler was not talking just racist nonsense; his theory does seem to have some truth behind it.

I believe I have gained substantial evidence, and have shown with it, that blonde-haired, blue-eyed students in each year have very similar IQ. Their abilities do not vary a lot, and all of them are generally similar in their capabilities.
