Lena Q. Posted October 10, 2012 Report Share Posted October 10, 2012 So tomorrow marks the adventure into an ecosystem for my Biology (SL). I'm testing to see what the dissolved oxygen level is in certain sectors of a stream in relationship to the crayfish population. I've assembled all my materials and things like that, but I'm wondering about controlling variables. I understand that in my conclusion I will be writing an error analysis on how the variables I was unable to efficiently control may have skewed my results. But I mean the stream is constantly flowing, so turbidity, temperature, depth where the crayfish was, and murkiness of the water could all really play a factor, only some of which I can control.My question is: Is it alright that my experiment contains these essential flaws, so long as I analyze them in my conclusion?Thank you xx Reply Link to post Share on other sites More sharing options...
GirlwiththeBlueBox Posted October 10, 2012 Report Share Posted October 10, 2012 Of course! The IB likes to see that you've incorporated thought into what might have skewed your data and I believe that is actually a requirement for the rubric for a biology IA.
