Data's Basic Story Telling Tools: Bar Graph and Histogram Graph

Most of the problems that data scientists must solve involve how much or how many? (regression), which category? (classification), what’s wrong with the data? (anomaly detection), and would a user prefer this? (recommender systems). The first step to solving any of these problems is to determine what type of data is at hand. So, if I am asked to compare the number of companies with their associated revenues, which graph would I use?

First Impression

When I first read about the data science course offered by Flatiron school, I immediately thought about the research process that takes place in universities: devising an experiment, collecting data, analyzing the data, organizing it, drawing a conclusion from it, and presenting it. I had experience in the process, so I knew I would enjoy it. Although, I will admit that I thought it only applied in this field alone.
