Question

Dr Eberhardt has been conducting a study in which he wants to know how much glucose is generated by blue-green algae when they are placed under blue light for 4 hours. There are two methods that he can used to determine glucose levels and he needs to know which one is more accurate. In method 1, a hexokinase activity assay is used and the mean of 10 algal samples is 120 mmol, with a standard deviation of 4.8 In method 2, a glucose oxidase activity assay is used and the mean of the same 10 algal samples is 100 mmol, the standard deviation is 4. Which method is more accurate?

both are equally accurate based on their coefficients of variation

method 2, because it has a smaller standard deviation

method 1, because although the standard deviation is greater so is the mean

you would need to know the range in order to see which is more accurate

Explanation / Answer

Correct option:

Method 1, because although the standard deviation is greater, so is mean.

EXPLANATION: Accuracy ismeasured by mean. Here, method 1 gives mean of 120 mmol which is more than method 2.

Standard deviation gives only the spread of the vaues.
