If Two signs that scores are significantly different then (a) the error bars of group will not overlap

Error bars are graphical representations of data variability that are used to indicate the error or uncertainty in a reported measurement on graphs.

The estimated error in a measurement is indicated by error bars. In other words, an error bar represents the degree of uncertainty in a value.

When the standard deviation error bars overlap significantly, it is an indication that the difference is not statistically significant. To reach a conclusion, you must conduct a statistical test.

When the standard deviation error bars overlap even less, it indicates that the difference is unlikely to be statistically significant.

For significantly different group , we also have p-value greater than 0.05

So, Option (b) is incorrect.

Hence, (a) The error bars of the groups will not overlap is correct
