What’s the answer
As pizza consumption increases so does a person's anger level: Correlational Research
A group that breathed pure oxygen had better test performance than a group that breathed normal air: Causal Research
People who eat breakfast most days tend to have a higher GPA: Correlational Research
A group that consumed more caffeine showed less ability to focus than a group that consumed no caffeine: Causal Research
As exercise rate increases, a person's memory increases: Correlational Research
- The claim "As pizza consumption increases so does a person's anger level" can be categorized as correlational research. This type of research aims to identify relationships or associations between variables but does not determine the cause-effect relationship.
- The claim "A group that breathed pure oxygen had better test performance than a group that breathed normal air" can be categorized as causal research. This type of research aims to establish a cause-effect relationship between variables by manipulating one variable and assessing the resulting effect.
- The claim "People who eat breakfast most days tend to have a higher GPA" can be categorized as correlational research. It identifies a relationship between eating breakfast and GPA but does not establish a causal link.
- The claim "A group that consumed more caffeine showed less ability to focus than a group that consumed no caffeine" can also be classified as correlational research. It identifies a relationship between caffeine consumption and focus but does not establish causality.
- The claim "As exercise rate increases, a person's memory increases" can be categorized as correlational research. It identifies a positive relationship between exercise rate and memory performance but does not establish causality.
Therefore:
Claim 1: Correlational Research
Claim 2: Causal Research
Claim 3: Correlational Research
Claim 4: Correlational Research
Claim 5: Correlational Research
