Investigations
Answer: This type of investigation uses observations to describe what is occurring without intervention.
Question: What is a descriptive investigation?
Answer: A detailed observation of a single event, often written as a story.
Question: What is a case study?
Answer: Engineering designs are evaluated to determine these two things.
Question: What are the design's strengths and weaknesses?
Answer: Reliability means the experiment's data can be __________.
Question: What is reproduced?
Answer: These studies help engineers closely examine products in specific scenarios.
Question: What are case studies?
Answer: These investigations attempt to determine relationships between variables through intervention and manipulation.
Question: What are experimental investigations?
Answer: This study observes subjects at one point in time within specific criteria.
Question: What is a cross-sectional study?
Answer: This type of analysis asks if a product solves the problem and works consistently.
Question: What is functional analysis?
Answer: This is the process of selecting subjects to participate in a study.
Question: What is sampling?
Answer: These studies often use surveys to gather information about consumers.
Question: What are cross-sectional studies?
Answer: This type of investigation observes multiple groups for comparison.
Question: What is a comparative investigation?
Answer: This study follows the same subjects over an extended period and compares outcomes.
Question: What is a cohort study?
Answer: This consideration ensures a product does not cause harm to users.
Question: What is product safety?
Answer: This group is not exposed to the intervention and provides comparison data.
Question: What is the control group?
Answer: These trials can test durability, effectiveness, and safety concerns.
Question: What are randomized control trials?
Answer: More rigorous studies have less of these two things.
Question: What are bias and error?
Answer: This experimental study seeks relationships between variables without random assignment.
Question: What is a quasi-experimental study?
Answer: This evaluation determines whether a design has unnecessary steps or parts.
Question: What is efficiency?
Answer: Giving each participant an equal chance of being in any group is called this.
Question: What is randomization?
Answer: Engineers may use this type of experiment when randomized trials are too costly or unethical.
Question: What are quasi-experiments?
Answer: Investigations can be used to test scientific questions and evaluate these.
Question: What are engineering designs?
Answer: This study type is considered the highest level of evidence.
Question: What is a randomized control trial?
Answer: This factor refers to a product's ability to compete in the marketplace and generate profit.
Question: What is commercial viability?
Answer: Researchers and subjects do not know who is in the control or experimental group.
Question: What is blinding?
Answer: Multiple investigations may be needed to address each of these.
Question: What are design elements?
