In order to increase typing speed, Minisoft has both redesigned its keyboard and provided a chime related to typing speed. The company wants to know if these changes affect typing speed. Which of the following represents, in order, the independent and dependent variable (s) in this study?

Dependent; speed of typing

Independent; keyboard design & chime

Explanation:

The dependent variable is the variable in a study or research that is being measured, studied, or tested by an experimenter while conducting specific research. It is completely dependent on the independent variable which can cause a change in the dependent variable.

The independent variable is the variable that is being controlled, altered, or manipulated by the researcher while conducting research and therefore affects the dependent variable.
