If two SEM error bars do overlap, and the sample sizes are equal or nearly equal, then you know that the P value is (much) greater than 0.05, so the difference is not statistically significant.

What is standard error of mean in Excel?
The Standard Error of Mean, also known as SEM is another measure of variability of data. It is an estimate of the deviation of a sample mean from the population mean . ... Its formula is the quotient of standard deviation and the square root of sample size.
What is the formula for calculating standard error?
SEM is calculated by taking the standard deviation and dividing it by the square root of the sample size . Standard error gives the accuracy of a sample mean by measuring the sample-to-sample variability of the sample means.
What is a good standard error?
Thus 68% of all sample means will be within one standard error of the population mean (and 95% within two standard errors). ... The smaller the standard error, the less the spread and the more likely it is that any sample mean is close to the population mean. A small standard error is thus a Good Thing.
What are standard error bars?
Error bars are graphical representations of the variability of data and used on graphs to indicate the error or uncertainty in a reported measurement. ... Error bars often represent one standard deviation of uncertainty, one standard error, or a particular confidence interval (e.g., a 95% interval).
