Question

Having learned that the optimum sugar concentration is 25% , the students next decide to investigate whether different strains of yeast produce different amounts of alcohol. If you were going to graph the data from this experiment, what type of graph would be used? Explain why.

 

Answer 1

I would use a bar graph (x-axis representing different strains of bacteria, y-axis representing the amount of alcohol being produced). Bar graphs are useful for comparing categorical qualitative variables vs quantitative continuous variables.
