Box and Whisker plot
Box and Whisker plot
Box and whisker graphs can be used to display the mean, median (regular, lower and upper), and mode all at once. Here are the steps to create one,
Write the range of data in a number line
Place dots at the start and end of the range
Draw dot with vertical line for the median, then calculate the upper and lower median
Draw two dots and vertical lines for the upper and lower median to create quarters
Draw horizontal lines to connect the median line to the upper and lower medium to create a box
Draw to ‘whiskers’ (lines) from the ranges dots to the median dots to display quarters within the data

Wire Length and Weight Scatter plot
Wire Length and Weight Scatter plot
Today we measured 10 different pieces of wire and weighed them. With that we created a table to display our data and then put it into a scatter plot graph. After that, we had to figure out how much a 300 cm wire would weigh. We had to do the same but for a theoretical 500g wire and find the length. I used proportions to solve this instead of making a very large table.

Area and Length Relationship
Area and Length Relationship
Something quite interesting I learned today was that a rectangle can have many different areas even with the same perimeter. The way to get the largest area is to create a square using your given perimeter. The highest point in the scatter plot is where the largest area is, and the length is half of the perimeter. For example the middle point is at 14 and 13 because that is half of 27. The table below display this along with the largest area.
