what is another word for variable in an experiment

Finally, their final mass was recorded and we were able to calculate the percent change in mass. After each set of potato slice was soaked for 25-30 minutes, we removed them from the cups and blotted them gently on a paper towel. Then we repeated these past steps for the other sucrose solutions. Procedure: First, we were to prepare a stock solution of 1. the initial worker’s performance, it would mean that the problem is indeed the person that is currently operating the line.Materials: In this lab the materials that we used were potatoes, sucrose solution, balance scale, paper towels, plastic cups, and a plastic knife.

If there’s a significant change in the output figures of these new workers vs.

Malone should do is to replace the worker with perhaps three or four different workers, to see how productivity is affected on each case. Our concept of manipulated variable state that the independent valued identified as influential must be changed in order to study the change in the results obtained. Malone use a manipulated variable experiment to reach a conclusion about the situation? Malone suspects that the reason for this poor performance is the operator assigned to that line. He’s currently evaluating the performance of individual production lines and there’s one production line that is underperforming when compared to the quota established for it. Malone is a plant manager at a company that manufactures water bottles in different sizes. Of course, in order for this to work, the person performing the experiment has to be able to control the input of the manipulated variable. The manipulated variable experiment is designed to understand the cause-effect relationships between the elements being studied, but in order to identify and try out a manipulated variable there has to be a research or an hypothesis that backs the idea that this variable has a correlation with the dependent variable (the one that the experiment is trying to predict or study).

By analyzing these changes the person in charge of the experiment can conclude what’s the degree of influence of this variable over the element or phenomena being studied. This method evaluates the change in the results obtained by modifying a given independent variable’s value. Manipulated variables are frequently used in scientific experiments or theoretical research. Simply put, the variable is modified to assess its influence over the experiment’s overall result. Definition: A manipulated variable is an independent variable subject to the changes of an experiment to analyze its effect on a dependent variable.
