Which of these is an example of a HYPOTHESIS?
Brand X will pop more kernels of popcorn than brand Y.
The # of kernels that pop for each brand.
Step 1. Count 100 kernels of both brands Step 2. Pop the popcorn using the same method / temperature. Step 3. Count the unpopped kernels.
Brand X had 2 unpopped kernels, Brand Y had 10 unpopped kernels

The # of kernels that pop for each brand.
Brand X popped more kernels than Brand Y.
Popping 2 brands of popcorn under the exact same conditions.
Which of the following is an example of Quantitative data?
Counting the exact number of kernels that are popped (or unpopped)
Taking a poll, study, or interview of other popcorn fans to see which brand they think pops more based on their experiences.

Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscope, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.
What is the CONTROL in this experiment?
Caffeine
The number of beats per minute (heartrate)
