- I was given a graphing activity. It was do with the measuring the reaction rate against temperature. As you can see in the images below when I plotted them it required to be a curved graph. My question is when you have to graph data like the worksheets attached do you simple go through each one or do you have to do something like a curve of best fit. I was also required to interpolate missing dataSpecifically I had to graph the rate of reaction which was measured at mm/s against temperautre. This was for a biology test. The data point were similar to these worksheets in the sense that none of the data points were overallping thy were clearly separated and at different height. BTW this subject was biology.What is the Posner task? Describe its purpose and setup (materials, conditions, etc.). What do its results (graph pictured here) indicate, and why? Reaction time (msec) 300 250 200 Invalid Neutral Valid CueHow can the Reaction Rates be determined?
