But Baby, my Feets too Big!!!!!September 22, 2009
Those Hippie Statisticians at The Australian Bureau of Statistics (ABS) are Navel Gazing Again!!!! . Here are the statistics for the height of students belly buttons above the ground for Year 4 – 12 students. ABS #mce_temp_url#
Before we do any maths with students height mathspigs, be warned. Students can be teased or embarrassed by their height. Mathspig has always argued that a lampost is tall but does not have much of a personality. And a bee is very small but you’d be crazy to tease one. Nevertheless we will use celebrity heights and average student heights instead.
Here we go!!!!!
Look at the data. It is useless. THIS IS THE POINT. You have to make sense of data not just sprout numbers. Foot sizes actually shrink!!!! There is insufficient information. The ABS random sample size used was too small. So baby your feet might be too big… but we can’t tell from this data.
The Vitruvian Man is a world-renowned drawing created by Leonardo da Vinci around the year 1487. This sketch supposedly represents the perfect proportions in man. Measure Height and Belly Button Height of Vertruvian man. Divide his Belly Button Height by his full height.
We will call this the DIVINE FRACTION.
How do Aussie Students compare? You have the data needed to calculate the DIVINE FRACTION for each year level.
Q3: How do the average heights of our students compare to students in other countries?
If we could took a very, very large number of student heights they would produce the graph below. It is a NORMAL DISTRIBUTION or A BELL CURVE. The curve below is for young adults in the USA. We do not know the actual number of students for each height.
ADVANCED MATHSPIGS; You will find more data, a cute bar graph using students and some interesting bimodal graphs (combining the Bell Curves for Female and Male heights) @#mce_temp_url#
How do Aussies compare? See the graphs below. We do not know how many students are involved. We can only say our average Year 12 student is taller than the majority of their students!!! Ha! HA! If, that is, the data is reliable and the foot sizes suggest maybe NOT.
Q 4: How does the average height of Aussie students for each Year level compare with celebrities?
