Can someone help with Quadratic Graphs please?

Help with adding error bars on my graphs!!?

• Hey, I have this huge biology lab where I have to make some graphs on excel that require error bars. I have battled with this for over 3 hours, asking a whole bunch of people and trying to do it myself. However, many people are selfish and didn't help me. So I'm begging someone on here to help me, please! this lab is worth a lot of marks! E-mail: [email protected] I'm thinking I can give you my e-mail and info that i need to graph and then someone could send me the graphs that they made. Whoever does this for me has a very good soul and I will love them very much! Graph 1: Concentration of Sucrose (mol/L) 1.0 0.5 0.0 Mean Initial Mass (g) 2.20 2.11 2.13 Mean Final Mass (g) 1.57 1.72 2.59 Label x-axis: Concentration of Sucrose (mol/L) Label y-axis: Mean Mass Value (g)

• Answer:

  Mean mass: add the values up, then divide 'em by the number of data!
