Designing data collection methods for computational analysis

For results to be suitable for computational analysis it is usual to design responses so they can be easily coded. Enter a code (numeric/alpha-numeric) entry is simplified as is analysis and interpretation.
Simplest form of coding is binary for yes/no questions. Yes represented by 1 and No represented by 0. Hence a series of eight questions may result in 10110010 – four yeses and four nos.
