Definition
Sum, average, count, minimum, and maximum can summarise visible numerical records.
Important terms
- Totals row
- Sum, average, count, minimum, and maximum can summarise visible numerical records.
- Totals
- Sum, average, count, minimum, and maximum can summarise visible numerical records.
Overview
Learn the concept through terminology and working:
Terminology and Concept
Terminology: use Totals row, Totals precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
Examples Sum, average, count, minimum, and maximum can summarise visible numerical records.
Working and Application
Working method: first identify the input or starting state for totals row; then apply the rule or process in a clear order; finally inspect the output, test an edge case, and explain any limitation.
Examples Example: apply totals row to a small school, home, or software problem and trace the result.
CONCEPT — What it means
Sum, average, count, minimum, and maximum can summarise visible numerical records.
TERMINOLOGY — Words to use
Terminology: use Totals row, Totals precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
WORKING — How it operates
Working method: first identify the input or starting state for totals row; then apply the rule or process in a clear order; finally inspect the output, test an edge case, and explain any limitation.
EXAMPLE — Apply it
Example: apply totals row to a small school, home, or software problem and trace the result.
In simple words
