<p>do u need to create 6 cans with various percent of transmittance or is it ok to just set up 100% and dark. btw, what is control in this lab if we are not actually testing a hypothesis.</p>
<p>man i want chi-square sooo bad!!! lol i took stats last year</p>
<p>Actually, I'm wondering - does that mean they'll be asking in terms of O2 in L instead of kcal, like my class has been doing?</p>
<p>You can measure productivity using anything really.</p>
<p>Haha Chi-squared isn't SO bad. My teacher has been hinting at the dissolved O2 lab also.</p>

<p>I think that's because that was one of the last labs we did. I hope it's that though.</p>
