I have a table of values showing the percentages of two groups and their standard errors. For example, Group A has an individual with a certain characteristic c, and their value is 14 ± 0.35% while in Group B, the individual with the same characteristic c have a value of 17 ± 0.45%. How can I determine how many standard deviations (sigmas) the data from Group A deviate from Group B in this case?How do I calculate how much the data deviates from one group to another in a table of percentages and standard errors?
