1 A small 3-ounce piece of meat has about 21 grams of protein. A typical 8-ounce piece of meat could have over 50 grams of protein. 2  One 8-ounce container of yogurt has about 11 grams of protein. 3  One cup of milk has 8 grams of protein.  One cup of dry beans has about 16 grams of protein.
All of these aspects of peanut growth can be measured and can be used as dependent variables in an experiment. There are different dependent variables possible in an experiment. The investigator can choose the one he thinks is most important, or he can choose to measure more than one dependent variable.
Some researchers observe what changes occur while they are passive to determine the dependent variable. In these cases, researchers merely record the measurements and results of the dependent variable without interference. Conversely, the independent variable is thought to be the variable acted upon.Active independent variables require researchers to act, such as adjusting a temperature or dose.n these cases, researchers merely record the measurements and results of the dependent variable without interference.
