What are two key components in creating data analysis tools from scratch? (Choose two.)
- data sets
- program length
Explanation: Modeling and coding are the two key components in the process of creating data analysis tools from scratch. Modeling consists of deciding what to do with the data to achieve the desired results and conclusions. A well-developed model can be used to handle multiple types of data sets. The code is the program that implements the model and processes the data according to the model already developed. The length and performance are factors and features of a program.
