Problem: Does our class have the perfect body proportion as per Vitruvian man?
My two variables are Height and Armspan
Plan
Q-Do we have the perfect body proportions in this class?
P-Our participants will be the population of Mr Rees year 11 Math class.
V- The explanatory variable is height in meters and the response variable is armspan in meters.
R- Our relationship is to measure the length of our armspan and our height correctly so we get the same measurement.
What and Who is Vitruvian man?
The Vitruvian Man, a late 15th-century drawing, is a prime example of such work. Intended to explore the idea of proportion, the piece is part work of art and part mathematical diagram, conveying the Old Master's belief that “everything connects to everything else.”
Manufacture of a Sawhorse using Hand tools for my Building Construction Industry Trades Organization qualification.
In term 1 2021 I learnt how to use hand tools to manufacture a Saw Horse to a specific size from a set of drawings. This took about 6 weeks (24 hrs) I will explain how to make a sawhorse in this blog post
Here is my finished project.
This project was made by using hand tools only. No powered tools were used apart from a battery-powered drill to drill the holes for the screws.
I enjoyed drilling the holes the most because it was interesting trying to get the screws into the holes and not drilling too deep into the wood.
I found marking out the holes for the legs the most difficult part because I was struggling to make them the right size. I overcame this by getting a friend to show me how to do it on his work and then I tried it and it worked.
To make a sawhorse I carried out the following processes.
For this project we had to use a saw, marking gauge, pencil, a sliding bevel, woodwork square, clamps, ruler, plane, vice, chisel, and a hammer.
First, we had to get our pieces of wood and right top and bottom on it and our names. Next, we had to mark out all of our lines on all of our wood including the 15° angle. Then we had to mark outlines on each side of the wood for the legs. Once we marked them out we had to cut little lines in between those lines so that we could use the chisel and hammer to make the holes for the legs. When we finished chiseling out the holes we had to keep a piece of long wood and cut it into four pieces for our legs. Then we had to mark out some lines on the legs to start plaining it so that the legs would fit into the holes.
For the legs to fit we had to plain the bottom part of the leg and then plain the side for it to fit. Once we plained the legs, we had to put them in place and drill them in. When the legs have been drilled in place, we had to cut a piece of wood to go on the bottom of the wood and we drilled them in. At the end of this project, we had to put in the side plates, we drilled the side plates onto the wood and then the project was finished.

Critical Literacy:
Task: NRL
Writing: In the NRL they have made a rule that if you make a high tackle you get sin-binned or red-carded. This rule is stupid because most high tackles are on accident.
It is important in the field of statistics because they model many real-world data like test results and performance reviews.
"Bell curve" refers to the bell shape that is created when a line is plotted using the data points for an item that meets the criteria of normal distribution.
Look at the symmetrical shape of a bell curve. The center should be where the largest portion of scores would fall.
What are the different types of graphs and their uses?
Bar Graph: A Bar Graph is used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar
graphs are best when the changes are larger.
Pie graph: A pie graph can be used to show percentages. A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice is proportional to the quantity it represents. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.
Donut Graph: A donut graph is used to show the proportions of data. The donut graph was created using a count of features. Displaying values or percentages in data labels is very useful in a doughnut chart, but if you want to compare the data points side by side, you should use a stacked column or stacked bar chart instead. Consider using a doughnut chart when: You have one or more data series that you want to plot.
Line chart: A line chart is a graphical representation of an asset's historical price action that connects a series of data points with a continuous line. This is the most basic type of chart used in finance, and it typically only depicts a security's closing prices over time. Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.
Scatter Graph: A scatter plot’s primary uses are to observe and show relationships between two variables. The dots in a scatter plot represent the values of the data that you have received.
