Data Lab Elementary: Conjecture and justification challenge

Data Lab Elementary focus: data representation, variation, and comparison. A conjecture fits familiar cases but its domain is not yet justified.

What representation and justification make a Grade 9 claim about data representation, variation, and comparison valid within its stated domain?

Model

Representations, assumptions, and quantities

Test 3 cases using a visual model, table or graph, and symbolic rule. Record assumptions and a boundary value.

Represent: Data Lab Elementary visual model, table or graph, symbolic rule
Justify: Connect equivalent representations and justify each inference about Use Data Lab Elementary to investigate data representation, variation, and comparison and produce a defensible data & analysis explanation, design, interpretation, or decision.
Counterexample: A universal claim must survive a boundary case or be revised to state its domain.
Assumptions: Name the domain, parameter constraints, and whether a computed case establishes or merely illustrates the claim.
