It is often used in explanatory data analysis. This type of graph is used to show the shape of the distribution, its central value, and its variability. In a box and whisper plot, the ends of the box are the upper and lower quartiles, so the box spans the interquartile range.

To find the a and b (for the equation of regression line, y=a+bx) and the r (correlation),
To find the n (amount of data), standard deviation of x and y, mean x and mean y,

y = A + Bx

A is y-intercept while B is the gradient / slope. This equation is similar to the equation y = mx + b. X is the explanatory variable and Y is the dependent variable.

Example 2: ๐Ÿ’‰ Medicine ๐Ÿ’Š
