Accountant → Data Scientist | Writing about the business of data science. Helping you create impact with data and machine learning.
If you want to run successful data science projects, you can rely on a framework you learned in grade school.
It's called The Scientific Method.
Here are the steps, and how they apply to data science for business.
#1: Observation / question
State the problem.
Losing customers?
Designing a new product?
Spending too much money?
#2: Research topic
To research a potential data science project, you need to do two things.
Gather and investigate data
Interview relevant stakeholders
#3: Hypothesis
Now you're becoming a subject matter expert.
Frame your upcoming work with a best guess at the answer.
#4: Experimentation
There are five pieces to a holistic data science experiment:
Independent variables (features)
Feature engineering
Dependent variables (outcome or target variable)
Model selection
Model parameters
#5: Analyze results
The most important part of your experiment?
Model evaluation.
#6: Report conclusions
Wrap your work in a deliverable that your stakeholders can understand and consume.
#7: Iterate
Armed with new information, cycle through the process until you reach a conclusion.
