Data Processing: With this lab I have selected to make a data table in which the table includes the quantity of carbon dioxide produced at the end of each trial in mL, the number of trials, standard deviation, variance, and standard error. I have chosen to make a scatter plot for all of the means of the sucrose solutions including the standard error. I’ve decided to process and present my data in this form because the structure of the data table and graph clearly show the carbon dioxide produced in each sucrose solution which is the main focus of this lab. I have chosen to include standard deviation because when recording data because standard deviation helps you comprehend how much a given data point is different from the average (mean), which is helpful in this lab because this will inform you of any outliers in the mean. When finding the difference of the solution at the end of each trial you subtract the initial volume of CO2 from the CO2 produced
