For the following experiment:
You mix syrup with water in various concentrations and put 1/4 teaspoon on a napkin. You measure the linear distance the wet stain spreads in 30 seconds from the point of origin to the farthest edge.
1. What type of graph would be best for the data?
2. What are the x and y axes?
3. What type of regression is best?
4. What are the errors in this experiment?
(This is the 1st time I've ever asked a question on here. I don't know if it's good )
1. Line (because the IV is numbers not qualities)
2. X axis is the different concentrations of the water, Y axis is the axis which shows how far the water spread
4. I'm going to only describe one error: It's unlikely that you'd drop the syrup mixture on the napkin in a perfect circle, so there could be discrepancies in the measurement of an oval-like stain (do we measure the long side or the short side?). Because there is no way to control this, this error could be best described as a random error. Because there would be discrepancies in the measurement, some measurements could be high and some could be low, depending on which side of the oval that is measured.
