Question

match each word to its definition.
observations a scientist collects and records to use for analysis
a. hypothesis
a proposed explanation that can be tested through scientific investigation
b. data
the variable that a scientist measures or collects data about during an investigation
c. dependent variable

Explanation:

1. For the first phrase "observations a scientist collects and records to use for analysis", the term that matches is "data" (option b) because data refers to the information (observations) gathered for analysis.
2. For "a proposed explanation that can be tested through scientific investigation", this is the definition of a "hypothesis" (option a) as a hypothesis is a testable explanation.
3. For "the variable that a scientist measures or collects data about during an investigation", this is the "dependent variable" (option c) since the dependent variable is what is being measured in an experiment.

Answer:

• "observations a scientist collects and records to use for analysis" matches with b. data
• "a proposed explanation that can be tested through scientific investigation" matches with a. hypothesis
• "the variable that a scientist measures or collects data about during an investigation" matches with c. dependent variable
