Are findings from the sample generalizable?

You just saw how convenience sampling—collecting data using the easiest method—can result in samples that aren't representative of the population. Equivalently, this means findings from the sample are not generalizable to the population. Visualizing the distributions of the population and the sample can help determine whether or not the sample is representative of the population.

The Spotify dataset contains an acousticness column, which is a confidence measure from zero to one of whether the track was made with instruments that aren't plugged in. You'll compare the acousticness distribution of the total population of songs with a sample of those songs.

spotify_population and spotify_mysterious_sample are available; pandas as pd, matplotlib.pyplot as plt, and numpy as np are loaded.
