Below are sample questions representative of the exercises included on this worksheet and related 7.4 Designing Testable Questions and Hypotheses skill assessments:

Problem 1Difficulty: Mastery

Which statement is the best testable hypothesis for this investigation?

AThere will be a correlation between amount of particles in the air (number of vapor puffs) and light intensity at the sensor (lux).

BIf light intensity at the sensor (lux) changes, then amount of particles in the air (number of vapor puffs) was the cause.

CIf amount of particles in the air (number of vapor puffs) is higher, then light intensity at the sensor (lux) will be different, but the reason is unknown.

DIf the amount of particles in the air increases, then the light intensity at the sensor will decrease.

Solution & Explanation:The best hypothesis names one independent variable (amount of particles in the air (number of vapor puffs)) and one dependent variable (light intensity at the sensor (lux)) and predicts how changing the independent variable will cause a measurable change in the dependent variable. The other choices are questions, opinions, too vague, or mix in extra variables.

Problem 2Difficulty: Mastery

Which option states a cause-and-effect hypothesis that can be tested with measurements?,A. What is the best way to measure signal strength reading when dish angle (degrees) changes? | B. Changing dish angle (degrees) will affect many outcomes

Aincluding signal strength reading.

BIf the dish angle changes

Solution & Explanation:signal strength reading will improve (be healthier/stronger).,C,The best hypothesis names one independent variable (dish angle (degrees)) and one dependent variable (signal strength reading) and predicts how changing the independent variable will cause a measurable change in the dependent variable. The other choices are questions

Problem 3Difficulty: Mastery

Which hypothesis is both specific and testable for the investigation described?

AIf vibration frequency increases, then the time for a clear sand pattern to appear will decrease.

BIf vibration frequency (Hz) increases, time for a clear sand pattern to appear (seconds) will improve (be healthier/stronger).

CIf vibration frequency (Hz) is higher, then time for a clear sand pattern to appear (seconds) will be different, but the reason is unknown.

DThere will be a correlation between vibration frequency (Hz) and time for a clear sand pattern to appear (seconds).

Solution & Explanation:The best hypothesis names one independent variable (vibration frequency (Hz)) and one dependent variable (time for a clear sand pattern to appear (seconds)) and predicts how changing the independent variable will cause a measurable change in the dependent variable. The other choices are questions, opinions, too vague, or mix in extra variables.
