Independant and Dependant Variable??? Help?
Can you tell me the Independant Var. and Dependant Var. of each sentence?
1) Students in a science class carried out an investigation in which a flashlight was pointed at a screen. They wished to find out if the distance from the light to the screen had any effect on the size of the illuminated area.
2) The number of pigs in a litter is determined by the weight of the mother pig.
3) The state Agriculture Department has been counting the number of foxes in Brown County. Will the number of foxes have any effect on the rabbit population?
4) The score on the final test depends on the number of subordinate skills attained.
5) A study was done with white rats to see if the number of offspring born dead was affected by the number of minutes of exposure to X-rays by the mother rats.
And you can tell me the definitions of IV and DV, thanks.
Okay… the trick to understanding independant and dependent variables is to know the definitions. An independent variable is something YOU control.. and a dependent variable is the results that you are looking for. (An easy trick to remember is I control the Independent variable.)
So:
1. the students wanted to manipulate the the distance of the the light- thus it is and independent variable. The size of the illuminated area is the thing they are measuring- so it is the dependent variable.
2. So the weight of the mother pig can be manipulated to find the thing you are trying to find which in this case is the number of pigs
3. The number of foxes is the independent and the rabbit population .. since its you are trying to find it is the dependent variable
4. The number of subordinate skills can be manipulated and is the independent whereas the score which you are trying to find is the dependent
5. So, since you can manipulate the number of minutes of exposure to X-rays that would be the independent variable and the dependent variable is the thing you are trying to find.. which is the number of offspring.
i hope this helps
