What does interval for Independent variable mean?

Question

matt101 · Answer

The interval refers to the range of values the variable can take on. The independent variable, in contrast to the dependent variable, is the variable that doesn't change when another variable is manipulated.

can you give me an example for an interval please @matt101

Is this question talking about a lab you're working on? If you tell me what you're dealing with, I could give you an example.

They hypothesis I have for  my lab experiment is ... 'The light intensity falling on a LDR affects the resistance of the component . I have already done this experiment to test my hypothesis  and I found out that this hypothesis is true. The independent variable which is the distance of the LDR away from the lamp on my graph goes from 0 cm to 50 cm (in tens) ,I have to find the interval for the Independent Variable. @matt101

Ermm.. I am wondering too.. what it means :P

irishboy123 · Answer

isn't it zero to 50?  follows logically from your and @matt101's prev posts?

matt101 · Answer

In this case I think the interval is more likely to be referring to the ACTUAL range of values you measured for the independent variable. You set the axis of your graph from 0 to 50 because it was convenient for the values you measured. What were though lowest and highest of light intensity that you ACTUALLY used in the experiment?
