i need to make a graph on excel.. my data involve putting goldfish (from the same tank and same type) into 3 different environments : acidic, neutral (control), and basic. What kind of graph should I use? just a line graph? but then what should my variables look like?
the 3 same pH on x since its independent, and then mean of all the metabolic rates on y? So would line be best or bar graph or something?
