Can you go over experiment terms like positive/negative controls, null/alternate hypothesis, chi square, etc.?
yeah can we go over recognizing controls in an experiment
Ya especially null hypothesis and what’s statistically significant and what’s not
Here’s an overview for the kinds of controls:
A positive control group is where you are trying to replicate your known results. A negative control group is so that nothing will happen. Both of these can be helpful to compare the results found throughout the experiment. A negative control can help clarify whether the independent and dependent variable have a correlation to each other, and a positive control group can help with comparison of results.
A null hypothesis is similar to a negative control: it is hypothesizing that nothing will happen. Conducting a chi-square will help clarify whether the independent variable does actually impact the dependent variable.
I hope this helps!
