Do Show Justify
Does your data require calculation of %change? This is not likely for many of you. think, mass change of potatoes in osmosis
*
yes and I have included them and I have justified this with brief statement
no go to next question
yes, but this is currently incomplete or missing  go to next question
Does your data require a central tendency calculation ie, mean w/standard deviation. This is likely to be many of you so check
*
Yes , and it is in my report
yes but it is not in my report and I need to do this
No, at next question answer n/a
no my data is better reflected using median, mode or range and I know I have to justify this choice in the report
Did you briefly explain why your data needs a mean/ sd  have you justified this and also described what it means
*
yes
no but I will make sure to do this in my report
N/A
If you said no or N/A for mean/SD; choose why
*
correlation study  each data point is unique and using a common approximated value like mean is not meaningful/helpful
phylogeny study  not helpful for analysis
not enough data trials for SD but I did get mean or I used median/ mode/ range and justified it
didn't realize that pretty much all labs will requirre this as minimum description of describing an approximation of a common value
chose to show mode/ median or range instead and I know I must include a justification for this
Required
Do you have enough trials at each level [ min 5 trials] to calculate standard deviation?
*
yes and I have calculated the mean and the standard deviation
no and I will make sure to discuss this in my report  especially under limitations
