A researcher is studying the effect of sleep on aggression, thinking that less sleep will lead to more aggression. She has some people sleep 6 hours per night, some people sleep 3 hours per night and some people sleep as much as they want. She then monitors aggressive behavior during basketball games among participants. What are the variables?
Dependent: Aggression Independent: Sleep amount

The first step of engineering is.....
What is identifying a need.

The scientific notation for 0.777
What is 7.77 x 10^-1

A researcher is curious to find out what effect classical music has on people’s level of relaxation (as measured by heart rate). He suspects that listening to classical music will make people feel more calm and relaxed. He lets one group listen to classical music for one hour. He lets another group sit in a quiet room for one hour (i.e they hear no music). After one hour, he monitors the heart rate of each participant to measure their level of relaxation.
Dependent: the heart rate Independent: Quiet vs. music

Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen window, and one on the mantel in the living room. Each plant has the same size pot and the same soil, and Lauren gives each plant the same amount of water.
Dependent: how the plant grows Independent: where the plant is located
