Final answer:
A flow diagram is the most helpful resource for explaining the machine learning process to a layperson because it provides an easy-to-understand visual representation of the steps involved without including overly technical details.
Step-by-step explanation:
To explain the machine learning process to a layperson, the most helpful resource would be A flow diagram of the overall steps in the process. This would visually demonstrate the sequence of events in machine learning, from data collection to model training and evaluation. While a scatter plot showing the relationship between two variables and the step-by-step deconstruction of formulas used by machine learning algorithms can provide detailed insights, they may be too complex for someone unfamiliar with the subject matter. In contrast, a flow diagram is an accessible way to illustrate the data visualization and patterning that occurs within machine learning without overwhelming a layperson with technical details.
