Researchers record the average time it takes rats to complete the maze. In this study, the number of feed pellets was independent as per Manipulation of the Independent Variable
Manipulation of the Independent Variable Again, manipulating an independent variable involves systematically altering its levels so that different groups of participants are exposed to different levels of that variable, or This means that the groups will be exposed to different levels at different times. Independent variables are variables that researchers manipulate to better understand how phenomena, structure, and behavior are related to the dependent variable and Alternative Hypothesis . Instrumental variables are the independent variables in an experiment. It's called "manipulated" because it's something you can change. That is, you can decide in advance whether to increase or decrease. Experiments should always have only one instrumental variable.

Forgive me if this is obvious; high school physics student here who's just learned about light and is greatly confused by all this.
Trade barriers being abolished would increase trade to a great extent the positive aspects would be that consumer would have a variety of choice to chose from and the trade barriers being abolished means no duties and taxes so the cost of the imported good would be the same in exporting and importing country hence a benefit to the consumer moreover it has negative aspects as well that no duties for the importing country and hence the local producers would be negatively affected as their sales would go down as people would be consuming more of imported good than domestic goods.
