Professor sandoval is interested in examining how study breaks influence memory. she allows one group of psychology students to take a single 15-minute break while another group of psychology students takes three 5-minute breaks. what is the dependent variable in this example?

The dependent variable in this example is "the students' memory of the material".

A dependent variable is a factor that is changed by the impact of a related factor called the independent variable.

For instance, utilization is a reliant variable since it is caused and impacted by another variable: salary. In a numerical condition or model, the needy variable is the variable whose esteem is to be dictated by that condition or model. In an analysis, it is the variable whose conduct under controlled conditions (that are permitted to change in a sorted out way) is considered.  

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.
