On a normally distributed curve, raw scores may become meaningful if you know the standard deviation and mean of the group.
Normally Distributed Curve
A graphical representation of a distribution of data in which most values cluster around a central peak and taper off symmetrically towards either end, resembling a bell shape.
Standard Deviation
Standard deviation is a statistical measure that quantifies the amount of variation or dispersion of a set of data values from the mean.

Final Answer :
True
Explanation :
Knowing the standard deviation and mean of a normally distributed curve allows for the conversion of raw scores into z-scores, which can then be used to make meaningful interpretations about a person's performance in comparison to the rest of the group.
