In scientific experiments, levels of a variable reflect the specific variations a scientist can manipulate. For instance, in a helicopter experiment, if the variable is the number of paperclips attached, possible levels might include zero, one, two, and three paperclips. Embedding such variations allows researchers to observe changes and draw conclusions. This concept is crucial for designing effective experiments. Reflecting on what a level of a variable is, consider the variable of the color of light: three possible levels could be red, blue, and green.

Levels of variables • The levels of a variable are the specific ways that a scientist changes the you-change it variable • For example, in the helicopter experiment: • you-change-it variable: the number of paperclips • levels: were zero paperclips, one paperclip, 2 paperclips, 3 paperclips… • Most often, one level will be the you-change-it variable in its natural state
