Manual with Step-by-Step Answers PDF
Case study - answer-A type of study that does NOT involve the manipulation of variables.
Descriptive investigation - answer-A study that examines a group without manipulating
variables, as exemplified by Mateo's study of mechanical and chemical engineers.
Cross-sectional studies - answer-Considered the gold standard of experimentation.
Quasi-experimental studies - answer-Used when randomized control trials cannot be used due
to ethics or cost.
Cohort studies - answer-Involve no intervention from researchers.
Commercial viability - answer-Refers to ensuring the product does not cause harm or injury to
others and requires one to ask if the product should have any warnings labeled.
Blinding in an experiment - answer-A method where researchers or participants do not know
which participants are in experimental and control groups.
Validity and reliability of an experiment - answer-Depends on multiple factors, such as blinding,
randomization, and not using a control group.

, Engineering design evaluation elements - answer-Considerations include commercial viability,
efficiency, product safety, and workability.
Randomized control trial - answer-A study that usually involves the manipulation of a variable.
Longitudinal study - answer-A form of descriptive investigation that examines subjects over a
period of time.
Efficiency - answer-An element of evaluating an engineering design that assesses how well a
product performs its intended function.
Product safety - answer-An element of evaluating an engineering design that ensures the
product does not pose risks to users.
Workability - answer-An element of evaluating an engineering design that assesses the
practicality of the product.
True or False statements - answer-A method of evaluating the validity of claims regarding
experimental designs.
Experimental design - answer-A systematic approach to investigating hypotheses through
controlled methods.
Manipulation of variables - answer-The act of changing one or more variables to observe the
effect on other variables.
