When making a box plot, the easiest place to start is the line that is inside the box. This line is the median of the dataset. Half of the data falls above that line and half falls below it.
We can find the median of a dataset by using NumPy’s
import numpy as np dataset = [4, 8, 15, 16, 23] dataset_median = np.median(dataset) # dataset_median stores the value 15
Over the next few exercises, we’re going to build a boxplot by hand, using an example dataset.
We’ve imported a dataset named
dataset. Create a variable named
dataset_median. Use NumPy’s
median() function to set
dataset_median equal to the median of the dataset.
After running the code, you should see the median print to the terminal. Using that value, draw the a line in the browser at the correct location.
You can refresh the browser component if you want to re-draw the line.
