How to Draw Best-Fitting Lines
Description
A detailed tutorial on how to draw best-fitting lines. Step by step tutorial including several examples on how to draw best-fitting lines for reference.
Overview
Best-fitting lines are lines that are drawn on a graph or on scatter plots. However, a best-fitting line is different than a normal line found on a graph. A normal graph simply requires you to connect the dots. A best fitting line focuses not on what dots to connect, but how to connect them. The line will curve or go in different directions, not just straight to the other line, depending on the relationship of the two dots to each other. Best-fitting lines typically require more information than simply the graph, you must explore the equation and each point to find the true relationships, and from that you can find the best-fitting line.

How to Make a Stem-and-Leaf Plot
Description
A detailed tutorial on how to make a stem-and-leaf plot. Step by step tutorial including several examples of how to make a stem-and-leaf plot for reference.
Overview
A stem-and-leaf plot is named for it’s resemblance to a tree branch. The bar down the middle is the branch, and the numbers on either side are the leaves on the branch. Like box-and-whisker plots, stem-and-leaf plots are used to organize statistical data. There should be one number on the left side of the bar, and that number should be the number in the ten’s place. If it is only a one digit number, that number should be zero. If it is a three digit number, then put two numbers on the left. Then you have the bar. On the right side of the bar, are all the numbers that are found in the hundred’s place, put once again in order of smallest to largest. They will all appear in the row with with the matching number in the ten’s place.

How to Make a Box-and-Whisker Plot
Description
A detailed tutorial on how to make a box-and-whisker plot. Step by step tutorial including several examples of how to make a box-and-whisker plot for reference.
Overview
A box-and-whisker plot is named for it’s resemblance to a cat’s face – the box is the face of the cat, and the lines extending out from either side are known as whiskers. Sometimes box-and-whisker plots are simply called box plots. They are used to graph sets of numbers according to five values: the highest value, known as the maximum, the second highest value, known as the upper quartile, the median, or the middle, the second lowest value, known as the lower quartile, and the lowest value, known as the minimum. The box centers around the median and the whiskers extend out to the other numbers.

Definition of a Cornu Spiral
Description
A detailed tutorial on Cornu spirals. Step by step tutorial including a visual example of a Cornu spiral for reference.
Overview
The Cornu spiral is also known as a Euler spiral and clothoid. It is generated as a straight line that branches out, and then turns up on one end and down on the other, both spiraling into tight curls. It is formed by a parametric plot of S(t) against C(t). They are very closely linking to Fresnal integrals and have been sometimes thought of as a solution.
